+dracut - low-level tool for generating an initramfs/initrd image
+
+SYNOPSIS
+--------
+*dracut* [__OPTION...__] [__<image>__ [__<kernel version>__]]
+
+DESCRIPTION
+-----------
+
+Create an initramfs <image> for the kernel with the version <kernel version>.
+If <kernel version> is omitted, then the version of the actual running
+kernel is used. If <image> is omitted or empty, depending on bootloader
+specification, the default location can be
+_/efi/<machine-id>/<kernel-version>/initrd_,
+_/boot/<machine-id>/<kernel-version>/initrd_,
+_/boot/efi/<machine-id>/<kernel-version>/initrd_,
+_/lib/modules/<kernel-version>/initrd_ or
+_/boot/initramfs-<kernel-version>.img_.
+
+dracut creates an initial image used by the kernel for preloading the block
+device modules (such as IDE, SCSI or RAID) which are needed to access the root
+filesystem, mounting the root filesystem and booting into the real system.
+
+At boot time, the kernel unpacks that archive into RAM disk, mounts and uses it
+as initial root file system. All finding of the root device happens in this
+early userspace.
+
+Initramfs images are also called "initrd".
+
+For a complete list of kernel command line options see *dracut.cmdline*(7).
+
+If you are dropped to an emergency shell, while booting your initramfs,
+the file _/run/initramfs/rdsosreport.txt_ is created, which can be saved to a
+(to be mounted by hand) partition (usually /boot) or a USB stick.
+Additional debugging info can be produced by adding **rd.debug** to the kernel
+command line. _/run/initramfs/rdsosreport.txt_ contains all logs and the output
+of some tools. It should be attached to any report about dracut problems.
+
+USAGE

+include::dracut.usage.asc[]
+
+OPTIONS
+-------
+**--kver** _<kernel version>_::
+ Set the kernel version. This enables to specify the kernel version, without
+ specifying the location of the initramfs image. For example:
+----
+# dracut --kver 3.5.0-0.rc7.git1.2.fc18.x86_64

+
+**-f, --force**::
+ Overwrite existing initramfs file.
+
+_<output file>_ **--rebuild**::
+ Append the current arguments to those with which the input initramfs image
+ was built. This option helps in incrementally building the initramfs for
+ testing. If optional _<output file>_ is not provided, the input initramfs
+ provided to rebuild will be used as output file.
+
+**-a, --add** _<list of dracut modules>_::
+ Add a space-separated list of dracut modules to the default set of modules.

+ keyboard), and the image is still portable among similar hosts.
+ With "strict" mode enabled, anything not necessary for booting the local
+ host in its current state will not be included, and modules may do some
+ extra job to save more space. Minor change of hardware or environment could
+ make the image unbootable.
++
+Default:
+ _sloppy_
+
+**--hostonly-cmdline**::
+ Store kernel command line arguments needed in the initramfs.

+ configuration (default).
+
+**--no-hostonly-i18n**::
+ Install all keyboard and font files available.
+
+**--hostonly-nics** _<list of nics>_::
+ Only enable listed NICs in the initramfs. The list can be empty, so other
+ modules can install only the necessary network drivers.
+
+**--persistent-policy** _<policy>_::
+ Use _<policy>_ to address disks and partitions.
+ _<policy>_ can be any directory name found in /dev/disk (e.g. "by-uuid",
+ "by-label"), or "mapper" to use /dev/mapper device names (default).
+
+**--fstab**::
+ Use _/etc/fstab_ instead of _/proc/self/mountinfo_.
+
+**--add-fstab** _<filename>_::
+ Add entries of _<filename>_ to the initramfs /etc/fstab.
+
+**--mount** "_<device>_ _<mountpoint>_ _<filesystem type>_ [_<filesystem options>_ [_<dump frequency>_ [_<fsck order>_]]]"::
+ Mount _<device>_ on _<mountpoint>_ with _<filesystem type>_ in the
+ initramfs. _<filesystem options>_, _<dump options>_ and _<fsck order>_ can
+ be specified, see fstab manpage for the details.
+ The default _<filesystem options>_ is "defaults".
+ The default _<dump frequency>_ is "0".
+ The default _<fsck order>_ is "2".
+
+**--mount** "_<mountpoint>_"::
+ Like above, but _<device>_, _<filesystem type>_ and _<filesystem options>_
+ are determined by looking at the current mounts.
+
+**--add-device** _<device>_ ::
+ Bring up _<device>_ in initramfs, _<device>_ should be the device name.
+ This can be useful in host-only mode for resume support when your swap is on
+ LVM or an encrypted partition.
+ [NB --device can be used for compatibility with earlier releases]
+
+**-i, --include** _<SOURCE>_ _<TARGET>_::
+ Include the files in the SOURCE directory into the
+ TARGET directory in the final initramfs. If SOURCE is a file, it will be
+ installed to TARGET in the final initramfs. This parameter can be specified
+ multiple times.
+
+**-I, --install** _<file list>_::
+ Install the space separated list of files into the initramfs.
++
+[NOTE]
+===============================
+If the list has multiple arguments, then you have to put these in quotes. For
+example:
+----
+# dracut --install "/bin/foo /sbin/bar" ...

+====
+
+**--lzma**::
+ Compress the generated initramfs using lzma.

+====
+
+**--xz**::
+ Compress the generated initramfs using xz.
++
+[WARNING]
+====
+Make sure your kernel has xz decompression support compiled in, otherwise you
+will not be able to boot. Equivalent to
+"--compress=xz --check=crc32 --lzma2=dict=1MiB -T0".

+====
+
+**--compress** _<compressor>_::
+ Compress the generated initramfs using the passed compression program. If
+ you pass it just the name of a compression program, it will call that
+ program with known-working arguments. If you pass a quoted string with
+ arguments, it will be called with exactly those arguments. Depending on what
+ you pass, this may result in an initramfs that the kernel cannot decompress.
+ The default value can also be set via the _INITRD_COMPRESS_ environment
+ variable.
+
+**--squash-compressor** _<compressor>_::
+ Compress the squashfs image using the passed compressor and compressor
+ specific options for mksquashfs. You can refer to mksquashfs manual for
+ supported compressors and compressor specific options. If squash module is
+ not called when building the initramfs, this option will not take effect.

+
+**--printsize**::
+ Print out the module install size.
+
+**--profile**::
+ Output profile information of the build process.
+
+**--ro-mnt**::
+ Mount / and /usr read-only by default.
+
+**-L, --stdlog** _<level>_::
+ [0-6] Specify logging level (to standard error).
+----
+ 0 - suppress any messages
+ 1 - only fatal errors
+ 2 - all errors
+ 3 - warnings
+ 4 - info
+ 5 - debug info (here starts lots of output)
+ 6 - trace info (and even more)
+----
+
+**--regenerate-all**::
+ Regenerate all initramfs images at the default location with the kernel
+ versions found on the system. Additional parameters are passed through.
+
+**-p, --parallel**::
+ Try to execute tasks in parallel. Currently only supported with
+ **--regenerate-all** (build initramfs images for all kernel
+ versions simultaneously).
+
+**--noimageifnotneeded**::
+ Do not create an image in host-only mode, if no kernel driver is needed
+and no /etc/cmdline/*.conf will be generated into the initramfs.
+
+**--loginstall _<directory>_**::
+ Log all files installed from the host to _<directory>_.
+
+**--uefi**::
+ Instead of creating an initramfs image, dracut will create an UEFI
+ executable, which can be executed by an UEFI BIOS. The default output
+ filename is _<EFI>/EFI/Linux/linux-$kernel$-<MACHINE_ID>-<BUILD_ID>.efi_.
+ <EFI> might be _/efi_, _/boot_ or _/boot/efi_ depending on where the ESP
+ partition is mounted. The <BUILD_ID> is taken from BUILD_ID in
+ _/usr/lib/os-release_ or if it exists _/etc/os-release_ and is left out,
+ if BUILD_ID is non-existent or empty.
+
+**--no-uefi**::
+ Disables UEFI mode.
+
+**--no-machineid**::
+ Affects the default output filename of **--uefi** and will discard the
+ <MACHINE_ID> part.
+
+**--uefi-stub _<file>_**::
+ Specifies the UEFI stub loader, which will load the attached kernel,
+ initramfs and kernel command line and boots the kernel. The default is
+ _$prefix/lib/systemd/boot/efi/linux<EFI-MACHINE-TYPE-NAME>.efi.stub_.
+
+**--uefi-splash-image _<file>_**::
+ Specifies the UEFI stub loader's splash image. Requires bitmap (**.bmp**)
+ image format.
+
+**--kernel-image _<file>_**::
+ Specifies the kernel image, which to include in the UEFI executable. The
+ default is _/lib/modules/<KERNEL-VERSION>/vmlinuz_ or
+ _/boot/vmlinuz-<KERNEL-VERSION>_.
+
+**--sbat <parameters>**::
+ Specifies the SBAT parameters, which to include in the UEFI executable. By default
+ the default SBAT string added is "sbat,1,SBAT Version,sbat,1,
+ https://github.com/rhboot/shim/blob/main/SBAT.md".
+
+**--enhanced-cpio**::
+ Attempt to use the dracut-cpio binary, which optimizes archive creation for
+ copy-on-write filesystems by using the copy_file_range(2) syscall via Rust's
+ io::copy(). When specified, initramfs archives are also padded to ensure
+ optimal data alignment for extent sharing. To retain reflink data
+ deduplication benefits, this should be used alongside the **--no-compress**
+ and **--nostrip** parameters, with initramfs source files, **--tmpdir**
+ staging area and destination all on the same copy-on-write capable
+ filesystem.
+
+ENVIRONMENT
+-----------
+
+_INITRD_COMPRESS_::

+
+_DRACUT_TESTBIN_::
+ sets the initially tested binary for detecting library paths.
+ Optional. Used for **--sysroot**. In the cross-compiled sysroot,
+ the default value (_/bin/sh_) is unusable, as it is an absolute
+ symlink and points outside the sysroot directory.
++
+Default:
+ _/bin/sh_
+
+_DRACUT_INSTALL_::
+ overrides path and options for executing _dracut-install_ internally.
+ Optional. Can be used to debug _dracut-install_ while running the
+ main dracut script.

+ overrides the NetworkManager version. Used for **--sysroot**.
+
+_DRACUT_INSTALL_PATH_::
+ overrides **PATH** environment for **dracut-install** to look for
+ binaries relative to **--sysroot**. In a cross-compiled environment
+ (e.g. Yocto), PATH points to natively built binaries that are not
+ in the host's /bin, /usr/bin, etc. **dracut-install** still needs plain
+ /bin and /usr/bin that are relative to the cross-compiled sysroot.
++
+Default:
+ _PATH_
+
+_DRACUT_INSTALL_LOG_TARGET_::
+ overrides **DRACUT_LOG_TARGET** for **dracut-install**. It allows
+ running **dracut-install* to run with different log target that
+ **dracut** runs with.
++
+Default:
+ _DRACUT_LOG_TARGET_
+
+_DRACUT_INSTALL_LOG_LEVEL_::
