2 * check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar
4 * swap units that are activated by one name but shown in the kernel under another are semi-broken
6 * make anaconda write timeout=0 for encrypted devices
8 * Dangling symlinks of .automount unit files in .wants/ directories, set up
9 automount points even when the original .automount file did not exist
10 anymore. Only the .mount unit was still around.
12 * make polkit checks async
14 * properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
22 * refuse instantiation of proc.mount and mount units for all other API fs
24 * "systemctl disable" on a static unit prints no message and does
25 nothing. "systemctl enable" does nothing, and gives a bad message
26 about it. Should fix both to print nice actionable messages.
28 * fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
29 https://bugzilla.redhat.com/show_bug.cgi?id=812826
31 * add "loginctl unlock-sessions" as counterpart for "loginctl lock-sessions"
33 * extend cgroup attr dbus calls to optionally make changes persistent, and retrieve current kernel values
35 * support high-level cgroup setting syntax in systemctl. Example: "systemctl set-cgroup-attr MemoryLimit 5K"
37 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
39 * kernel cmdline switch to turn off predictable network interface names
41 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
43 * udev: remove all (misguided from day 1) userspace firmware_class handling
45 * logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
47 * service: when killing a service with SIGKILL always kill all processes, even if for SIGTERM we only killed the main process
49 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
51 * DeviceAllow/DeviceDeny: disallow everything by default, but whitelist /dev/zero, /dev/null and friends
53 * service: watchdog logic: for testing purposes allow ping, but do not require pong
55 * journald: when dropping msgs due to ratelimit make sure to write
56 "dropped %u messages" not only when we are about to print the next
57 message that works, but alraedy after a short tiemout
59 * journald: also get thread ID from client, plus thread name
61 * check if we can make journalctl by default use --follow mode inside of less if called without args?
63 * Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
65 * journal is not closed properly at shutdown when run in a container?
67 * journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
69 * When shutdown.target is queued begin with an asynchronous sync()?
71 * add API to close/reopen/get fd for journal client fd in libsystemd-journal.
73 * maybe add API to send pairs of iovecs via sd_journal_send
75 * fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
77 * declare the local journal protocol stable in the wiki interface chart
79 * journal: reuse XZ context
81 * sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
83 * introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
85 * timer units should get the ability to trigger when:
86 - CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
89 * update the kernel's TZ (sys_tz) when DST changes
91 * sync down the system time to the RTC when:
92 - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
93 - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
94 This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
95 mode, it will never touch the RTC if the no reliable time source is active or the
96 user did not request anything like it.
98 * When we begin with system shutdown all kind of suspend/hibernation should be prohibited until shutdown/reboot
100 * When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
103 - implement conditional properties (dmi matches)
104 - hwdb --filter=ID_DRIVE_*
105 - find out what to do for blockdevs and skipping scsi modaliases
106 - move writing code to src/libudev/libudev-hwdb-private.c
108 * if booted in "quiet" mode, and an error happens, turn on status output again, so that the emergency mode isn't totally surprising
110 * localectl: add listing support for X11 keymaps, by parsing /usr/share/X11/xkb/rules/xorg.lst
112 * libunwind support for coredump pattern hook, and includes this in
113 the message for coredumps. After all, libunwind is now capable to
114 unwind coredumps since a few weeks ago. This probably requires that
115 we have nice support for multi-line messages on display in logs-show.c.
117 * figure out relation of --all and --full in the various tools
119 * journal: when writing journal auto-rotate if time jumps backwards
121 * introduce new "journal" group in place of adm? introduce groups for the various mini daemons?
123 * journal: add a setgid "adm" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
125 * journactl: support negative filtering, i.e. FOOBAR!="waldo",
126 and !FOOBAR for events without FOOBAR.
128 * print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
130 * add libsystemd-password or so to query passwords during boot using the password agent logic
132 * journal: when rotating, copy over old acls/access mode
134 * journal: document why we do not give ownership to journal files to the user that created them but use FS ACLs for that
136 * journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
138 * journal: when we haven't written anything in a while, sync to disk and mark file as offline, in order to be more often than not in a clean state
140 * 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.
142 * 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().
144 * fedup: add --unit to systemctl switch-root somehow
145 * fedup: don't delete initrd on switch-root
148 * journal: find a way to allow dropping history early, based on priority, other rules
150 * journal: When used on NFS, check payload hashes
152 * journal: When used on NFS make sure wake up sd_journal_wait() every 2s, to handle missing inotify
154 * document that people can use file system ACLs to manage access to journal files, with example
156 * timedated: export boolean that clarifies whether NTP is even available
158 * timedated: refuse time changes when NTP is on
160 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
162 * document unit_name_mangle()
164 * add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
166 * introduce generic AUGMENT_PID=, AUGMENT_DEVICE= fields
168 * deal with sendmail/postfix exclusivity
170 * systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
172 * systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
174 * on shutdown: move utmp, wall, audit logic all into PID 1 itself, get rid of systemd-update-utmp-runlevel
176 * add "provisioning" instructions to setup an empty /etc + /var
177 - used to setup a new container from a shared /usr
178 - superset of tmpfiles model
179 - instructions shipped by packages and stored in /usr/lib/
180 - compose /etc/passwd and /etc/group, copy files
181 - able to create uid + gid used by packages, for file ownership
183 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
184 waiting for the timeout
186 * high level net_prio setting in execution context
188 * Introduce journalctl -b <nr> to show journal messages of a previous boot
190 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
192 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
194 * WorkingDirectory: support env var replacements like in ExecStart= so that people can use $HOME
196 * refuse boot if /etc/machine-id is not useful (or set taint?)
198 * nspawn: consider changing users for -u with su, so that NSS resolving works correctly
200 * nspawn: implement personality changes a la linux32(8)
202 * cryptsetup-generator: warn if the password files are world-readable
204 * cryptsetup-generator: add RequiresMountsFor= to cryptseup service files referencing a file, similar for devices
206 * cryptsetup-generator: allow specification of passwords in crypttab itself
208 * document that deps in [Unit] sections ignore Alias= fileds in
209 [Install] units of other units, unless those units are disabled
211 * systemctl: when powering down/suspending check for inhibitors, and warn.
213 * instantiated [Install] for target units
214 https://bugs.freedesktop.org/show_bug.cgi?id=54377
216 * move debug shell to tty6 and make sure this doesn't break the gettys on tty6
218 * move cryptsetup key caching into kernel keyctl?
219 https://bugs.freedesktop.org/show_bug.cgi?id=54982
221 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
222 https://bugs.freedesktop.org/show_bug.cgi?id=54712
224 * after deserializing sockets in socket.c we should reapply sockopts and things
226 * make timer units go away after they elapsed
228 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
229 (network and remote-fs on shutdown)
231 * come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
233 * journald: add kernel cmdline option to disable ratelimiting for debug purposes
235 * move PID 1 segfaults to /var/lib/systemd/coredump?
237 * Document word splitting syntax for ExecStart= and friends
239 * create /sbin/init symlinks from the build system
241 * Query Paul Moore about relabelling socket fds while they are open
243 * journald: check whether it is OK if the client can still modify delivered journal entries
245 * journal live copy, based on libneon (client) and libmicrohttpd
247 * system-wide seccomp filter
249 * system.conf should have controls for cgroups
251 * bind mount read-only the cgroup tree higher than nspawn
253 * allow writing multiple conditions in unit files on one line
255 * explore multiple service instances per listening socket idea
257 * testing tool for socket activation: some binary that listens on a socket and passes it on using the usual socket activation protocol to some server.
259 * shutdown: don't read-only mount anything when running in container
261 * nspawn: --read-only is not applied recursively to submounts
263 * MountFlags=shared acts as MountFlags=slave right now.
265 * ReadOnlyDirectories= is not applied recursively to submounts
267 * drop PID 1 reloading, only do reexecing (difficult: Reload()
268 currently is properly synchronous, Reexec() is weird, because we
269 can't delay the response properly until we are back, so instead of
270 being properly synchronous we just keep open the fd and close it
271 when done. That means clients don't get a successful method reply,
272 but much rather a disconnect on success.
274 * document that service reload may be implemented as service reexec
276 * remember which condition failed for services, not just the fact that something failed
278 * use opterr = 0 for all getopt tools
280 * properly handle loop back mounts via fstab, especially regards to fsck/passno
282 * allow services with no ExecStart= but with an ExecStop=
284 * add proper journal support to "systemctl --user status ..."
286 * add _SYSTEMD_USER_UNIT= field to journal entries
288 * dracut-shutdown needs to be ordered before unmounting /boot
290 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
292 * rename "userspace" to "core-os"
294 * systemctl: "Journal has been rotated since unit was started." message is misleading
296 * syscall filter: add knowledge about compat syscalls
298 * syscall filter: don't enforce no new privs?
300 * syscall filter: option to return EPERM rather than SIGSYS?
302 * syscall filter: port to libseccomp
304 * logind: wakelock/opportunistic suspend support
306 * systemd-analyze post-boot is broken for initrd
308 * systemd-analyze: data collection tools should be lightweight (few dependencies); data analysis tools can be heavyweight
310 * man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
312 * .device aliases need to be implemented with the "following" logic, probably.
314 * refuse taking lower-case variable names in sd_journal_send() and friends.
316 * load-fragment: when loading a unit file via a chain of symlinks
317 verify that it isn't masked via any of the names traversed.
319 * journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
324 * introduce Type=pid-file
326 * maybe allow services with ExecStop= set, but no ExecStart=?
328 * efi: implement /forcefsck as uefi variables thus not requiring file system altering to trigger a file system check
330 * efi: honor language efi variables for default language selection
332 * efi: honor timezone efi variables for default timezone selection
334 * efi: automatically mount EFI partition to /boot if no such entry exists in /etc/fstab and /boot is empty
335 gummiboot exports the EFI system partion (ESP) device:
336 /sys/firmware/efi/vars/LoaderDeviceIdentifier-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
337 Acpi(PNP0A03,0)/Pci(1F|2)/?/HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1)
338 '/' is the separator for the device path list
339 HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1) contains the GPT UUID of the ESP
341 * read the bootloader performance data (raw TSC) in systemd-analyze
342 /sys/firmware/efi/vars/LoaderTicksExec-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
344 /sys/firmware/efi/vars/LoaderTicksInit-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
346 /sys/firmware/efi/vars/LoaderTicksStartMenu-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
347 (only set if the menu was active)
349 * change Requires=basic.target to RequisiteOverride=basic.target
351 * support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
353 * nspawn: make use of device cgroup controller by default
355 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
357 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
359 * readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
361 * (attempt to) make Debianites happy:
362 - add syntax to reset ExecStart= lists (and similar)
364 * move passno parsing to fstab generator
366 * improve !/proc/*/loginuid situation: make /proc/*/loginuid less dependent on CONFIG_AUDIT,
367 or use the users cgroup information when /proc/*/loginuid is not available.
369 * pam_systemd: try to get old session id from cgroup, if audit sessionid cannot be determined
371 * pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
373 * maybe introduce ~/.config/locale.conf and apply it within PAM
375 * readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
377 * automount: implement expire
379 * services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)
381 * don't delete /tmp/systemd-namespace-* before a process is gone down
383 * vconsole: implement setterm -store -foreground xxx --background zzz

387 * fedora: make sshd and pam_loginuid work in nspawn containers
389 * fix utmp for console logins in containers
391 * Add pretty name for seats in logind
393 * ConditionSecurity= should learn about IMA and SMACK
397 * udev systemd unify:
398 - utf8 validator code
400 * udev: scsi_id -> sg3_utils -> kill scsi_id
402 * udev: add trigger --subsystem-match=usb/usb_device device
404 * allow configuration of console width/height in vconsole.conf
406 * cleanup syslog 'priority' vs. 'level' wording
408 * dbus upstream still refers to dbus.target and shouldn't
410 * when a service has the same env var set twice we actually store it twice and return that in systemctl show -p... We should only show the last setting
412 * support container_ttys=
414 * introduce mix of BindTo and Requisite
416 * journalctl: show multiline log messages sanely, expand tabs, and show all valid utf8 messages
418 * add DeleteSocketsOnStop=yes|no option to socket units
420 * journal: store euid in journal if it differs from uid
422 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
424 * journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
426 * add command to systemctl to plot dependency graph as tree (see rhbz 795365)
428 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
430 * default unix qlen is too small (10). bump sysctl? add sockopt?
432 * figure out whether we should leave dbus around during shutdown
434 * dbus: in fedora, make the machine a symlink to /etc/machine-id
436 * dbus: move dbus to early boot
438 * logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
440 * journal: deal nicely with byte-by-byte copied files, especially regards header
442 * journal: local deserializer of export mode, http server
444 * document the exit codes when services fail before they are exec()ed
446 * save coredump in Windows/Mozilla minidump format
448 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
450 * clean up session cgroups that remain after logout (think sshd), but eventually run empty
452 * support "systemctl stop foobar@.service" to stop all units matching a certain template
454 * logind: allow showing logout dialog from system
456 * document that %% can be used to write % in a string that is specifier extended
458 * when an instanced service exits, remove its parent cgroup too if possible.
460 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
462 * be able to specify a forced restart of service A where service B depends on, in case B
463 needs to be auto-respawned?
465 * Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
467 * when a bus name of a service disappears from the bus make sure to queue further activation requests
469 * something like ConditionExec= or ExecStartPre= without failure state
471 * tmpfiles: apply "x" on "D" too (see patch from William Douglas)
473 * don't set $HOME in services unless requested
475 * hide PAM/TCPWrap options in fragment parser when compile time disabled
477 * when we automatically restart a service, ensure we restart its rdeps, too.

489 in Avahi, RPC and other socket registration services.
491 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
493 * readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
495 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
497 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
499 * verify that the AF_UNIX sockets of a service in the fs still exist
500 when we start a service in order to avoid confusion when a user
501 assumes starting a service is enough to make it accessible
503 * Make it possible to set the keymap independently from the font on
504 the kernel cmdline. Right now setting one resets also the other.
506 * and a dbus call to generate target from current state
508 * drop /.readahead on bigger upgrades with yum
510 * add support for /bin/mount -s
512 * GC unreferenced jobs (such as .device jobs)
514 * write blog stories about:
515 - hwdb: what belongs into it, lsusb
516 - enabling dbus services
518 - how to make changes to sysctl and sysfs attributes
520 - how to pass throw-away units to systemd, or dynamically change properties of existing units
521 - how to integrate cgconfig and suchlike with systemd
522 - testing with Harald's awesome test kit
524 - how to develop against journal browsing APIs
525 - the journal HTTP iface
526 - non-cgroup resource management
527 - refreshed, longer missions statement
529 * allow port=0 in .socket units
531 * move readahead files into /var (look for them with .path units?)
533 * teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
535 * support systemd.mask= on the kernel command line.
537 * when key file cannot be found, read it from kbd in cryptsetup
539 * reuse mkdtemp namespace dirs in /tmp?
541 * recreate systemd's D-Bus private socket file on SIGUSR2
543 * Support --test based on current system state
545 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
547 * maybe introduce ExecRestartPre=
549 * configurable jitter for timer events
551 * timer events with system resume
553 * dot output for --test showing the 'initial transaction'
555 * writable cgroups dbus properties for live changes
557 * port over to LISTEN_FDS/LISTEN_PID:
558 - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
562 - libvirtd (/var/run/libvirt/libvirt-sock-ro)

581 - allow specification of socket mode/umask when allocating DBusServer
582 - allow disabling of fd passing when connecting a AF_UNIX connection
583 - allow disabling of UID passing for AUTH EXTERNAL
584 - always pass cred data along each message
586 * fix alsa mixer restore to not print error when no config is stored
588 * gnome-shell python script/glxinfo/is-accelerated must die
590 * make cryptsetup lower --iter-time
592 * patch kernel for xattr support in /dev, /proc/, /sys?
594 * NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
595 in an ~30 minutes window. It does not adjust larger differences. Find a way
596 to tell the kernel, to always do a full time sync when the RTC is in UTC and
597 we are in 11-minutes-mode. When we trust the system time to NTP we also want
600 * kernel: add device_type = "fb", "fbcon" to class "graphics"
604 * look for close() vs. close_nointr() vs. close_nointr_nofail()
606 * check for strerror(r) instead of strerror(-r)
608 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
610 * %m in printf() instead of strerror(errno);
614 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
616 * use secure_getenv() instead of getenv() where appropriate
618 * link up selected blog stories from man pages and unit files Documentation= fields
620 Scheduled for removal or fixing:
622 * xxxOverridable dependencies (probably: fix)
