+Bugfixes:
+
+* copy.c: set the right chattrs before copying files and others after
+
+* Many manager configuration settings that are only applicable to user
+ manager or system manager can be always set. It would be better to reject
+ them when parsing config.
+
+* Clarify what IPAddress* matches (source, destination, both?)
+
+External:
+
+* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
+
+* wiki: update journal format documentation for lz4 additions
+
+Janitorial Clean-ups:
+
+* Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
+
+* rework mount.c and swap.c to follow proper state enumeration/deserialization
+ semantics, like we do for device.c now
+
+Features:
+
+* make MAINPID= message reception checks even stricter: if service uses User=,
+ then check sending UID and ignore message if it doesn't match the user or
+ root.
+
+* maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
+ is issued.
+
+* when importing an fs tree with machined, optionally apply userns-rec-chown
+
+* when importing an fs tree with machined, complain if image is not an OS
+
+* Maybe introduce a helper safe_exec() or so, which is to execve() which
+ safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
+ to 1K implicitly, unless explicitly opted-out.
+
+* rework seccomp/nnp logic that that even if User= is used in combination with
+ a seccomp option we don't have to set NNP. For that, change uid first whil
+ keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
+
+* add a concept for automatically loading per-unit secrets off disk and
+ inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
+ ConfigurationDirectory=.
+
+* when no locale is configured, default to UEFI's PlatformLang variable
+
+* When logind.conf contains HandleLidSwitch=suspend-then-hibernate and we can't
+ hibernate because the swap partition isn't large enough, still suspend
+
+* bootctl: implement Type #2 boot loader entry discovery
+
+* bootctl,sd-boot: actually honour the "architecture" key
+
+* when a socket unit is spawned with an AF_UNIX path in /var/run, complain and
+ patch it to use /run instead
+
+* set memory.oom.group in cgroup v2 for all leaf cgroups (kernel v4.19+)
+
+* add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
+ usefaultd() and make systemd-analyze check for it.
+
+* paranoia: whenever we process passwords, call mlock() on the memory
+ first. i.e. look for all places we use string_erase()/string_free_erase() and
+ augment them with mlock()
+
+* whenever oom_kill memory.event event is triggered print a nice log message
+
+* Move RestrictAddressFamily= to the new cgroup create socket
+
+* support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
+ patching around
+
+* maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
+ log.c and sd-journal-send
+
+* chown() tty a service is attached to after the service goes down
+
+* optionally: turn on cgroup delegation for per-session scope units
+
+* introduce per-unit (i.e. per-slice, per-service) journal log size limits.
+
+* optionally, if a per-partition GPT flag is set for the root/home/… partitions
+ format the partition on next boot and unset the flag, in order to implement
+ factory reset. also, add a second flag that simply indicates whether such a
+ scheme is supported. then, add a tool (or maybe beef up systemd-dissect) to
+ show state of these flags, and optionally trigger such a factory reset on
+ next boot by setting the flag.
+
+* sd-boot: search drop-ins in $BOOT, too
+
+* sd-boot: add "oneshot boot timeout" variable support
+
+* sd-boot: automatically load EFI modules from some drop-in dir, so that people
+ can add in file system drivers and such
+
+* esp generator: also mount $BOOT if found
+
+* sd-boot: optionally, show boot menu when previous default boot item has
+ non-zero "tries done" count
+
+* logind: add "boot into bootmenu" API, and possibly even "boot into windows"
+ and "boot into macos".
+
+* bootspec.c: also enumerate EFI unified kernel images.
+
+* maybe set a special xattr on cgroups that have delegate=yes set, to make it
+ easy to mark cut points
+
+* introduce an option (or replacement) for "systemctl show" that outputs all
+ properties as JSON, similar to busctl's new JSON output. In contrast to that
+ it should skip the variant type string though.
+
+* augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
+ contains some identifier for the project, which allows us to include
+ clickable links to source files generating these log messages. The identifier
+ could be some abberviated URL prefix or so (taking inspiration from Go
+ imports). For example, for systemd we could use
+ CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
+ sufficient to build a link by prefixing "http://" and suffixing the
+ CODE_FILE.
+
+* when outputting log data with journalctl and the log data includes references
+ to configuration files (CONFIG_FILE=), create a clickable link for it.
+
+* Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
+ make clickable links from log messages carrying a MESSAGE_ID, that lead to
+ some explanatory text online.
+
+* maybe extend .path units to expose fanotify() per-mount change events
+
+* Add a "systemctl list-units --by-slice" mode or so, which rearranges the
+ output of "systemctl list-units" slightly by showing the tree structure of
+ the slices, and the units attached to them.
+
+* the a-posteriori stopping of units bound to units that disappeared logic
+ should be reworked: there should be a queue of units, and we should only
+ enqeue stop jobs from a defer event that processes queue instead of
+ right-away when we find a unit that is bound to one that doesn't exist
+ anymore. (similar to how the stop-unneeded queue has been reworked the same
+ way)
+
+* nspawn: make nspawn suitable for shell pipelines: instead of triggering a
+ hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
+ for hangup or ^D before passing on the EOF.
+
+* When reloading configuration PID 1 should reset all its properties to the
+ original defaults before calling parse_config()
+
+* Add OnTimezoneChange= and OnTimeChange= stanzas to .timer units in order to
+ schedule events based on time and timezone changes.
+
+* nspawn: greater control over selinux label?
+
+* hibernate/s2h: make this robust and safe to enable in Fedora by default.
+ Specifically:
+
+ 1. add resume_offset support to the resume code (i.e. support swap files
+ properly)
+ 2. check if swap is on weird storage and refuse if so
+ 3. add autodetection of hibernation images
+
+* cgroups: use inotify to get notified when somebody else modifies cgroups
+ owned by us, then log a friendly warning.
+
+* beef up log.c with support for stripping ANSI sequences from strings, so that
+ it is OK to include them in log strings. This would be particularly useful so
+ that our log messages could contain clickable links for example for unit
+ files and suchlike we operate on.
+
+* add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
+
+* add attach --enable and attach --now (for attach+enable+start)
+
+* sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
+ selected user is resolvable in the service even if it ships its own /etc/passwd)
+
+* Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
+ other doesn't. What a desaster. Probably to exclude it. Also
+ DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
+ numbers.
+
+* Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
+ usually IN_ATTRIB is the right way to watch deleted files, as the former only
+ fires when a file is actually removed from disk, i.e. the link count drops to
+ zero and is not open anymore, while the latter happens when a file is
+ unlinked from any dir.
+
+* port systemctl, busctl, … over to format-table.[ch]'s table formatters
+
+* pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
+
+* add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
+
+* SuccessExitStatus= and friends should probably also accept symbolic exit
+ codes names, i.e. error codes from the list maintained in exit-codes.[ch]
+
+* introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
+ files and directories that are left writable for a unit, and which are
+ removed after the unit goes down again. A bit like --ephemeral for
+ systemd-nspawn but for system services. If used together with RootImage= this
+ should reflink the image file itself.
+
+ Related: add Ephemeral=<path1> <path2> … which would allow marking
+ specific paths only like this.
+
+* add CopyFile= or so as unit file setting that may be used to copy files or
+ directory trees from the host to te services RootImage= and RootDirectory=
+ environment. Which we can use for /etc/machine-id and in particular
+ /etc/resolv.conf. Should be smart and do something useful on read-only
+ images, for example fallback to read-only bind mounting the file instead.
+
+* nspawn's console TTY should be allocated from within the container, not
+ mounted in from the outside
+
+* show invocation ID in systemd-run output
+
+* bypass SIGTERM state in unit files if KillSignal is SIGKILL
+
+* tree-wide: ensure we always block the signals we hook into with
+ sd_event_add_signal() first
+
+* add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
+ and so on, which would mean we could report errors and such.
+
+* teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
+ project quota
+
+* introduce DefaultSlice= or so in system.conf that allows changing where we
+ place our units by default, i.e. change system.slice to something
+ else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
+ be moved somewhere else too. Finally machined and logind should get similar
+ options so that it is possible to move user session scopes and machines to a
+ different slice too by default. Usecase: people who want to put resources on
+ the entire system, with the exception of one specific service. See:
+ https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
+
+* maybe rework get_user_creds() to query the user database if $SHELL is used
+ for root, but only then.
+
+* be stricter with fds we receive for the fdstore: close them asynchronously
+
+* calenderspec: add support for week numbers and day numbers within a
+ year. This would allow us to define "bi-weekly" triggers safely.
+
+* sd-bus: add vtable flag, that may be used to request client creds implicitly
+ and asynchronously before dispatching the operation
+
+* make use of ethtool veth peer info in machined, for automatically finding out
+ host-side interface pointing to the container.
+
+* add some special mode to LogsDirectory=/StateDirectory=… that allows
+ declaring these directories without necessarily pulling in deps for them, or
+ creating them when starting up. That way, we could declare that
+ systemd-journald writes to /var/log/journal, which could be useful when we
+ doing disk usage calculations and so on.
+
+* taint systemd if there are fewer than 65536 users assigned (userns) to the system.
+
+* deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
+
+* add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
+ the runtime dir as we maintain for the fdstore: i.e. keep it around as long
+ as the unit is running or has a job queued.
+
+* support projid-based quota in machinectl for containers
+
+* Add NetworkNamespacePath= to specify a path to a network namespace
+
+* maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
+ introduced) as the RTC epoch, instead of the mtime of NEWS.
+
+* add a way to lock down cgroup migration: a boolean, which when set for a unit
+ makes sure the processes in it can never migrate out of it
+
+* blog about fd store and restartable services
+
+* document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
+
+* rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
+ magic meaning and is no longer upgraded to something else if set explicitly.
+
+* in the long run: permit a system with /etc/machine-id linked to /dev/null, to
+ make it lose its identity, i.e. be anonymous. For this we'd have to patch
+ through the whole tree to make all code deal with the case where no machine
+ ID is available.
+
+* optionally, collect cgroup resource data, and store it in per-unit RRD files,
+ suitable for processing with rrdtool. Add bus API to access this data, and
+ possibly implement a CPULoad property based on it.
+
+* beef up pam_systemd to take unit file settings such as cgroups properties as
+ parameters
+
+* maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
+ the quota of a the user indicated in User= via unit file settings, like the
+ other resource management concepts. Would mix nicely with DynamicUser=1. Or
+ alternatively, do this with projids, so that we can also cover services
+ running as root. Quota should probably cover all the special dirs such as
+ StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
+ is set, plus the whole disk space any image configured with RootImage=.
+
+* In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
+ disks to see if the UID is already in use.
+
+* add "systemctl wait" or so, which does what "systemd-run --wait" does, but
+ for all units. It should be both a way to pin units into memory as well as a
+ wait to retrieve their exit data.
+
+* expose IO accounting data on the bus, show it in systemd-run --wait and log
+ about it in the resource log message
+
+* add "systemctl purge" for flushing out configuration, state, logs, ... of a
+ unit when it is stopped
+
+* show whether a service has out-of-date configuration in "systemctl status" by
+ using mtime data of ConfigurationDirectory=.
+
+* replace all remaining uses of fgets() + LINE_MAX by read_line()
+
+* Add AddUser= setting to unit files, similar to DynamicUser=1 which however
+ creates a static, persistent user rather than a dynamic, transient user. We
+ can leverage code from sysusers.d for this.
+
+* add some optional flag to ReadWritePaths= and friends, that has the effect
+ that we create the dir in question when the service is started. Example:
+
+ ReadWritePaths=:/var/lib/foobar
+
+* maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
+ the sd-journal logging socket, and, if the timeout is set to 0, sets
+ O_NONBLOCK on it. That way people can control if and when to block for
+ logging.
+
+* hostnamed: populate form factor data from a new hwdb database, so that old
+ yogas can be recognized as "convertible" too, even if they predate the DMI
+ "convertible" form factor
+
+* Maybe add a small tool invoked early at boot, that adds in or resizes
+ partitions automatically, to be used when the media used is actually larger
+ than the image written onto it is.
+
+* Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
+ after all. Be strict however, only support the equivalent of nspawn's
+ --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
+ as MAINPID.
+
+* Add ExecMonitor= setting. May be used multiple times. Forks off a process in
+ the service cgroup, which is supposed to monitor the service, and when it
+ exits the service is considered failed by its monitor.
+
+* track the per-service PAM process properly (i.e. as an additional control
+ process), so that it may be queried on the bus and everything.
+
+* add a new "debug" job mode, that is propagated to unit_start() and for
+ services results in two things: we raise SIGSTOP right before invoking
+ execve() and turn off watchdog support. Then, use that to implement
+ "systemd-gdb" for attaching to the start-up of any system service in its
+ natural habitat.
+
+* maybe introduce gpt auto discovery for /var/tmp?
+
+* maybe add gpt-partition-based user management: each user gets his own
+ LUKS-encrypted GPT partition with a new GPT type. A small nss module
+ enumerates users via udev partition enumeration. UIDs are assigned in a fixed
+ way: the partition index is added as offset to some fixed base uid. User name
+ is stored in GPT partition name. A PAM module authenticates the user via the
+ LUKS partition password. Benefits: strong per-user security, compatibility
+ with stateless/read-only/verity-enabled root. (other idea: do this based on
+ loopback files in /home, without GPT involvement)
+
+* gpt-auto logic: introduce support for discovering /var matching an image. For
+ that, use a partition type UUID that is hashed from the OS name (as encoded
+ in /etc/os-release), the architecture, and 4 new bits from the gpt flags
+ field of the root partition. This way can easily support multiple OS
+ installations on the same GPT partition table, without problems with
+ unmatched /var partitions.
+
+* gpt-auto logic: related to the above, maybe support a "secondary" root
+ partition, that is mounted to / and is writable, and where the actual root's
+ /usr is mounted into.
+
+* gpt-auto logic: support encrypted swap, add kernel cmdline option to force it, and honour a gpt bit about it, plus maybe a configuration file
+
+* drop nss-myhostname in favour of nss-resolve?
+
+* add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
+ then use that for the setting used in user@.service. It should be understood
+ relative to the configured default value.
+
+* in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
+
+* enable LockMLOCK to take a percentage value relative to physical memory
+
+* Permit masking specific netlink APIs with RestrictAddressFamily=
+
+* nspawn: support that /proc, /sys/, /dev are pre-mounted
+
+* define gpt header bits to select volatility mode
+
+* ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
+
+* ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
+
+* ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
+
+* ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
+
+* ProtectKeyRing= to take keyring calls away
+
+* RemoveKeyRing= to remove all keyring entries of the specified user
+
+* ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
+ on PID 1 with the relevant signals, and makes relevant files in /sys and
+ /proc (such as the sysrq stuff) unavailable
+
+* make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
+
+* journalctl: make sure -f ends when the container indicated by -M terminates
+
+* mount: automatically search for "main" partition of an image has multiple
+ partitions
+
+* expose the "privileged" flag of ExecCommand on the bus, and open it up to
+ transient units
+
+* in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
+ find a way to map the User=/Group= of the service to the right name. This way
+ a user/group for a service only has to exist on the host for the right
+ mapping to work.
+
+* add bus API for creating unit files in /etc, reusing the code for transient units
+
+* add bus API to remove unit files from /etc
+
+* add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
+
+* rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
+ kernel doesn't support linkat() that replaces existing files, currently)
+
+* transient units: don't bother with actually setting unit properties, we
+ reload the unit file anyway
+
+* journald: sigbus API via a signal-handler safe function that people may call
+ from the SIGBUS handler
+
+* optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
+
+* resolved: when routing queries, make sure only look for the *longest* suffix...
+
+* delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
+ in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
+
+* cache sd_event_now() result from before the first iteration...
+
+* add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
+
+* PID1: find a way how we can reload unit file configuration for
+ specific units only, without reloading the whole of systemd
+
+* add an explicit parser for LimitRTPRIO= that verifies
+ the specified range and generates sane error messages for incorrect
+ specifications.
+
+* when we detect that there are waiting jobs but no running jobs, do something
+
+* push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
+
+* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
+
+* there's probably something wrong with having user mounts below /sys,
+ as we have for debugfs. for exmaple, src/core/mount.c handles mounts
+ prefixed with /sys generally special.
+ http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
+
+* fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
+
+* docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
+
+* add a job mode that will fail if a transaction would mean stopping
+ running units. Use this in timedated to manage the NTP service
+ state.
+ http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
+
+* The udev blkid built-in should expose a property that reflects
+ whether media was sensed in USB CF/SD card readers. This should then
+ be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
+ picked up by systemd unless they contain a medium. This would mirror
+ the behaviour we already have for CD drives.
+
+* networkd/udev: implement SR_IOV configuration in .link files:
+ http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
+
+* hostnamectl: show root image uuid
+
+* Find a solution for SMACK capabilities stuff:
+ http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
+
+* "systemctl preset-all" should probably order the unit files it
+ operates on lexicographically before starting to work, in order to
+ ensure deterministic behaviour if two unit files conflict (like DMs
+ do, for example)
+
+* synchronize console access with BSD locks:
+ http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
+
+* as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
+ http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
+
+* in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
+
+* figure out when we can use the coarse timers
+
+* add "systemctl start -v foobar.service" that shows logs of a service
+ while the start command runs. This is non-trivial to do without
+ races though, since we should flush out all journal messages before
+ returning from the "systemctl stop".
+
+* firstboot: make it useful to be run immediately after yum --installroot to set up a machine. (most specifically, make --copy-root-password work even if /etc/passwd already exists
+
+* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
+
+* consider showing the unit names during boot up in the status output, not just the unit descriptions
+
+* maybe allow timer units with an empty Units= setting, so that they
+ can be used for resuming the system but nothing else.
+
+* what to do about udev db binary stability for apps? (raw access is not an option)
+
+* man: maybe use the word "inspect" rather than "introspect"?
+
+* systemctl: if some operation fails, show log output?
+
+* systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
+ Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
+
+* exponential backoff in timesyncd when we cannot reach a server
+
+* timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
+
+* merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
+
+* systemd.show_status= should probably have a mode where only failed
+ units are shown.
+
+* add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
+ (throughout the codebase, not only PID1)
+
+* resolved:
+ - mDNS/DNS-SD
+ - service registration
+ - service/domain/types browsing
+ - avahi compat
+ - DNS-SD service registration from socket units
+ - resolved should optionally register additional per-interface LLMNR
+ names, so that for the container case we can establish the same name
+ (maybe "host") for referencing the server, everywhere.
+ - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
+ - hook up resolved with machined-based address resolution
+
+* refcounting in sd-resolve is borked
+
+* Add a new verb "systemctl top"
+
+* add new gpt type for btrfs volumes
+
+* support empty /etc boots nicely:
+ - nspawn/gpt-generator: introduce new gpt partition type for /usr
+
+* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
+
+* a way for container managers to turn off getty starting via $container_headless= or so...
+
+* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
+
+* For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
+ they run added to the initial transaction and thus confuse Type=idle.
+
+* add bus api to query unit file's X fields.
+
+* gpt-auto-generator:
+ - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
+ - Make /home automount rather than mount?
+
+* add generator that pulls in systemd-network from containers when
+ CAP_NET_ADMIN is set, more than the loopback device is defined, even
+ when it is otherwise off
+
+* MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
+
+* implement Distribute= in socket units to allow running multiple
+ service instances processing the listening socket, and open this up
+ for ReusePort=
+
+* socket units: support creating sockets in different namespace,
+ opening it up for JoinsNamespaceOf=. This would require to fork off
+ a tiny process that joins the namespace and creates/binds the socket
+ and passes this back to PID1 via SCM_RIGHTS. This also could be used
+ to allow Chown/chgrp on sockets without requiring NSS in PID 1.
+
+* introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
+ $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
+ should SIGSTOP all unit processes in a loop until all processes of
+ it are fully stopped. This can later be used for app management by
+ desktop UIs such as gnome-shell to freeze apps that are not visible
+ on screen, not unlike how job control works on the shell
+
+* cgroups:
+ - implement per-slice CPUFairScheduling=1 switch
+ - introduce high-level settings for RT budget, swappiness
+ - how to reset dynamically changed unit cgroup attributes sanely?
+ - when reloading configuration, apply new cgroup configuration
+ - when recursively showing the cgroup hierarchy, optionally also show
+ the hierarchies of child processes
+
+* transient units:
+ - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
+
+* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
+
+* when we detect low battery and no AC on boot, show pretty splash and refuse boot
+
+* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
+
+* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
+
+* rfkill,backlight: we probably should run the load tools inside of the udev rules so that the state is properly initialized by the time other software sees it
+
+* After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
+
+* If we try to find a unit via a dangling symlink, generate a clean
+ error. Currently, we just ignore it and read the unit from the search
+ path anyway.
+
+* refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
+
+* man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
+
+* load .d/*.conf dropins for device units
+
+* allow implementation of InaccessibleDirectories=/ plus
+ ReadOnlyDirectories=... for whitelisting files for a service.
+
+* sd-bus:
+ - EBADSLT handling
+ - GetAllProperties() on a non-existing object does not result in a failure currently
+ - port to sd-resolve for connecting to TCP dbus servers
+ - see if we can introduce a new sd_bus_get_owner_machine_id() call to retrieve the machine ID of the machine of the bus itself
+ - see if we can drop more message validation on the sending side
+ - add API to clone sd_bus_message objects
+ - longer term: priority inheritance
+ - dbus spec updates:
+ - NameLost/NameAcquired obsolete
+ - GVariant
+ - path escaping
+ - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
+
+* sd-event
+ - allow multiple signal handlers per signal?
+ - document chaining of signal handler for SIGCHLD and child handlers
+ - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
+ - generate a failure of a default event loop is executed out-of-thread
+
+* investigate endianness issues of UUID vs. GUID
+
+* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
+ should be able to safely try another attempt when the bus call LoadUnit() is invoked.
+
+* add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
+
+* add a pam module that on password changes updates any LUKS slot where the password matches
+
+* test/:
+ - add unit tests for config_parse_device_allow()
+
+* seems that when we follow symlinks to units we prefer the symlink
+ destination path over /etc and /usr. We should not do that. Instead
+ /etc should always override /run+/usr and also any symlink
+ destination.
+
+* when isolating, try to figure out a way how we implicitly can order
+ all units we stop before the isolating unit...
+
+* teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
+
+* BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
+ that the boot loader should be installed to the ESP. Define a way
+ how an installer can figure out whether a BLS compliant boot loader
+ is installed.
+
+* think about requeuing jobs when daemon-reload is issued? usecase:
+ the initrd issues a reload after fstab from the host is accessible
+ and we might want to requeue the mounts local-fs acquired through
+ that automatically.
+
+* systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
+
+* remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
+
+* shutdown logging: store to EFI var, and store to USB stick?
+
+* merge unit_kill_common() and unit_kill_context()
+
+* introduce ExecCondition= in services
+
+* EFI:
+ - honor language efi variables for default language selection (if there are any?)
+ - honor timezone efi variables for default timezone selection (if there are any?)
+ - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
+
+* maybe do not install getty@tty1.service symlink in /etc but in /usr?
+
+* print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
+
+* mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
+
+* logind:
+ - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
+ - logind: wakelock/opportunistic suspend support
+ - Add pretty name for seats in logind
+ - logind: allow showing logout dialog from system?
+ - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
+ - if pam_systemd is invoked by su from a process that is outside of a
+ any session we should probably just become a NOP, since that's
+ usually not a real user session but just some system code that just
+ needs setuid().
+ - logind: make the Suspend()/Hibernate() bus calls wait for the for
+ the job to be completed. before returning, so that clients can wait
+ for "systemctl suspend" to finish to know when the suspending is
+ complete.
+ - logind: when the power button is pressed short, just popup a
+ logout dialog. If it is pressed for 1s, do the usual
+ shutdown. Inspiration are Macs here.
+ - expose "Locked" property on logind sesison objects
+ - maybe allow configuration of the StopTimeout for session scopes
+ - rename session scope so that it includes the UID. THat way
+ the session scope can be arranged freely in slices and we don't have
+ make assumptions about their slice anymore.
+ - follow PropertiesChanged state more closely, to deal with quick logouts and
+ relogins
+
+* exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
+
+* journal:
+ - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
+ - import and delete pstore filesystem content at startup
+ - journald: also get thread ID from client, plus thread name
+ - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
+ - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
+ - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
+ - declare the local journal protocol stable in the wiki interface chart
+ - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
+ - journald: when dropping msgs due to ratelimit make sure to write
+ "dropped %u messages" not only when we are about to print the next
+ message that works, but alraedy after a short tiemout
+ - check if we can make journalctl by default use --follow mode inside of less if called without args?
+ - maybe add API to send pairs of iovecs via sd_journal_send
+ - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
+ - journactl: support negative filtering, i.e. FOOBAR!="waldo",
+ and !FOOBAR for events without FOOBAR.
+ - journal: store timestamp of journal_file_set_offline() int he header,
+ so it is possible to display when the file was last synced.
+ - journal-send.c, log.c: when the log socket is clogged, and we drop, count this and write a message about this when it gets unclogged again.
+ - journal: find a way to allow dropping history early, based on priority, other rules
+ - journal: When used on NFS, check payload hashes
+ - journald: add kernel cmdline option to disable ratelimiting for debug purposes
+ - refuse taking lower-case variable names in sd_journal_send() and friends.
+ - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
+ - journal: deal nicely with byte-by-byte copied files, especially regards header
+ - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
+ - Replace utmp, wtmp, btmp, and lastlog completely with journal
+ - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
+ - when a kernel driver logs in a tight loop, we should ratelimit that too.
+ - journald: optionally, log debug messages to /run but everything else to /var
+ - journald: when we drop syslog messages because the syslog socket is
+ full, make sure to write how many messages are lost as first thing
+ to syslog when it works again.
+ - change systemd-journal-flush into a service that stays around during
+ boot, and causes the journal to be moved back to /run on shutdown,
+ so that we do not keep /var busy. This needs to happen synchronously,
+ hence doing this via signals is not going to work.
+ - optionally support running journald from the command line for testing purposes in external projects
+ - journald: allow per-priority and per-service retention times when rotating/vacuuming
+ - journald: make use of uid-range.h to managed uid ranges to split
+ journals in.
+ - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
+ - improve journalctl performance by loading journal files
+ lazily. Encode just enough information in the file name, so that we
+ do not have to open it to know that it is not interesting for us, for
+ the most common operations.
+ - man: document that corrupted journal files is nothing to act on
+ - rework journald sigbus stuff to use mutex
+ - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
+ services that run under their own user ids, and use User= (but only
+ in a world where userns is ubiquitous since otherwise we cannot
+ invoke those daemons on the host AND in a container anymore). Also,
+ if LimitNPROC= is used without User= we should warn and refuse
+ operation.
+ - journalctl --verify: don't show files that are currently being
+ written to as FAIL, but instead show that their are being written to.
+ - add journalctl -H that talks via ssh to a remote peer and passes through
+ binary logs data
+ - add a version of --merge which also merges /var/log/journal/remote
+ - journalctl: -m should access container journals directly by enumerating
+ them via machined, and also watch containers coming and going.
+ Benefit: nspawn --ephemeral would start working nicely with the journal.
+ - assign MESSAGE_ID to log messages about failed services
+
+* add a test if all entries in the catalog are properly formatted.
+ (Adding dashes in a catalog entry currently results in the catalog entry
+ being silently skipped. journalctl --update-catalog must warn about this,
+ and we should also have a unit test to check that all our message are OK.)
+
+* document:
+ - document that deps in [Unit] sections ignore Alias= fields in
+ [Install] units of other units, unless those units are disabled
+ - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
+ - document that service reload may be implemented as service reexec
+ - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
+ - document systemd-journal-flush.service properly
+ - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
+ - man: document the very specific env the shutdown drop-in tools live in
+ - man: add more examples to man pages
+ - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
+
+* systemctl:
+ - add systemctl switch to dump transaction without executing it
+ - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
+ - "systemctl disable" on a static unit prints no message and does
+ nothing. "systemctl enable" does nothing, and gives a bad message
+ about it. Should fix both to print nice actionable messages.
+ - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
+ - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
+ - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
+ - systemctl: "Journal has been rotated since unit was started." message is misleading
+ - systemctl status output should include list of triggering units and their status
+
+* unit install:
+ - "systemctl mask" should find all names by which a unit is accessible
+ (i.e. by scanning for symlinks to it) and link them all to /dev/null
+
+* timer units:
+ - timer units should get the ability to trigger when:
+ o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
+ o DST changes
+ o timezone changes
+ - Modulate timer frequency based on battery state
+
+* add libsystemd-password or so to query passwords during boot using the password agent logic
+
+* clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
+
+* on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
+
+* make repeated alt-ctrl-del presses printing a dump
+
+* hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
+
+* currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
+
+* nspawn:
+ - emulate /dev/kmsg using CUSE and turn off the syslog syscall
+ with seccomp. That should provide us with a useful log buffer that
+ systemd can log to during early boot, and disconnect container logs
+ from the kernel's logs.
+ - as soon as networkd has a bus interface, hook up --network-interface=,
+ --network-bridge= with networkd, to trigger netdev creation should an
+ interface be missing
+ - a nice way to boot up without machine id set, so that it is set at boot
+ automatically for supporting --ephemeral. Maybe hash the host machine id
+ together with the machine name to generate the machine id for the container
+ - fix logic always print a final newline on output.
+ https://github.com/systemd/systemd/pull/272#issuecomment-113153176
+ - should optionally support receiving WATCHDOG=1 messages from its payload
+ PID 1...
+ - optionally automatically add FORWARD rules to iptables whenever nspawn is
+ running, remove them when shut down.
+
+* dissect
+ - refuse mounting over a mount point
+ - automatically discover .roothash files in dissect, similarly to nspawn
+
+* machined:
+ - add an API so that libvirt-lxc can inform us about network interfaces being
+ removed or added to an existing machine
+ - "machinectl migrate" or similar to copy a container from or to a
+ difference host, via ssh
+ - introduce systemd-nspawn-ephemeral@.service, and hook it into
+ "machinectl start" with a new --ephemeral switch
+ - "machinectl status" should also show internal logs of the container in
+ question
+ - "machinectl history"
+ - "machinectl diff"
+ - "machinectl commit" that takes a writable snapshot of a tree, invokes a
+ shell in it, and marks it read-only after use
+
+* cryptsetup:
+ - cryptsetup-generator: allow specification of passwords in crypttab itself
+ - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
+
+* hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
+ https://bugs.freedesktop.org/show_bug.cgi?id=54712
+
+* add a dependency on standard-conf.xml and other included files to man pages
+
+* MountFlags=shared acts as MountFlags=slave right now.
+
+* properly handle loop back mounts via fstab, especially regards to fsck/passno
+
+* initialize the hostname from the fs label of /, if /etc/hostname does not exist?
+
+* udev:
+ - move to LGPL
+ - kill scsi_id
+ - add trigger --subsystem-match=usb/usb_device device
+ - reimport udev db after MOVE events for devices without dev_t
+
+* There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
+
+* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
+
+* coredump:
+ - save coredump in Windows/Mozilla minidump format
+ - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
+
+* support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
+
+* default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
+
+* be able to specify a forced restart of service A where service B depends on, in case B
+ needs to be auto-respawned?
+
+* tmpfiles:
+ - apply "x" on "D" too (see patch from William Douglas)
+ - replace F with f+.
+ - instead of ignoring unknown fields, reject them.
+ - creating new directories/subvolumes/fifos/device nodes
+ should not follow symlinks. None of the other adjustment or creation
+ calls follow symlinks.
+
+* make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
+
+* verify that the AF_UNIX sockets of a service in the fs still exist
+ when we start a service in order to avoid confusion when a user
+ assumes starting a service is enough to make it accessible
+
+* Make it possible to set the keymap independently from the font on
+ the kernel cmdline. Right now setting one resets also the other.
+
+* and a dbus call to generate target from current state
+
+* write blog stories about:
+ - hwdb: what belongs into it, lsusb
+ - enabling dbus services
+ - how to make changes to sysctl and sysfs attributes
+ - remote access
+ - how to pass throw-away units to systemd, or dynamically change properties of existing units
+ - testing with Harald's awesome test kit
+ - auto-restart
+ - how to develop against journal browsing APIs
+ - the journal HTTP iface
+ - non-cgroup resource management
+ - dynamic resource management with cgroups
+ - refreshed, longer missions statement
+ - calendar time events
+ - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
+ - how to create your own target
+ - instantiated apache, dovecot and so on
+ - hooking a script into various stages of shutdown/rearly booot
+
+* investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
+
+* dot output for --test showing the 'initial transaction'
+
+* pid1:
+ - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
+ log both units as UNIT=, so that journalctl -u triggers on both.
+ - generate better errors when people try to set transient properties
+ that are not supported...
+ http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
+ - maybe introduce WantsMountsFor=? Usecase:
+ http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
+ - recreate systemd's D-Bus private socket file on SIGUSR2
+ - move PAM code into its own binary
+ - when we automatically restart a service, ensure we restart its rdeps, too.
+ - hide PAM options in fragment parser when compile time disabled
+ - Support --test based on current system state
+ - If we show an error about a unit (such as not showing up) and it has no Description string, then show a description string generated form the reverse of unit_name_mangle().
+ - after deserializing sockets in socket.c we should reapply sockopts and things
+ - drop PID 1 reloading, only do reexecing (difficult: Reload()
+ currently is properly synchronous, Reexec() is weird, because we
+ cannot delay the response properly until we are back, so instead of
+ being properly synchronous we just keep open the fd and close it
+ when done. That means clients do not get a successful method reply,
+ but much rather a disconnect on success.
+ - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
+ - when a bus name of a service disappears from the bus make sure to queue further activation requests
+
+* unit files:
+ - allow port=0 in .socket units
+ - maybe introduce ExecRestartPre=
+ - add ReloadSignal= for configuring a reload signal to use
+ - implement Register= switch in .socket units to enable registration
+ in Avahi, RPC and other socket registration services.
+ - allow Type=simple with PIDFile=
+ https://bugzilla.redhat.com/show_bug.cgi?id=723942
+ - allow writing multiple conditions in unit files on one line
+ - load-fragment: when loading a unit file via a chain of symlinks
+ verify that it is not masked via any of the names traversed.
+ - introduce Type=pid-file
+ - introduce mix of BindTo and Requisite
+ - add a concept of RemainAfterExit= to scope units
+ - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
+
+* udev-link-config:
+ - Make sure ID_PATH is always exported and complete for
+ network devices where possible, so we can safely rely
+ on Path= matching
+ - check MTUBytes parsing (expecting size_t but we are using unsigned)
+
+* sd-rtnl:
+ - add support for more attribute types
+ - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
+
+* networkd:
+ - add more keys to [Route] and [Address] sections
+ - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
+ - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
+ - add reduced [Link] support to .network files
+ - add Scope= parsing option for [Network]
+ - properly handle routerless dhcp leases
+ - work with non-Ethernet devices
+ - add support for more bond options
+ - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
+ - the DHCP lease data (such as NTP/DNS) is still made available when
+ a carrier is lost on a link. It should be removed instantly.
+ - expose in the API the following bits:
+ - option 15, domain name and/or option 119, search list
+ - option 12, host name and/or option 81, fqdn
+ - option 123, 144, geolocation
+ - option 252, configure http proxy (PAC/wpad)
+ - provide a way to define a per-network interface default metric value
+ for all routes to it. possibly a second default for DHCP routes.
+ - allow Name= to be specified repeatedly in the [Match] section. Maybe also
+ support Name=foo*|bar*|baz ?
+ - duplicate address check for static IPs (like ARPCHECK in network-scripts)
+ - allow DUID/IAID to be customized, see issue #394.
+ - whenever uplink info changes, make DHCP server send out FORCERENEW
+
+* networkd-wait-online:
+ - make operstates to wait for configurable?
+
+* dhcp:
+ - figure out how much we can increase Maximum Message Size
+
+* dhcp6:
+ - add functions to set previously stored IPv6 addresses on startup and get
+ them at shutdown; store them in client->ia_na
+ - write more test cases
+ - implement reconfigure support, see 5.3., 15.11. and 22.20.
+ - implement support for temporary adressess (IA_TA)
+ - implement dhcpv6 authentication
+ - investigate the usefulness of Confirm messages; i.e. are there any
+ situations where the link changes without any loss in carrier detection
+ or interface down
+ - some servers don't do rapid commit without a filled in IA_NA, verify
+ this behavior
+ - RouteTable= ?
+
+External:
+
+* dbus:
+ - natively watch for dbus-*.service symlinks (PENDING)
+ - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
+
+* fix alsa mixer restore to not print error when no config is stored
+
+* make cryptsetup lower --iter-time
+
+* patch kernel for xattr support in /dev, /proc/, /sys?
+
+* kernel: add device_type = "fb", "fbcon" to class "graphics"
+
+* /usr/bin/service should actually show the new command line
+
+* fedora: suggest auto-restart on failure, but not on success and not on coredump. also, ask people to think about changing the start limit logic. Also point people to RestartPreventExitStatus=, SuccessExitStatus=
+
+* fedora: F20: go timer units all the way, leave cron.daily for cron
+
+* neither pkexec nor sudo initialize environ[] from the PAM environment?
+
+* fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
+
+* register catalog database signature as file magic
+
+* zsh shell completion:
+ - <command> <verb> -<TAB> should complete options, but currently does not
+ - systemctl add-wants,add-requires
+
+
+Regularly:
+
+* look for close() vs. close_nointr() vs. close_nointr_nofail()
+
+* check for strerror(r) instead of strerror(-r)
+
+* pahole
+
+* set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
+
+* use secure_getenv() instead of getenv() where appropriate
