By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + <signature of Ty Coon>, 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library.

So, if you see any `/dev/sda` in a setup script with more than two hard drives, +chances are, that the script works on the wrong disk. Same goes for network interfaces. + +This release is also fully `shellcheck`'ed with `ShellCheck-0.7.2` and indented with `shfmt` and `astyle`. + +The dracut project builds test containers every day for: +* `opensuse/tumbleweed-dnf:latest` +* `archlinux:latest` +* `fedora:rawhide` +* `fedora:latest` +* `fedora:33` + +These containers can easily be used to run the integration tests locally without root permissions via `podman`. +We hope this serves as a blueprint for your distribution's CI process. + +More information can be found in [docs/HACKING.md](https://github.com/dracutdevs/dracut/blob/master/HACKING.md). + +#### Bug Fixes + +* make testsuite pass on OpenSuse and Arch

notes: + Integrate the option to use an OverlayFS as the root filesystem + into the 90dmsquash-live module for testing purposes. + + The rd.live.overlay.overlayfs option allows one to request an + OverlayFS overlay. If a persistent overlay is detected at the + standard LiveOS path, the overlay & type detected will be used. + + Tested primarily with transient, in-RAM overlay boots on vfat- + formatted Live USB devices, with persistent overlay directories + on ext4-formatted Live USB devices, and with embedded, persistent + overlay directories on vfat-formatted devices. (Persistent overlay + directories on a vfat-formatted device must be in an embedded + filesystem that supports the creation of trusted.* extended + attributes, and must provide valid d_type in readdir responses.) + + The rd.live.overlay.readonly option, which allows a persistent + overlayfs to be mounted read only through a higher level transient + overlay directory, has been implemented through the multiple lower + layers feature of OverlayFS. + + The default transient DM overlay size has been adjusted up to 32 GiB. + This change supports comparison of transient Device-mapper vs. + transient OverlayFS overlay performance. A transient DM overlay + is a sparse file in memory, so this setting does not consume more + RAM for legacy applications. It does permit a user to use all of + the available root filesystem storage, and fails gently when it is + consumed, as the available free root filesystem storage on a typical + LiveOS build is only a few GiB. Thus, when booted on other- + than-small RAM systems, the transient DM overlay should not overflow. + + OverlayFS offers the potential to use all of the available free RAM + or all of the available free disc storage (on non-vfat-devices) + in its overlay, even beyond the root filesystem available space, + because the OverlayFS root filesystem is a union of directories on + two different partitions. + + This patch also cleans up some message spew at shutdown, shortens + the execution path in a couple of places, and uses persistent + DM targets where required. + +dmraid: +- added "nowatch" option in udev rule, otherwise udev would reread partitions for raid members +- allow booting from degraded MD RAID arrays + +shutdown: +- handle readonly /run on shutdown + +kernel-modules: +- add all HID drivers, regardless of hostonly mode + people swap keyboards sometimes and should be able to enter their disk password +- add usb-storage + To save the rdsosreport.txt to a USB stick, the usb-storage module is needed. +- add xennet +- add nvme + +systemd: +- add /etc/machine-info +- fixed systemd-escape call for names beginning with "-" +- install missing drop-in configuration files for + /etc/systemd/{journal.conf,system.conf} + +filesystems: +- add support to F2FS filesystem (fsck and modules) + +network: +- fix carrier detection +- correctly set mac address for ip=...:<mtu>:<mac> +- fixed vlan, bonding, bridging, team logic + call ifup for the slaves and assemble afterwards +- add mtu to list of variables to store in override +- for rd.neednet=0 a bootdev is not needed anymore +- dhclient-script.sh: add classless-static-routes support +- support for iBFT IPv6 +- support macaddr in brackets [] (commit 740c46c0224a187d6b5a42b4aa56e173238884cc) +- use arping2, if available +- support multiple default gateways from DHCP server +- fixup VLAN handling +- enhance team support +- differ between ipv6 local and global tentative +- ipv6: wait for a router advertised route +- add 'mtu' parameter for bond options +- use 'ip' instead of 'brctl' + +nbd: +- add systemd generator +- use export names instead of port numbers, because port number based + exports are deprecated and were removed. + +fcoe: +- no more /dev/shm state copying + +multipath: +- check all /dev/mapper devices if they are multipath devices, not only mpath* + +fips: +- fixed .hmac installation in FIPS mode + +plymouth: +- also trigger the acpi subsystem + +syslog: +- add imjournal.so to read systemd journal +- move start from udev to initqueue/online + +caps: +- make it a non default module + +livenet: +- support nfs:// urls in livenet-generator + +nfs: +- install all nfs modules non-hostonly + +crypt: +- support keyfiles embedded in the initramfs + +testsuite: +- add TEST-70-BONDBRIDGETEAMVLAN +- make "-cpu host" the default + +dracut-044 +========== +creation: +- better udev & systemd dir detection +- split dracut-functions.sh in dracut-init.sh and dracut-functions.sh + dracut-functions.sh can now be sourced by external tools +- detect all btrfs devices needed +- added flag file if initqueue is needed +- don't overwrite anything, if initramfs image file creation failed +- if no compressor is specified, try to find a suitable one +- drop scanning kernel config for CONFIG_MICROCODE_*_EARLY +- remove "_EARLY" from CONFIG_MICROCODE_* checks +- dracut.sh: add command line option for install_i18_all + --no-hostonly-i18n -> install_i18n_all=yes + --hostonly-i18n -> install_i18n_all=no +- --no-reproducible to turn off reproducible mode +- dracut-function.sh can now be sourced from outside of dracut +- dracut-init.sh contains all functions, which only can be used from + within the dracut infrastructure +- support --mount with just mountpoint as a parameter +- removed action_on_fail support +- removed host_modalias concept +- do not create microcode, if no firmware is available +- skip gpg files in microcode generation + +initramfs: +- ensure pre-mount (and resume) run before root fsck +- add --online option to initqueue + +qemu: +- fixed virtual machine detection + +lvm: +- remove all quirk arguments for lvm >= 2.2.221 + +dmsquash: +- fixup for checkisomd5 +- increase timeout for checkisomd5 +- use non-persistent metadata snapshots for transient overlays. +- overflow support for persistent snapshot. +- use non-persistent metadata snapshots. +- avoid an overlay for persistent, uncompressed, read-write live installations. + +multipath: +- multipath.conf included in hostonly mode +- install all multipath path selector kernel modules + +iSCSI: +- use the iBFT initiator name, if found and set +- iscsid now present in the initramfs +- iscsistart is done with systemd-run asynchrone to do things in + paralllel.

The initramfs has +(basically) one purpose in life -- getting the rootfs mounted so that +we can transition to the real rootfs. This is all driven off of +device availability. Therefore, instead of scripts hard-coded to do +various things, we depend on udev to create device nodes for us and +then when we have the rootfs's device node, we mount and carry on. +This helps to keep the time required in the initramfs as little as +possible so that things like a 5 second boot aren't made impossible as +a result of the very existence of an initramfs. + +Most of the initramfs generation functionality in dracut is provided by a bunch +of generator modules that are sourced by the main dracut script to install +specific functionality into the initramfs. They live in the modules.d +subdirectory, and use functionality provided by dracut-functions to do their +work. + +Documentation: + - [Introduction](man/dracut.asc) + - [User Manual](man/dracut.usage.asc) + +Currently dracut is developed on [github.com](https://github.com/dracutdevs/dracut). + +The release tarballs are [here](https://github.com/dracutdevs/dracut/releases). + +Gitter (chat): + - https://gitter.im/dracutdevs/Lobby + +See [News](NEWS.md) for information about changes in the releases and +the [Wiki](https://github.com/dracutdevs/dracut/wiki) to share information. + +See the github issue tracker for things which still need to be done and [Hacking](docs/HACKING.md) +for some instructions on how to get started.

They handle mangling the pathnames and (for binaries, + scripts, and kernel modules) installing dependencies as appropriate so + you do not have to. +* Scripts that end up on the initramfs should be POSIX compliant. dracut + will try to use /bin/dash as /bin/sh for the initramfs if it is available, + so you should install it on your system -- dash aims for strict POSIX + compliance to the extent possible. +* Hooks MUST be POSIX compliant -- they are sourced by the init script, + and having a bashism break your user's ability to boot really sucks. +* Generator modules should have a two digit numeric prefix -- they run in + ascending sort order. Anything in the 90-99 range is stuff that dracut + relies on, so try not to break those hooks. +* Hooks must have a .sh extension. +* Generator modules are described in more detail later on. +* We have some breakpoints for debugging your hooks. If you pass 'rdbreak' + as a kernel parameter, the initramfs will drop to a shell just before + switching to a new root. You can pass 'rdbreak=hookpoint', and the initramfs + will break just before hooks in that hookpoint run. + +Also, there is an attempt to keep things as distribution-agnostic as +possible. Every distribution has their own tool here and it's not +something which is really interesting to have separate across them. +So contributions to help decrease the distro-dependencies are welcome. + +Most of the functionality that dracut implements are actually implemented +by dracut modules. dracut modules live in modules.d, and have the following +structure: + +``` +dracut_install_dir/modules.d/ + 00modname/ + module-setup.sh + check + <other files as needed by the hook> +``` + +`00modname`: The name of the module prefixed by a two-digit numeric sort code. + The numeric code must be present and in the range of 00 - 99. + Modules with lower numbers are installed first. This is important + because the dracut install functions (which install files onto + the initrd) refuse to overwrite already installed files. This makes + it easy for an earlier module to override the functionality of a + later module, so that you can have a distro or system specific + module override or modify the functionality of a generic module + without having to patch the more generic module. + +`module-setup.sh`: + dracut sources this script to install the functionality that a + module implements onto the initrd. For the most part, this amounts + to copying files from the host system onto the initrd in a controlled + manner. + +`install()`: + This function of module-setup.sh is called to install all + non-kernel files. dracut supplies several install functions that are + specialized for different file types. Browse through dracut-functions + for more details. dracut also provides a $moddir variable if you + need to install a file from the module directory, such as an initrd + hook, a udev rule, or a specialized executable. + +`installkernel()`: + This function of module-setup.sh is called to install all + kernel related files. + + +`check()`: + dracut calls this function to check and see if a module can be installed + on the initrd. + + When called without options, check should check to make sure that + any files it needs to install into the initrd from the host system + are present. It should exit with a 0 if they are, and a 1 if they are + not. + + When called with $hostonly set, it should perform the same check + that it would without it set, and it should also check to see if the + functionality the module implements is being used on the host system. + For example, if this module handles installing support for LUKS + encrypted volumes, it should return 0 if all the tools to handle + encrypted volumes are available and the host system has the root + partition on an encrypted volume, 1 otherwise. + +`depends()`: + This function should output a list of dracut modules + that it relies upon. An example would be the nfs and iscsi modules, + which rely on the network module to detect and configure network + interfaces. + +Any other files in the module will not be touched by dracut directly. + +You are encouraged to provide a README that describes what the module is for. + + +### Hooks + +init has the following hook points to inject scripts: + +`/lib/dracut/hooks/cmdline/*.sh` + scripts for command line parsing + +`/lib/dracut/hooks/pre-udev/*.sh` + scripts to run before udev is started + +`/lib/dracut/hooks/pre-trigger/*.sh` + scripts to run before the main udev trigger is pulled + +`/lib/dracut/hooks/initqueue/*.sh` + runs in parallel to the udev trigger + Udev events can add scripts here with /sbin/initqueue. + If /sbin/initqueue is called with the "--onetime" option, the script + will be removed after it was run. + If /lib/dracut/hooks/initqueue/work is created and udev >= 143 then + this loop can process the jobs in parallel to the udevtrigger. + If the udev queue is empty and no root device is found or no root + filesystem was mounted, the user will be dropped to a shell after + a timeout. + Scripts can remove themselves from the initqueue by "rm $job". + +`/lib/dracut/hooks/pre-mount/*.sh` + scripts to run before the root filesystem is mounted + Network filesystems like NFS that do not use device files are an + exception.

Don't call any other logging function before that one! +# If you're ready with this, you can use following functions which corresponds +# clearly to levels listed in @ref intro Introduction. Here they are: +# - dtrace() +# - ddebug() +# - dinfo() +# - dwarn() +# - derror() +# - dfatal() +# They take all arguments given as a single message to be logged. See dlog() +# function for details how it works. Note that you shouldn't use dlog() by +# yourself. It's wrapped with above functions. +# +# @see dlog_init() dlog() +# +# @section conf Configuration +# +# Logging is controlled by following global variables: +# - @var stdloglvl - logging level to standard error (console output) +# - @var sysloglvl - logging level to syslog (by logger command) +# - @var fileloglvl - logging level to file +# - @var kmsgloglvl - logging level to /dev/kmsg (only for boot-time) +# - @var logfile - log file which is used when @var fileloglvl is higher +# than 0 +# and two global variables: @var maxloglvl and @var syslogfacility which <b>must +# not</b> be overwritten. Both are set by dlog_init(). @var maxloglvl holds +# maximum logging level of those three and indicates that dlog_init() was run. +# @var syslogfacility is set either to 'user' (when building initramfs) or +# 'daemon' (when booting). +# +# Logging level set by the variable means that messages from this logging level +# and above (FATAL is the highest) will be shown. Logging levels may be set +# independently for each destination (stderr, syslog, file, kmsg). +# +# @see dlog_init() + +## @brief Initializes dracut Logger. +# +# @retval 1 if something has gone wrong +# @retval 0 on success. +# +# @note This function need to be called before any other from this file. +# +# If any of the variables is not set, this function set it to default: +# - @var stdloglvl = 4 (info) +# - @var sysloglvl = 0 (no logging) +# - @var fileloglvl is set to 4 when @var logfile is set too, otherwise it's +# - @var kmsgloglvl = 0 (no logging) +# set to 0 +# +# @warning Function sets global variables @var maxloglvl and @syslogfacility. +# See file doc comment for details. +dlog_init() { + local __oldumask + local ret=0 + local errmsg + [ -z "$stdloglvl" ] && stdloglvl=4 + [ -z "$sysloglvl" ] && sysloglvl=0 + [ -z "$kmsgloglvl" ] && kmsgloglvl=0 + # Skip initialization if it's already done. + [ -n "$maxloglvl" ] && return 0 + + if [ -z "$fileloglvl" ]; then + [ -w "$logfile" ] && fileloglvl=4 || fileloglvl=0 + elif ((fileloglvl > 0)); then + if [[ $logfile ]]; then + __oldumask=$(umask) + umask 0377 + !

Both are commonly used to make +preparations before the real root file system can be mounted. + +== Rationale +Many Linux distributions ship a single, generic kernel image that is intended to +boot as wide a variety of hardware as possible. The device drivers for this +generic kernel image are included as loadable modules, as it is not possible to +statically compile them all into the one kernel without making it too large to +boot from computers with limited memory or from lower-capacity media like floppy +disks. + +This then raises the problem of detecting and loading the modules necessary to +mount the root file system at boot time (or, for that matter, deducing where or +what the root file system is). + +To further complicate matters, the root file system may be on a software RAID +volume, LVM, NFS (on diskless workstations), or on an encrypted partition. All +of these require special preparations to mount. + +Another complication is kernel support for hibernation, which suspends the +computer to disk by dumping an image of the entire system to a swap partition or +a regular file, then powering off. On next boot, this image has to be made +accessible before it can be loaded back into memory. + +To avoid having to hardcode handling for so many special cases into the kernel, +an initial boot stage with a temporary root file system +—now dubbed early user space— is used. This root file system would contain +user-space helpers that would do the hardware detection, module loading and +device discovery necessary to get the real root file system mounted. + +== Implementation +An image of this initial root file system (along with the kernel image) must be +stored somewhere accessible by the Linux bootloader or the boot firmware of the +computer. This can be: + +* The root file system itself +* A boot image on an optical disc +* A small ext2/ext3/ext4 or FAT-formatted partition on a local disk + (a _boot partition_) +* A TFTP server (on systems that can boot from Ethernet) + +The bootloader will load the kernel and initial root file system image into +memory and then start the kernel, passing in the memory address of the image. + +Depending on which algorithms were compiled statically into it, the kernel can +currently unpack initrd/initramfs images compressed with gzip, bzip2 and LZMA. + +== Mount preparations +dracut can generate a customized initramfs image which contains only whatever is +necessary to boot some particular computer, such as ATA, SCSI and filesystem +kernel modules (host-only mode). + +dracut can also generate a more generic initramfs image (default mode). + +dracut's initramfs starts only with the device name of the root file system (or +its UUID) and must discover everything else at boot time. A complex cascade of +tasks must be performed to get the root file system mounted: + +* Any hardware drivers that the boot process depends on must be loaded. All +kernel modules for common storage devices are packed onto the initramfs and then +udev pulls in modules matching the computer's detected hardware. + +* On systems which display a boot rd.splash screen, the video hardware must be +initialized and a user-space helper started to paint animations onto the display +in lockstep with the boot process. + +* If the root file system is on NFS, dracut does then: +** Bring up the primary network interface. +** Invoke a DHCP client, with which it can obtain a DHCP lease. +** Extract the name of the NFS share and the address of the NFS server from the +lease. +** Mount the NFS share. + +* If the root file system appears to be on a software RAID device, there is no +way of knowing which devices the RAID volume spans; the standard MD utilities +must be invoked to scan all available block devices with a raid signature and +bring the required ones online. + +* If the root file system appears to be on a logical volume, the LVM utilities +must be invoked to scan for and activate the volume group containing it. + +* If the root file system is on an encrypted block device: +** Invoke a helper script to prompt the user to type in a passphrase and/or +insert a hardware token (such as a smart card or a USB security dongle). + +* Create a decryption target with the device mapper. + +dracut uses udev, an event-driven hotplug agent, which invokes helper programs +as hardware devices, disk partitions and storage volumes matching certain rules +come online. This allows discovery to run in parallel, and to progressively +cascade into arbitrary nestings of LVM, RAID or encryption to get at the root +file system. + +When the root file system finally becomes visible: + +* Any maintenance tasks which cannot run on a mounted root file system +are done. +* The root file system is mounted read-only. +* Any processes which must continue running (such as the rd.splash screen helper +and its command FIFO) are hoisted into the newly-mounted root file system. + +The final root file system cannot simply be mounted over /, since that would +make the scripts and tools on the initial root file system inaccessible for any +final cleanup tasks. On an initramfs, the initial root file system cannot be +rotated away. Instead, it is simply emptied and the final root file system +mounted over the top. + +If the systemd module is used in the initramfs, the ordering of the services +started looks like <<dracutbootup7>>. + +== Dracut on shutdown + +On a systemd driven system, the dracut initramfs is also used for the shutdown +procedure. + +The following steps are executed during a shutdown: + +* systemd switches to the shutdown.target +* systemd starts + $prefix/lib/systemd/system/shutdown.target.wants/dracut-shutdown.service +* dracut-shutdown.service executes /usr/lib/dracut/dracut-initramfs-restore + which unpacks the initramfs to /run/initramfs +* systemd finishes shutdown.target +* systemd kills all processes +* systemd tries to unmount everything and mounts the remaining read-only +* systemd checks, if there is a /run/initramfs/shutdown executable +* if yes, it does a pivot_root to /run/initramfs and executes ./shutdown. + The old root is then mounted on /oldroot. + /usr/lib/dracut/modules.d/99shutdown/shutdown.sh is the shutdown executable. +* shutdown will try to unmount every /oldroot mount and calls the various + shutdown hooks from the dracut modules + +This ensures, that all devices are disassembled and unmounted cleanly. + += User Manual + +:leveloffset: 1 +include::dracut.8.asc[] + +:leveloffset: 1 +[[dracutconf5]] +include::dracut.conf.5.asc[] + +[[dracutcmdline7]] +include::dracut.cmdline.7.asc[] + +[[lsinitrd1]] +include::lsinitrd.1.asc[] + += Developer Manual + +:leveloffset: 1 +[[dracutmodules7]] +include::dracut.modules.7.asc[] + +[[dracutbootup7]] +include::dracut.bootup.7.asc[] + +:leveloffset: 0 +[appendix] +License +------- +This work is licensed under the Creative Commons Attribution/Share-Alike +License.

If you do need **rd.luks.key** to work, +you will have to exclude the "systemd" dracut module and any modules +that depend on it. See *dracut.conf*(5) and +https://bugzilla.redhat.com/show_bug.cgi?id=905683 for more +information. + +**rd.luks.key=**_<keypath>[:<keydev>[:<luksdev>]]_:: + _<keypath>_ is the pathname of a key file, relative to the root + of the filesystem on some device. It's REQUIRED. When + _<keypath>_ ends with '.gpg' it's considered to be key encrypted + symmetrically with GPG. You will be prompted for the GPG password on + boot. GPG support comes with the 'crypt-gpg' module, which needs to be + added explicitly. ++ +_<keydev>_ identifies the device on which the key file resides. It may +be the kernel name of the device (should start with "/dev/"), a UUID +(prefixed with "UUID=") or a label (prefix with "LABEL="). You don't +have to specify a full UUID. Just its beginning will suffice, even if +its ambiguous. All matching devices will be probed. This parameter is +recommended, but not required. If it's not present, all block devices will +be probed, which may significantly increase boot time. ++ +If _<luksdev>_ is given, the specified key will only be used for +the specified LUKS device. Possible values are the same as for +_<keydev>_. Unless you have several LUKS devices, you don't have to +specify this parameter. The simplest usage is: ++ +[listing] +.Example +-- +rd.luks.key=/foo/bar.key +-- ++ +As you see, you can skip colons in such a case. + +[NOTE] +=============================== +Your LUKS partition must match your key file. + +dracut provides keys to cryptsetup with _-d_ (an older alias for +_--key-file_). This uses the entire binary +content of the key file as part of the secret. If +you pipe a password into cryptsetup *without* _-d_ or _--key-file_, +it will be treated as text user input, and only characters before +the first newline will be used. Therefore, when you're creating +an encrypted partition for dracut to mount, and you pipe a key into +_cryptsetup luksFormat_,you must use _-d -_. + +Here is an example for a key encrypted with GPG (warning: +_--batch-mode_ will overwrite the device without asking for +confirmation): + +[listing] +-- +gpg --quiet --decrypt rootkey.gpg | \ +cryptsetup --batch-mode --key-file - \ + luksFormat /dev/sda47 +-- + +If you use unencrypted key files, just use the key file pathname +instead of the standard input.

This +method ensures a relatively fast boot and lower RAM usage. Users **must be +careful** to avoid writing too many blocks to a snapshot volume. Once the +blocks of the snapshot overlay are exhausted, the root filesystem becomes +read-only and may cause application failures. The snapshot overlay file is +marked 'Overflow', and a difficult recovery is required to repair and enlarge +the overlay offline. Non-persistent overlays are sparse files in RAM that only +consume content space as required blocks are allocated. They default to an +apparent size of 32 GiB in RAM. The size can be adjusted with the +**rd.live.overlay.size=** kernel command line option. ++ +The filesystem structure is traditionally expected to be: ++ +[listing] +-- +squashfs.img | SquashFS from LiveCD .iso + !(mount) + /LiveOS + |- rootfs.img | Filesystem image to mount read-only + !(mount) + /bin | Live filesystem + /boot | + /dev | + ... | +-- ++ +For OverlayFS mount overlays, the filesystem structure may also be a direct +compression of the root filesystem: ++ +[listing] +-- +squashfs.img | SquashFS from LiveCD .iso + !(mount) + /bin | Live filesystem + /boot | + /dev | + ... | +-- ++ +Dracut uses one of the overlay methods of live booting by default. No +additional command line options are required other than **root=live:<URL>** to +specify the location of your squashed filesystem. ++ +- The compressed SquashFS image can be copied during boot to RAM at +`/run/initramfs/squashed.img` by using the **rd.live.ram=1** option. +- A device with a persistent overlay can be booted read-only by using the +**rd.live.overlay.readonly** option on the kernel command line. This will +either cause a temporary, writable overlay to be stacked over a read-only +snapshot of the root filesystem or the OverlayFS mount will use an additional +lower layer with the root filesystem. ++ +Uncompressed live filesystem image::: +When the live system was installed with the '--skipcompress' option of the +__livecd-iso-to-disk__ installation script for Live USB devices, the root +filesystem image, __rootfs.img__, is expanded on installation and no SquashFS +is involved during boot. ++ +- If **rd.live.ram=1** is used in this situation, the full, uncompressed +root filesystem is copied during boot to `/run/initramfs/rootfs.img` in the +`/run` tmpfs. ++ +- If **rd.live.overlay=none** is provided as a kernel command line option, +a writable, linear Device-mapper target is created on boot with no overlay. + +Writable filesystem image::: +The system will retrieve a compressed filesystem image, extract it to +`/run/initramfs/fsimg/rootfs.img`, connect it to a loop device, create a +writable, linear Device-mapper target at `/dev/mapper/live-rw`, and mount that +as a writable volume at `/`. More RAM is required during boot but the live +filesystem is easier to manage if it becomes full. Users can make a filesystem +image of any size and that size will be maintained when the system boots. There +is no persistence of root filesystem changes between boots with this option. ++ +The filesystem structure is expected to be: ++ +[listing] +-- +rootfs.tgz | Compressed tarball containing filesystem image + !(unpack) + /rootfs.img | Filesystem image at /run/initramfs/fsimg/ + !(mount) + /bin | Live filesystem + /boot | + /dev | + ... | +-- ++ +To use this boot option, ensure that **rd.writable.fsimg=1** is in your kernel +command line and add the **root=live:<URL>** to specify the location +of your compressed filesystem image tarball or SquashFS image. +===================== + +**rd.writable.fsimg=**1:: +Enables writable filesystem support.

You can use the **rootflags** option to +set mount options for the live filesystem as well __(see documentation about +rootflags in the **Standard** section above)__. +This implies that the whole image is copied to RAM before the boot continues. ++ +NOTE: There must be enough free RAM available to hold the complete image. ++ +This method is very suitable for diskless boots. + +**rd.minmem=**__<megabyte>__:: +Specify minimum free RAM in MB after copying a live disk image into memory. +The default is 1024. ++ +This parameter only applies together with the parameters rd.writable.fsimg +or rd.live.ram. + +**root=**live:__<url>__:: +Boots a live image retrieved from __<url>__.

In this use case, this means +that memory is given back to the kernel when the filesystem does not claim it +anymore. + +**rd.live.overlay.overlayfs=**1:: +Enables the use of the *OverlayFS* kernel module, if available, to provide a +copy-on-write union directory for the root filesystem. OverlayFS overlays are +directories of the files that have changed on the read-only base (lower) +filesystem. The root filesystem is provided through a special overlay type +mount that merges the lower and upper directories. If an OverlayFS upper +directory is not present on the boot device, a tmpfs directory will be created +at `/run/overlayfs` to provide temporary storage. Persistent storage can be +provided on vfat or msdos formatted devices by supplying the OverlayFS upper +directory within an embedded filesystem that supports the creation of trusted.* +extended attributes and provides a valid d_type in readdir responses, such as +with ext4 and xfs. On non-vfat-formatted devices, a persistent OverlayFS +overlay can extend the available root filesystem storage up to the capacity of +the LiveOS disk device. ++ +If a persistent overlay is detected at the standard LiveOS path, the overlay & +overlay type detected, whether OverlayFS or Device-mapper, will be used. ++ +The **rd.live.overlay.readonly** option, which allows a persistent overlayfs to +be mounted read-only through a higher level transient overlay directory, has +been implemented through the multiple lower layers feature of OverlayFS. + + +ZIPL +~~~~ +**rd.zipl=**__<path to blockdevice>__:: + Update the dracut commandline with the values found in the + _dracut-cmdline.conf_ file on the given device. + The values are merged into the existing commandline values + and the udev events are regenerated. ++ +[listing] +.Example +-- +rd.zipl=UUID=0fb28157-99e3-4395-adef-da3f7d44835a +-- + +CIO_IGNORE +~~~~~~~~~~ +**rd.cio_accept=**__<device-ids>__:: + Remove the devices listed in <device-ids> from the default + cio_ignore kernel command-line settings. + <device-ids> is a list of comma-separated CCW device ids. + The default for this value is taken from the + _/boot/zipl/active_devices.txt_ file. ++ +[listing] +.Example +-- +rd.cio_accept=0.0.0180,0.0.0800,0.0.0801,0.0.0802 +-- + +Plymouth Boot Splash +~~~~~~~~~~~~~~~~~~~~ +**plymouth.enable=0**:: + disable the plymouth bootsplash completely. + +**rd.plymouth=0**:: + disable the plymouth bootsplash only for the initramfs. + +Kernel keys +~~~~~~~~~~~ +**masterkey=**__<kernel master key path name>__:: + Set the path name of the kernel master key. ++ +[listing] +.Example +-- +masterkey=/etc/keys/kmk-trusted.blob +-- + +**masterkeytype=**__<kernel master key type>__:: + Set the type of the kernel master key. ++ +[listing] +.Example +-- +masterkeytype=trusted +-- + +**evmkey=**__<EVM HMAC key path name>__:: + Set the path name of the EVM HMAC key. ++ +[listing] +.Example +-- +evmkey=/etc/keys/evm-trusted.blob +-- + +**evmx509=**__<EVM X.509 cert path name>__:: + Set the path name of the EVM X.509 certificate. ++ +[listing] +.Example +-- +evmx509=/etc/keys/x509_evm.der +-- + +**ecryptfskey=**__<eCryptfs key path name>__:: + Set the path name of the eCryptfs key. ++ +[listing] +.Example +-- +ecryptfskey=/etc/keys/ecryptfs-trusted.blob +-- + +Deprecated, renamed Options +~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Here is a list of options, which were used in dracut prior to version 008, and +their new replacement. + +rdbreak:: rd.break + +rd.ccw:: rd.znet +rd_CCW:: rd.znet + +rd_DASD_MOD:: rd.dasd + +rd_DASD:: rd.dasd + +rdinitdebug rdnetdebug:: rd.debug + +rd_NO_DM:: rd.dm=0 + +rd_DM_UUID:: rd.dm.uuid + +rdblacklist:: rd.driver.blacklist + +rdinsmodpost:: rd.driver.post + +rdloaddriver:: rd.driver.pre + +rd_NO_FSTAB:: rd.fstab=0 + +rdinfo:: rd.info + +check:: rd.live.check + +rdlivedebug:: rd.live.debug + +live_dir:: rd.live.dir + +liveimg:: rd.live.image + +overlay:: rd.live.overlay + +readonly_overlay:: rd.live.overlay.readonly + +reset_overlay:: rd.live.overlay.reset + +live_ram:: rd.live.ram + +rd_NO_CRYPTTAB:: rd.luks.crypttab=0 + +rd_LUKS_KEYDEV_UUID:: rd.luks.keydev.uuid + +rd_LUKS_KEYPATH:: rd.luks.keypath + +rd_NO_LUKS:: rd.luks=0 + +rd_LUKS_UUID:: rd.luks.uuid + +rd_NO_LVMCONF:: rd.lvm.conf + +rd_LVM_LV:: rd.lvm.lv + +rd_NO_LVM:: rd.lvm=0 + +rd_LVM_VG:: rd.lvm.vg + +rd_NO_MDADMCONF:: rd.md.conf=0 + +rd_NO_MDIMSM:: rd.md.imsm=0 + +rd_NO_MD:: rd.md=0 + +rd_MD_UUID:: rd.md.uuid + +rd_NO_MULTIPATH: rd.multipath=0 + +rd_NFS_DOMAIN:: rd.nfs.domain + +iscsi_initiator:: rd.iscsi.initiator + +iscsi_target_name:: rd.iscsi.target.name + +iscsi_target_ip:: rd.iscsi.target.ip + +iscsi_target_port:: rd.iscsi.target.port + +iscsi_target_group:: rd.iscsi.target.group + +iscsi_username:: rd.iscsi.username + +iscsi_password:: rd.iscsi.password + +iscsi_in_username:: rd.iscsi.in.username + +iscsi_in_password:: rd.iscsi.in.password + +iscsi_firmware:: rd.iscsi.firmware=0 + +rd_NO_PLYMOUTH:: rd.plymouth=0 + +rd_retry:: rd.retry + +rdshell:: rd.shell + +rd_NO_SPLASH:: rd.splash + +rdudevdebug:: rd.udev.debug + +rdudevinfo:: rd.udev.info + +rd_NO_ZFCPCONF:: rd.zfcp.conf=0 + +rd_ZFCP:: rd.zfcp + +rd_ZNET:: rd.znet + +KEYMAP:: vconsole.keymap + +KEYTABLE:: vconsole.keymap + +SYSFONT:: vconsole.font + +CONTRANS:: vconsole.font.map + +UNIMAP:: vconsole.font.unimap + +UNICODE:: vconsole.unicode + +EXT_KEYMAP:: vconsole.keymap.ext + +Configuration in the Initramfs +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +_/etc/conf.d/_:: + Any files found in _/etc/conf.d/_ will be sourced in the initramfs to + set initial values.

All +modules are located in _/usr/lib/dracut/modules.d_ or in _<git-src>/modules.d_. +The most basic dracut module is _99base_. In _99base_ the initial shell script +init is defined, which gets run by the kernel after initramfs loading. Although +you can replace init with your own version of _99base_, this is not encouraged. +Instead you should use, if possible, the hooks of dracut. All hooks, and the +point of time in which they are executed, are described in <<stages>>. + +The main script, which creates the initramfs is dracut itself. It parses all +arguments and sets up the directory, in which everything is installed. It then +executes all check, install, installkernel scripts found in the modules, which +are to be processed. After everything is installed, the install directory is +archived and compressed to the final initramfs image. All helper functions used +by check, install and installkernel are found in in the file _dracut-functions_. +These shell functions are available to all module installer (install, +installkernel) scripts, without the need to source _dracut-functions_. + +A module can check the preconditions for install and installkernel with the +check script. Also dependencies can be expressed with check. If a module passed +check, install and installkernel will be called to install all of the necessary +files for the module. To split between kernel and non-kernel parts of the +installation, all kernel module related parts have to be in installkernel. All +other files found in a module directory are module specific and mostly are hook +scripts and udev rules. + + +[[stages]] +== Boot Process Stages + +dracut modules can insert custom script at various points, to control the boot +process. +These hooks are plain directories containing shell scripts ending with ".sh", +which are sourced by init. +Common used functions are in _dracut-lib.sh_, which can be sourced by any script. + +=== Hook: cmdline + +The _cmdline_ hook is a place to insert scripts to parse the kernel command line +and prepare the later actions, like setting up udev rules and configuration +files. + +In this hook the most important environment variable is defined: root. The +second one is rootok, which indicates, that a module claimed to be able to parse +the root defined. So for example, **root=**__iscsi:....__ will be claimed by the +iscsi dracut module, which then sets rootok. + +=== Hook: pre-udev + +This hook is executed right after the cmdline hook and a check if root and +rootok were set. Here modules can take action with the final root, and before +udev has been run. + +=== Start Udev + +Now udev is started and the logging for udev is setup. + +=== Hook: pre-trigger + +In this hook, you can set udev environment variables with **udevadm control +--property=KEY=_value_** or control the further execution of udev with +udevadm. + +=== Trigger Udev + +udev is triggered by calling udevadm trigger, which sends add events for all +devices and subsystems. + +=== Main Loop + +In the main loop of dracut loops until udev has settled and +all scripts in _initqueue/finished_ returned true. +In this loop there are three hooks, where scripts can be inserted +by calling /sbin/initqueue. + +==== Initqueue + +This hook gets executed every time a script is inserted here, regardless of the +udev state. + +==== Initqueue settled + +This hook (initqueue/settled) gets executed every time udev has settled. + +==== Initqueue timeout + +This hook (initqueue/timeout) gets executed, when the main loop counter becomes +half of the rd.retry counter. + +==== Initqueue online + +This hook (initqueue/online) gets executed whenever a network interface comes online +(that is, once it is up and configured by the configured network module). + +==== Initqueue finished + +This hook (initqueue/finished) is called after udev has settled and +if all scripts herein return 0 the main loop will be ended. +Arbitrary scripts can be added here, to loop in the +initqueue until something happens, which a dracut module wants to wait for. + +=== Hook: pre-mount + +Before the root device is mounted all scripts in the hook pre-mount are +executed. In some cases (e.g. NFS) the real root device is already mounted, +though. + +=== Hook: mount + +This hook is mainly to mount the real root device. + +=== Hook: pre-pivot + +This hook is called before cleanup hook, This is a good place for +actions other than cleanups which need to be called before pivot. + +=== Hook: cleanup + +This hook is the last hook and is called before init finally switches root to +the real root device. This is a good place to clean up and kill processes not +needed anymore. + + +=== Cleanup and switch_root + +Init (or systemd) kills all udev processes, cleans up the environment, +sets up the arguments for the real init process and finally calls switch_root. +switch_root removes the whole filesystem hierarchy of the initramfs, +chroot()s to the real root device and calls /sbin/init with the specified +arguments. + +To ensure all files in the initramfs hierarchy can be removed, all processes +still running from the initramfs should not have any open file descriptors left. + +== Network Infrastructure + +FIXME + +== Writing a Module + +A simple example module is _90kernel-modules_, which modprobes a kernel module +after udev has settled and the basic device drivers have been loaded. + +All module installation information is in the file module-setup.sh. + +First we create a check() function, which just exits with 0 indicating that this +module should be included by default. + +check(): +---- +return 0 +---- + +Then we create the install() function, which installs a cmdline hook with +priority number 20 called _parse-insmodpost.sh_.

With this flexibility, you can easily +boot from a changed root partition, without the need to recompile the initramfs +image. So, you could completely change your root partition (move it inside a md +raid with encryption and LVM on top), as long as you specify the correct +filesystem LABEL or UUID on the kernel command line for your root device, dracut +will find it and boot from it. + +The kernel command line can also be provided by the dhcp server with the +root-path option. See <<NetworkBoot>>. + +For a full reference of all kernel command line parameters, +see *dracut.cmdline*(7). + +To get a quick start for the suitable kernel command line on your system, +use the __--print-cmdline__ option: +---- +# dracut --print-cmdline + root=UUID=8b8b6f91-95c7-4da2-831b-171e12179081 rootflags=rw,relatime,discard,data=ordered rootfstype=ext4 +---- + +==== Specifying the root Device +This is the only option dracut really needs to boot from your root partition. +Because your root partition can live in various environments, there are a lot of +formats for the root= option. The most basic one is root=_++<path to device +node>++_: +---- +root=/dev/sda2 +---- + +Because device node names can change, dependent on the drive ordering, you are +encouraged to use the filesystem identifier (UUID) or filesystem label (LABEL) +to specify your root partition: +---- +root=UUID=19e9dda3-5a38-484d-a9b0-fa6b067d0331 +---- + +or + +---- +root=LABEL=myrootpartitionlabel +---- + +To see all UUIDs or LABELs on your system, do: +---- +# ls -l /dev/disk/by-uuid +---- + +or + +---- +# ls -l /dev/disk/by-label +---- + +If your root partition is on the network see <<NetworkBoot>>. + +==== Keyboard Settings +If you have to input passwords for encrypted disk volumes, you might want to set +the keyboard layout and specify a display font. + +A typical german kernel command line would contain: +---- +rd.vconsole.font=eurlatgr rd.vconsole.keymap=de-latin1-nodeadkeys rd.locale.LANG=de_DE.UTF-8 +---- + +Setting these options can override the setting stored on your system, if you use +a modern init system, like systemd. + +==== Blacklisting Kernel Modules +Sometimes it is required to prevent the automatic kernel module loading of a +specific kernel module. To do this, just add rd.driver.blacklist=_++<kernel +module name>++_, with _++<kernel module name>++_ not containing the _.ko_ +suffix, to the kernel command line. For example: +---- +rd.driver.blacklist=mptsas rd.driver.blacklist=nouveau +---- + +The option can be specified multiple times on the kernel command line. + +==== Speeding up the Boot Process +If you want to speed up the boot process, you can specify as much information +for dracut on the kernel command as possible. For example, you can tell dracut, +that you root partition is not on a LVM volume or not on a raid partition, or +that it lives inside a specific crypto LUKS encrypted volume. By default, dracut +searches everywhere. A typical dracut kernel command line for a plain primary or +logical partition would contain: +---- +rd.luks=0 rd.lvm=0 rd.md=0 rd.dm=0 +---- + +This turns off every automatic assembly of LVM, MD raids, DM raids and +crypto LUKS. + +Of course, you could also omit the dracut modules in the initramfs creation +process, but then you would lose the possibility to turn it on on demand. + + +[[Injecting]] +=== Injecting custom Files +To add your own files to the initramfs image, you have several possibilities. + +The --include option let you specify a source path and a target path. +For example +---- +# dracut --include cmdline-preset /etc/cmdline.d/mycmdline.conf initramfs-cmdline-pre.img +---- +will create an initramfs image, where the file cmdline-preset will be copied +inside the initramfs to _/etc/cmdline.d/mycmdline.conf_. --include can only +be specified once. + + +---- +# mkdir -p rd.live.overlay/etc/cmdline.d +# mkdir -p rd.live.overlay/etc/conf.d +# echo "ip=dhcp" >> rd.live.overlay/etc/cmdline.d/mycmdline.conf +# echo export FOO=testtest >> rd.live.overlay/etc/conf.d/testvar.conf +# echo export BAR=testtest >> rd.live.overlay/etc/conf.d/testvar.conf +# tree rd.live.overlay/ +rd.live.overlay/ +`-- etc + |-- cmdline.d + | `-- mycmdline.conf + `-- conf.d + `-- testvar.conf + +# dracut --include rd.live.overlay / initramfs-rd.live.overlay.img +---- + +This will put the contents of the rd.live.overlay directory into the root of the +initramfs image. + +The --install option let you specify several files, which will get installed in +the initramfs image at the same location, as they are present on initramfs +creation time. + + +---- +# dracut --install 'strace fsck.ext4 ssh' initramfs-dbg.img +---- + +This will create an initramfs with the strace, fsck.ext4 and ssh executables, +together with the libraries needed to start those. The --install option can be +specified multiple times. + + +[[NetworkBoot]] +=== Network Boot + +If your root partition is on a network drive, you have to have the network +dracut modules installed to create a network aware initramfs image. + +If you specify ip=dhcp on the kernel command line, then dracut asks a dhcp +server about the ip address for the machine. The dhcp server can also serve an +additional root-path, which will set the root device for dracut. With this +mechanism, you have static configuration on your client machine and a +centralized boot configuration on your TFTP/DHCP server. If you can't pass a +kernel command line, then you can inject _/etc/cmdline.d/mycmdline.conf_, with a +method described in <<Injecting>>. + +==== Reducing the Image Size + +To reduce the size of the initramfs, you should create it with by omitting all +dracut modules, which you know, you don't need to boot the machine. + +You can also specify the exact dracut and kernel modules to produce a very tiny +initramfs image. + +For example for a NFS image, you would do: + + +---- +# dracut -m "nfs network base" initramfs-nfs-only.img +---- + +Then you would boot from this image with your target machine and reduce the size +once more by creating it on the target machine with the --host-only option: + + +---- +# dracut -m "nfs network base" --host-only initramfs-nfs-host-only.img +---- + +This will reduce the size of the initramfs image significantly. + + +== Troubleshooting + +If the boot process does not succeed, you have several options to debug the +situation. + +[[identifying-your-problem-area]] +=== Identifying your problem area +.

The required steps will depend on how your +root volume is configured. Common scenarios include: + +* A block device (e.g. _/dev/sda7_) +* A LVM logical volume (e.g. _/dev/VolGroup00/LogVol00_) +* An encrypted device + (e.g. _/dev/mapper/luks-4d5972ea-901c-4584-bd75-1da802417d83_) +* A network attached device + (e.g. _netroot=iscsi:@192.168.0.4::3260::iqn.2009-02.org.example:for.all_) + +The exact method for locating and preparing will vary. However, to continue with +a successful boot, the objective is to locate your root volume and create a +symlink _/dev/root_ which points to the file system. For example, the following +example demonstrates accessing and booting a root volume that is an encrypted +LVM Logical volume. + +.

Introduction + +i18n module provides internationalization for initramfs at runtime. It +is intended to be generic across different GNU/Linux distributions. + +i18n and keyboard settings are stored in different files among +distributions. To deal with it avoiding hardcoding those differences in +the installation script we handle it by mappings between variables used +by dracut and the ones in the system. Package maintainer is expected to +create those for his/her distribution and it's appreciated to share it +with us, so we can include it in source package. + + +1. Hostonly vs Generic + +If you invoke dracut with '-H' option, i18n module install script will +gather variables values from your configuration files using mappings +provided in "/etc/dracut.conf.d/<foo>.conf". Those variables will be +put in "etc/vconsole.conf" and "etc/locale.conf" files inside initramfs +image. Next it will install only declared font, keymaps and so. + +When building generic image (dracut without '-H' option), install script +copies all content of directories: consolefonts, consoletrans, unimaps +and keymaps to image. Take into account that's about 4 MiB. + + +2. Configuration + +2.1. Variables + +The following variables are used by i18n install script and at initramfs +runtime: + + KEYMAP - keyboard translation table loaded by loadkeys + KEYTABLE - base name for keyboard translation table; if UNICODE is + true, Unicode version will be loaded. Overrides KEYMAP. + EXT_KEYMAPS - list of extra keymaps to bo loaded (sep. by space) + UNICODE - boolean, indicating UTF-8 mode + FONT - console font + FONT_MAP - see description of '-m' parameter in setfont manual + FONT_UNIMAP - see description of '-u' parameter in setfont manual + +The following are appended to EXT_KEYMAPS only during build time: + + UNIKEYMAP + GRP_TOGGLE + +They were used in 10redhat-i18n module, but not sure of its purpose. +I'm leaving it in case... The following are taken from the environment: + + LANG + LC_ALL + +If UNICODE variable is not provided, script indicates if UTF-8 should be +used on the basis of LANG value (if it ends with ".utf8" or similar). + + +2.2. Setting up mappings + +Mappings between variables listed in 2.1. and the ones spread around +your system are set up in /etc/dracut.conf.d/<foo>.conf. You need to +assign mappings to i18n_vars.

Additional settings + +If you encounter following error message: "Directories consolefonts, +consoletrans, keymaps, unimaps not found.", you can provide path where +those directories lie in your system by setting kbddir in configuration +file (the same where you put mappings). + + +3. Kernel parameters + +If you create generic initramfs you can set up i18n by kernel +parameters using variables listed in 2.1.
