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.
19 * create /var/log/journal/
23 * write man page for efi boot generator
25 * document bootloader interface in wiki
27 * link runlevel targets on install only if sysv compat is enabled
29 * logind: when executing sleep/shutdown job, keep track of its id, and
30 as long as the job is running refuse any further operation.
32 * maybe not install getty@tty1.service symlink in /etc but in /usr?
34 * re-enable "make check" for gtk-doc (broken for unknown reason)
36 * logind: make PrepareForSuspend(false) an official api for notification of resumes
38 * "systemctl disable" on a static unit prints no message and does
39 nothing. "systemctl enable" does nothing, and gives a bad message
40 about it. Should fix both to print nice actionable messages.
42 * fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
43 https://bugzilla.redhat.com/show_bug.cgi?id=812826
45 * add "loginctl unlock-sessions" as counterpart for "loginctl lock-sessions"
48 - don't filter out duplicate settings
49 - support high-level cgroup setting syntax in systemctl. Example: "systemctl set-cgroup-attr MemoryLimit 5K"
50 - support writte string mapping even for non-high-level settings
51 - add man page for systemctl commands
52 - make sure we work fine with multi-line strings
54 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
56 * kernel cmdline switch to turn off predictable network interface names
58 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
60 * logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
62 * service: when killing a service with SIGKILL always kill all processes, even if for SIGTERM we only killed the main process
64 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
66 * DeviceAllow/DeviceDeny: disallow everything by default, but whitelist /dev/zero, /dev/null and friends
68 * service: watchdog logic: for testing purposes allow ping, but do not require pong
70 * journald: when dropping msgs due to ratelimit make sure to write
71 "dropped %u messages" not only when we are about to print the next
72 message that works, but alraedy after a short tiemout
74 * journald: also get thread ID from client, plus thread name
76 * check if we can make journalctl by default use --follow mode inside of less if called without args?
78 * Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
80 * journal is not closed properly at shutdown when run in a container?
82 * journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
84 * When shutdown.target is queued begin with an asynchronous sync()?
86 * add API to close/reopen/get fd for journal client fd in libsystemd-journal.
88 * maybe add API to send pairs of iovecs via sd_journal_send
90 * fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
92 * declare the local journal protocol stable in the wiki interface chart
94 * journal: reuse XZ context
96 * sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
98 * introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
100 * timer units should get the ability to trigger when:
101 - CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
104 * update the kernel's TZ (sys_tz) when DST changes
106 * sync down the system time to the RTC when:
107 - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
108 - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
109 This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
110 mode, it will never touch the RTC if the no reliable time source is active or the
111 user did not request anything like it.
113 * When we begin with system shutdown all kind of suspend/hibernation should be prohibited until shutdown/reboot
115 * When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
118 - implement conditional properties (dmi matches)
119 - hwdb --filter=ID_DRIVE_*
121 * if booted in "quiet" mode, and an error happens, turn on status
122 output again, so that the emergency mode isn't totally
123 surprising. Also, terminate plymouth.
125 * localectl: add listing support for X11 keymaps, by parsing /usr/share/X11/xkb/rules/xorg.lst
127 * libunwind support for coredump pattern hook, and includes this in
128 the message for coredumps. After all, libunwind is now capable to
129 unwind coredumps since a few weeks ago. This probably requires that
130 we have nice support for multi-line messages on display in
131 logs-show.c. Alternatively: use libelfutil, which seems to be the
132 better supported alternative.
134 * figure out relation of --all and --full in the various tools
136 * journal: when writing journal auto-rotate if time jumps backwards
138 * introduce new "journal" group in place of adm? introduce groups for the various mini daemons?
140 * journal: add a setgid "adm" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
142 * journactl: support negative filtering, i.e. FOOBAR!="waldo",
143 and !FOOBAR for events without FOOBAR.
145 * print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
147 * add libsystemd-password or so to query passwords during boot using the password agent logic
149 * journal: when rotating, copy over old acls/access mode
151 * journal: document why we do not give ownership to journal files to the user that created them but use FS ACLs for that
153 * journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
155 * 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
157 * 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.
159 * 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().
161 * fedup: add --unit to systemctl switch-root somehow
162 * fedup: don't delete initrd on switch-root
165 * journal: find a way to allow dropping history early, based on priority, other rules
167 * journal: When used on NFS, check payload hashes
169 * journal: When used on NFS make sure wake up sd_journal_wait() every 2s, to handle missing inotify
171 * document that people can use file system ACLs to manage access to journal files, with example
173 * timedated: export boolean that clarifies whether NTP is even available
175 * timedated: refuse time changes when NTP is on
177 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
179 * document unit_name_mangle()
181 * add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
183 * introduce generic AUGMENT_PID=, AUGMENT_DEVICE= fields
185 * deal with sendmail/postfix exclusivity
187 * systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
189 * systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
191 * on shutdown: move utmp, wall, audit logic all into PID 1 itself, get rid of systemd-update-utmp-runlevel
193 * add "provisioning" instructions to setup an empty /etc + /var
194 - used to setup a new container from a shared /usr
195 - superset of tmpfiles model
196 - instructions shipped by packages and stored in /usr/lib/
197 - compose /etc/passwd and /etc/group, copy files
198 - able to create uid + gid used by packages, for file ownership
200 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
201 waiting for the timeout
203 * high level net_prio setting in execution context
205 * Introduce journalctl -b <nr> to show journal messages of a previous boot
207 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
209 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
211 * WorkingDirectory: support env var replacements like in ExecStart= so that people can use $HOME
213 * refuse boot if /etc/machine-id is not useful (or set taint?)
215 * nspawn: consider changing users for -u with su, so that NSS resolving works correctly
217 * nspawn: implement personality changes a la linux32(8)
219 * cryptsetup-generator: warn if the password files are world-readable
221 * cryptsetup-generator: add RequiresMountsFor= to cryptseup service files referencing a file, similar for devices
223 * cryptsetup-generator: allow specification of passwords in crypttab itself
225 * document that deps in [Unit] sections ignore Alias= fileds in
226 [Install] units of other units, unless those units are disabled
228 * instantiated [Install] for target units
229 https://bugs.freedesktop.org/show_bug.cgi?id=54377
231 * move debug shell to tty6 and make sure this doesn't break the gettys on tty6
233 * move cryptsetup key caching into kernel keyctl?
234 https://bugs.freedesktop.org/show_bug.cgi?id=54982
236 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
237 https://bugs.freedesktop.org/show_bug.cgi?id=54712
239 * after deserializing sockets in socket.c we should reapply sockopts and things
241 * make timer units go away after they elapsed
243 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
244 (network and remote-fs on shutdown)
246 * come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
248 * journald: add kernel cmdline option to disable ratelimiting for debug purposes
250 * move PID 1 segfaults to /var/lib/systemd/coredump?
252 * Document word splitting syntax for ExecStart= and friends
254 * create /sbin/init symlinks from the build system
256 * Query Paul Moore about relabelling socket fds while they are open
258 * journald: check whether it is OK if the client can still modify delivered journal entries
260 * journal live copy, based on libneon (client) and libmicrohttpd
262 * system-wide seccomp filter
264 * system.conf should have controls for cgroups
266 * bind mount read-only the cgroup tree higher than nspawn
268 * allow writing multiple conditions in unit files on one line
270 * explore multiple service instances per listening socket idea
272 * 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.
274 * shutdown: don't read-only mount anything when running in container
276 * nspawn: --read-only is not applied recursively to submounts
278 * MountFlags=shared acts as MountFlags=slave right now.
280 * ReadOnlyDirectories= is not applied recursively to submounts
282 * drop PID 1 reloading, only do reexecing (difficult: Reload()
283 currently is properly synchronous, Reexec() is weird, because we
284 can't delay the response properly until we are back, so instead of
285 being properly synchronous we just keep open the fd and close it
286 when done. That means clients don't get a successful method reply,
287 but much rather a disconnect on success.
289 * document that service reload may be implemented as service reexec
291 * remember which condition failed for services, not just the fact that something failed
293 * use opterr = 0 for all getopt tools
295 * properly handle loop back mounts via fstab, especially regards to fsck/passno
297 * allow services with no ExecStart= but with an ExecStop=
299 * add proper journal support to "systemctl --user status ..."
301 * add _SYSTEMD_USER_UNIT= field to journal entries
303 * dracut-shutdown needs to be ordered before unmounting /boot
305 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
307 * rename "userspace" to "core-os"
309 * systemctl: "Journal has been rotated since unit was started." message is misleading
311 * syscall filter: add knowledge about compat syscalls
313 * syscall filter: don't enforce no new privs?
315 * syscall filter: option to return EPERM rather than SIGSYS?
317 * syscall filter: port to libseccomp
319 * logind: wakelock/opportunistic suspend support
321 * systemd-analyze post-boot is broken for initrd
323 * systemd-analyze: data collection tools should be lightweight (few dependencies); data analysis tools can be heavyweight
325 * man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
327 * .device aliases need to be implemented with the "following" logic, probably.
329 * refuse taking lower-case variable names in sd_journal_send() and friends.
331 * load-fragment: when loading a unit file via a chain of symlinks
332 verify that it isn't masked via any of the names traversed.
334 * journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
336 * introduce Type=pid-file
338 * maybe allow services with ExecStop= set, but no ExecStart=?
341 - implement /forcefsck as efi variables thus not requiring file system altering to trigger a file system check
342 - honor language efi variables for default language selection
343 - honor timezone efi variables for default timezone selection
344 - automatically (auto)mount EFI partition to /boot if no such entry exists in /etc/fstab and /boot is empty
345 gummiboot exports the EFI system partion's GPT PARTUUID:
346 $ cat /sys/firmware/efi/efivars/LoaderDevicePartUUID-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f
347 1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1
348 - introduce bootctl (backed by systemd-bootd) to control temporary and persistent default boot goal plus efi variables
350 * change Requires=basic.target to RequisiteOverride=basic.target
352 * support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
354 * nspawn: make use of device cgroup controller by default
356 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
358 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
360 * readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
362 * move passno parsing to fstab generator
364 * improve !/proc/*/loginuid situation: make /proc/*/loginuid less dependent on CONFIG_AUDIT,
365 or use the users cgroup information when /proc/*/loginuid is not available.
367 * pam_systemd: try to get old session id from cgroup, if audit sessionid cannot be determined
369 * pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
371 * maybe introduce ~/.config/locale.conf and apply it within PAM
373 * readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
375 * automount: implement expire:
376 - set superblock timeout AUTOFS_DEV_IOCTL_TIMEOUT_CMD
377 - periodically run AUTOFS_DEV_IOCTL_EXPIRE_CMD
378 - every timeout/4 (original autofs logic)
379 - blocking, needs a thread
381 - receive expire packet on pipe if kernel tells the timeout is over
383 - answer expire packet on pipe with AUTOFS_DEV_IOCTL_{READY,FAIL}_CMD
384 - AUTOFS_DEV_IOCTL_EXPIRE_CMD returns
386 * services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)
388 * don't delete /tmp/systemd-namespace-* before a process is gone down
390 * ExecOnFailure=/usr/bin/foo
392 * fedora: make sshd and pam_loginuid work in nspawn containers
394 * fix utmp for console logins in containers
396 * Add pretty name for seats in logind
398 * ConditionSecurity= should learn about IMA and SMACK
401 - remove all (misguided from day 1) userspace firmware_class handling
403 - unify utf8 validator code with shared/
405 - add trigger --subsystem-match=usb/usb_device device
407 * cleanup syslog 'priority' vs. 'level' wording
409 * dbus upstream still refers to dbus.target and shouldn't
411 * 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
413 * support container_ttys=
415 * introduce mix of BindTo and Requisite
417 * journalctl: show multiline log messages sanely, expand tabs, and show all valid utf8 messages
419 * add DeleteSocketsOnStop=yes|no option to socket units
421 * journal: store euid in journal if it differs from uid
423 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
425 * journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
427 * add command to systemctl to plot dependency graph as tree (see rhbz 795365)
429 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
431 * default unix qlen is too small (10). bump sysctl? add sockopt?
433 * figure out whether we should leave dbus around during shutdown
435 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
437 * dbus: move dbus to early boot
439 * logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
441 * journal: deal nicely with byte-by-byte copied files, especially regards header
443 * journal: local deserializer of export mode, http server
445 * document the exit codes when services fail before they are exec()ed
447 * save coredump in Windows/Mozilla minidump format
449 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
451 * clean up session cgroups that remain after logout (think sshd), but eventually run empty
453 * support "systemctl stop foobar@.service" to stop all units matching a certain template
455 * logind: allow showing logout dialog from system
457 * document that %% can be used to write % in a string that is specifier extended
459 * when an instanced service exits, remove its parent cgroup too if possible.
461 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
463 * be able to specify a forced restart of service A where service B depends on, in case B
464 needs to be auto-respawned?
466 * Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
468 * when a bus name of a service disappears from the bus make sure to queue further activation requests
470 * something like ConditionExec= or ExecCondition= without failure state
472 * tmpfiles: apply "x" on "D" too (see patch from William Douglas)
474 * don't set $HOME in services unless requested
476 * hide PAM/TCPWrap options in fragment parser when compile time disabled
478 * when we automatically restart a service, ensure we restart its rdeps, too.
480 * allow Type=simple with PIDFile=
481 https://bugzilla.redhat.com/show_bug.cgi?id=723942
483 * move PAM code into its own binary
485 * logind: spawn user@..service on login
487 * logind: non-local X11 server handling
489 * implement Register= switch in .socket units to enable registration
490 in Avahi, RPC and other socket registration services.
492 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
494 * readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
496 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
498 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
500 * verify that the AF_UNIX sockets of a service in the fs still exist
501 when we start a service in order to avoid confusion when a user
502 assumes starting a service is enough to make it accessible
504 * Make it possible to set the keymap independently from the font on
505 the kernel cmdline. Right now setting one resets also the other.
507 * and a dbus call to generate target from current state
509 * drop /.readahead on bigger upgrades with yum
511 * add support for /bin/mount -s
513 * GC unreferenced jobs (such as .device jobs)
515 * write blog stories about:
516 - hwdb: what belongs into it, lsusb
517 - enabling dbus services
519 - how to make changes to sysctl and sysfs attributes
521 - how to pass throw-away units to systemd, or dynamically change properties of existing units
522 - how to integrate cgconfig and suchlike with systemd
523 - testing with Harald's awesome test kit
525 - how to develop against journal browsing APIs
526 - the journal HTTP iface
527 - non-cgroup resource management
528 - dynamic resource management with cgroups
529 - refreshed, longer missions statement
530 - celendar time events
532 * allow port=0 in .socket units
534 * move readahead files into /var (look for them with .path units?)
536 * teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
538 * support systemd.mask= on the kernel command line.
540 * when key file cannot be found, read it from kbd in cryptsetup
542 * reuse mkdtemp namespace dirs in /tmp?
544 * recreate systemd's D-Bus private socket file on SIGUSR2
546 * Support --test based on current system state
548 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
550 * maybe introduce ExecRestartPre=
552 * configurable jitter for timer events
554 * timer events with system resume
556 * dot output for --test showing the 'initial transaction'
558 * writable cgroups dbus properties for live changes
560 * port over to LISTEN_FDS/LISTEN_PID:
561 - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
565 - libvirtd (/var/run/libvirt/libvirt-sock-ro)
566 - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
569 * fingerprint.target, wireless.target, gps.target, netdevice.target
571 * io priority during initialization
573 * systemctl list-jobs - show dependencies
575 * add systemctl switch to dump transaction without executing it
577 * drop cap bounding set in readahead and other services
583 - natively watch for dbus-*.service symlinks (PENDING)
584 - allow specification of socket mode/umask when allocating DBusServer
585 - allow disabling of fd passing when connecting a AF_UNIX connection
586 - allow disabling of UID passing for AUTH EXTERNAL
587 - always pass cred data along each message
589 * fix alsa mixer restore to not print error when no config is stored
591 * gnome-shell python script/glxinfo/is-accelerated must die
593 * make cryptsetup lower --iter-time
595 * patch kernel for xattr support in /dev, /proc/, /sys?
597 * NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
598 in an ~30 minutes window. It does not adjust larger differences. Find a way
599 to tell the kernel, to always do a full time sync when the RTC is in UTC and
600 we are in 11-minutes-mode. When we trust the system time to NTP we also want
603 * kernel: add device_type = "fb", "fbcon" to class "graphics"
607 * look for close() vs. close_nointr() vs. close_nointr_nofail()
609 * check for strerror(r) instead of strerror(-r)
611 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
613 * %m in printf() instead of strerror(errno);
617 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
619 * use secure_getenv() instead of getenv() where appropriate
621 * link up selected blog stories from man pages and unit files Documentation= fields
623 Scheduled for removal or fixing:
625 * xxxOverridable dependencies (probably: fix)
