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 * add configure switch for enabling/disabling efi stuff
25 * introduce ExecCondition= in services
27 * unify killing logic of service, socket, mount, swap units
29 * logind: document new PrepareForSleep(false) semantics and UnlockSessions call in wiki
31 * if we have systemd-analyze in C "systemctl dot" should move there too
33 * fsck hookup for the ESP mount is missing
35 * external: maybe it is time to patch procps so that "ps" links to
36 libsystemd-logind to print a pretty service name, seat name, session
37 name in its output. Currently it only shows cgroup membership, but
38 that's sometimes kinda hard to parse for a human.
40 * write man page for efi boot generator
42 * maybe not install getty@tty1.service symlink in /etc but in /usr?
44 * re-enable "make check" for gtk-doc (broken for unknown reason)
46 * "systemctl disable" on a static unit prints no message and does
47 nothing. "systemctl enable" does nothing, and gives a bad message
48 about it. Should fix both to print nice actionable messages.
50 * fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
51 https://bugzilla.redhat.com/show_bug.cgi?id=812826
54 - don't filter out duplicate settings
55 - support high-level cgroup setting syntax in systemctl. Example: "systemctl set-cgroup-attr MemoryLimit 5K"
56 - support writte string mapping even for non-high-level settings
57 - add man page for systemctl commands
58 - make sure we work fine with multi-line strings
60 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
62 * kernel cmdline switch to turn off predictable network interface names
64 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
66 * logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
68 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
70 * DeviceAllow/DeviceDeny: disallow everything by default, but whitelist /dev/zero, /dev/null and friends
72 * service: watchdog logic: for testing purposes allow ping, but do not require pong
74 * journald: when dropping msgs due to ratelimit make sure to write
75 "dropped %u messages" not only when we are about to print the next
76 message that works, but alraedy after a short tiemout
78 * journald: also get thread ID from client, plus thread name
80 * check if we can make journalctl by default use --follow mode inside of less if called without args?
82 * Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
84 * journal is not closed properly at shutdown when run in a container?
86 * journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
88 * When shutdown.target is queued begin with an asynchronous sync()?
90 * add API to close/reopen/get fd for journal client fd in libsystemd-journal.
92 * maybe add API to send pairs of iovecs via sd_journal_send
94 * fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
96 * declare the local journal protocol stable in the wiki interface chart
98 * journal: reuse XZ context
100 * sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
102 * introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
104 * timer units should get the ability to trigger when:
105 - CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
108 * update the kernel's TZ (sys_tz) when DST changes
110 * sync down the system time to the RTC when:
111 - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
112 - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
113 This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
114 mode, it will never touch the RTC if the no reliable time source is active or the
115 user did not request anything like it.
117 * When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
120 - implement conditional properties (dmi matches)
121 - hwdb --filter=ID_DRIVE_*
123 * if booted in "quiet" mode, and an error happens, turn on status
124 output again, so that the emergency mode isn't totally
125 surprising. Also, terminate plymouth.
127 * localectl: add listing support for X11 keymaps, by parsing /usr/share/X11/xkb/rules/xorg.lst
129 * libunwind support for coredump pattern hook, and includes this in
130 the message for coredumps. After all, libunwind is now capable to
131 unwind coredumps since a few weeks ago. This probably requires that
132 we have nice support for multi-line messages on display in
133 logs-show.c. Alternatively: use libelfutil, which seems to be the
134 better supported alternative.
136 * figure out relation of --all and --full in the various tools
138 * journal: when writing journal auto-rotate if time jumps backwards
140 * introduce new "journal" group in place of adm? introduce groups for the various mini daemons?
142 * journal: add a setgid "adm" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
144 * journactl: support negative filtering, i.e. FOOBAR!="waldo",
145 and !FOOBAR for events without FOOBAR.
147 * print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
149 * add libsystemd-password or so to query passwords during boot using the password agent logic
151 * journal: when rotating, copy over old acls/access mode
153 * journal: document why we do not give ownership to journal files to the user that created them but use FS ACLs for that
155 * journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
157 * 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
159 * 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.
161 * 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().
163 * fedup: add --unit to systemctl switch-root somehow
164 * fedup: don't delete initrd on switch-root
167 * journal: find a way to allow dropping history early, based on priority, other rules
169 * journal: When used on NFS, check payload hashes
171 * journal: When used on NFS make sure wake up sd_journal_wait() every 2s, to handle missing inotify
173 * document that people can use file system ACLs to manage access to journal files, with example
175 * timedated: export boolean that clarifies whether NTP is even available
177 * timedated: refuse time changes when NTP is on
179 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
181 * document unit_name_mangle()
183 * add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
185 * introduce generic AUGMENT_PID=, AUGMENT_DEVICE= fields
187 * deal with sendmail/postfix exclusivity
189 * systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
191 * systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
193 * on shutdown: move utmp, wall, audit logic all into PID 1 itself, get rid of systemd-update-utmp-runlevel
195 * add "provisioning" instructions to setup an empty /etc + /var
196 - used to setup a new container from a shared /usr
197 - superset of tmpfiles model
198 - instructions shipped by packages and stored in /usr/lib/
199 - compose /etc/passwd and /etc/group, copy files
200 - able to create uid + gid used by packages, for file ownership
202 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
203 waiting for the timeout
205 * high level net_prio setting in execution context
207 * Introduce journalctl -b <nr> to show journal messages of a previous boot
209 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
211 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
213 * WorkingDirectory: support env var replacements like in ExecStart= so that people can use $HOME
215 * refuse boot if /etc/machine-id is not useful (or set taint?)
217 * nspawn: consider changing users for -u with su, so that NSS resolving works correctly
219 * nspawn: implement personality changes a la linux32(8)
221 * cryptsetup-generator: warn if the password files are world-readable
223 * cryptsetup-generator: add RequiresMountsFor= to cryptseup service files referencing a file, similar for devices
225 * cryptsetup-generator: allow specification of passwords in crypttab itself
227 * document that deps in [Unit] sections ignore Alias= fileds in
228 [Install] units of other units, unless those units are disabled
230 * instantiated [Install] for target units
231 https://bugs.freedesktop.org/show_bug.cgi?id=54377
233 * move debug shell to tty6 and make sure this doesn't break the gettys on tty6
235 * move cryptsetup key caching into kernel keyctl?
236 https://bugs.freedesktop.org/show_bug.cgi?id=54982
238 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
239 https://bugs.freedesktop.org/show_bug.cgi?id=54712
241 * after deserializing sockets in socket.c we should reapply sockopts and things
243 * make timer units go away after they elapsed
245 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
246 (network and remote-fs on shutdown)
248 * come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
250 * journald: add kernel cmdline option to disable ratelimiting for debug purposes
252 * move PID 1 segfaults to /var/lib/systemd/coredump?
254 * Document word splitting syntax for ExecStart= and friends
256 * create /sbin/init symlinks from the build system
258 * Query Paul Moore about relabelling socket fds while they are open
260 * journald: check whether it is OK if the client can still modify delivered journal entries
262 * journal live copy, based on libneon (client) and libmicrohttpd
264 * system-wide seccomp filter
266 * system.conf should have controls for cgroups
268 * bind mount read-only the cgroup tree higher than nspawn
270 * allow writing multiple conditions in unit files on one line
272 * explore multiple service instances per listening socket idea
274 * 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.
276 * shutdown: don't read-only mount anything when running in container
278 * nspawn: --read-only is not applied recursively to submounts
280 * MountFlags=shared acts as MountFlags=slave right now.
282 * ReadOnlyDirectories= is not applied recursively to submounts
284 * drop PID 1 reloading, only do reexecing (difficult: Reload()
285 currently is properly synchronous, Reexec() is weird, because we
286 can't delay the response properly until we are back, so instead of
287 being properly synchronous we just keep open the fd and close it
288 when done. That means clients don't get a successful method reply,
289 but much rather a disconnect on success.
291 * document that service reload may be implemented as service reexec
293 * remember which condition failed for services, not just the fact that something failed
295 * use opterr = 0 for all getopt tools
297 * properly handle loop back mounts via fstab, especially regards to fsck/passno
299 * allow services with no ExecStart= but with an ExecStop=
301 * add proper journal support to "systemctl --user status ..."
303 * add _SYSTEMD_USER_UNIT= field to journal entries
305 * dracut-shutdown needs to be ordered before unmounting /boot
307 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
309 * rename "userspace" to "core-os"
311 * systemctl: "Journal has been rotated since unit was started." message is misleading
313 * syscall filter: add knowledge about compat syscalls
315 * syscall filter: don't enforce no new privs?
317 * syscall filter: option to return EPERM rather than SIGSYS?
319 * syscall filter: port to libseccomp
321 * logind: wakelock/opportunistic suspend support
323 * systemd-analyze post-boot is broken for initrd
325 * systemd-analyze: data collection tools should be lightweight (few dependencies); data analysis tools can be heavyweight
327 * man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
329 * .device aliases need to be implemented with the "following" logic, probably.
331 * refuse taking lower-case variable names in sd_journal_send() and friends.
333 * load-fragment: when loading a unit file via a chain of symlinks
334 verify that it isn't masked via any of the names traversed.
336 * journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
338 * introduce Type=pid-file
340 * maybe allow services with ExecStop= set, but no ExecStart=?
343 - honor language efi variables for default language selection (if there are any?)
344 - honor timezone efi variables for default timezone selection (if there are any?)
345 - introduce bootctl (backed by systemd-bootd) to control temporary and persistent default boot goal plus efi variables
347 * change Requires=basic.target to RequisiteOverride=basic.target
349 * support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
351 * nspawn: make use of device cgroup controller by default
353 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
355 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
357 * readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
359 * move passno parsing to fstab generator
361 * improve !/proc/*/loginuid situation: make /proc/*/loginuid less dependent on CONFIG_AUDIT,
362 or use the users cgroup information when /proc/*/loginuid is not available.
364 * pam_systemd: try to get old session id from cgroup, if audit sessionid cannot be determined
366 * pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
368 * readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
370 * automount: implement expire:
371 - set superblock timeout AUTOFS_DEV_IOCTL_TIMEOUT_CMD
372 - periodically run AUTOFS_DEV_IOCTL_EXPIRE_CMD
373 - every timeout/4 (original autofs logic)
374 - blocking, needs a thread
376 - receive expire packet on pipe if kernel tells the timeout is over
378 - answer expire packet on pipe with AUTOFS_DEV_IOCTL_{READY,FAIL}_CMD
379 - AUTOFS_DEV_IOCTL_EXPIRE_CMD returns
381 * services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)
383 * don't delete /tmp/systemd-namespace-* before a process is gone down
385 * ExecOnFailure=/usr/bin/foo
387 * fix utmp for console logins in containers
389 * Add pretty name for seats in logind
391 * ConditionSecurity= should learn about IMA and SMACK
394 - remove all (misguided from day 1) userspace firmware_class handling
396 - unify utf8 validator code with shared/
398 - add trigger --subsystem-match=usb/usb_device device
400 * cleanup syslog 'priority' vs. 'level' wording
402 * dbus upstream still refers to dbus.target and shouldn't
404 * 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
406 * support container_ttys=
408 * introduce mix of BindTo and Requisite
410 * journalctl: show multiline log messages sanely, expand tabs, and show all valid utf8 messages
412 * add DeleteSocketsOnStop=yes|no option to socket units
414 * journal: store euid in journal if it differs from uid
416 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
418 * journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
420 * add command to systemctl to plot dependency graph as tree (see rhbz 795365)
422 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
424 * default unix qlen is too small (10). bump sysctl? add sockopt?
426 * figure out whether we should leave dbus around during shutdown
428 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
430 * dbus: move dbus to early boot
432 * logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
434 * journal: deal nicely with byte-by-byte copied files, especially regards header
436 * journal: local deserializer of export mode, http server
438 * document the exit codes when services fail before they are exec()ed
440 * save coredump in Windows/Mozilla minidump format
442 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
444 * clean up session cgroups that remain after logout (think sshd), but eventually run empty
446 * support "systemctl stop foobar@.service" to stop all units matching a certain template
448 * logind: allow showing logout dialog from system
450 * document that %% can be used to write % in a string that is specifier extended
452 * when an instanced service exits, remove its parent cgroup too if possible.
454 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
456 * be able to specify a forced restart of service A where service B depends on, in case B
457 needs to be auto-respawned?
459 * Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
461 * when a bus name of a service disappears from the bus make sure to queue further activation requests
463 * something like ConditionExec= or ExecCondition= without failure state
465 * tmpfiles: apply "x" on "D" too (see patch from William Douglas)
467 * don't set $HOME in services unless requested
469 * hide PAM/TCPWrap options in fragment parser when compile time disabled
471 * when we automatically restart a service, ensure we restart its rdeps, too.
473 * allow Type=simple with PIDFile=
474 https://bugzilla.redhat.com/show_bug.cgi?id=723942
476 * move PAM code into its own binary
478 * logind: spawn user@..service on login
480 * logind: non-local X11 server handling
482 * implement Register= switch in .socket units to enable registration
483 in Avahi, RPC and other socket registration services.
485 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
487 * readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
489 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
491 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
493 * verify that the AF_UNIX sockets of a service in the fs still exist
494 when we start a service in order to avoid confusion when a user
495 assumes starting a service is enough to make it accessible
497 * Make it possible to set the keymap independently from the font on
498 the kernel cmdline. Right now setting one resets also the other.
500 * and a dbus call to generate target from current state
502 * drop /.readahead on bigger upgrades with yum
504 * add support for /bin/mount -s
506 * GC unreferenced jobs (such as .device jobs)
508 * write blog stories about:
509 - hwdb: what belongs into it, lsusb
510 - enabling dbus services
512 - how to make changes to sysctl and sysfs attributes
514 - how to pass throw-away units to systemd, or dynamically change properties of existing units
515 - how to integrate cgconfig and suchlike with systemd
516 - testing with Harald's awesome test kit
518 - how to develop against journal browsing APIs
519 - the journal HTTP iface
520 - non-cgroup resource management
521 - dynamic resource management with cgroups
522 - refreshed, longer missions statement
523 - celendar time events
525 * allow port=0 in .socket units
527 * move readahead files into /var (look for them with .path units?)
529 * teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
531 * support systemd.mask= on the kernel command line.
533 * when key file cannot be found, read it from kbd in cryptsetup
535 * reuse mkdtemp namespace dirs in /tmp?
537 * recreate systemd's D-Bus private socket file on SIGUSR2
539 * Support --test based on current system state
541 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
543 * maybe introduce ExecRestartPre=
545 * configurable jitter for timer events
547 * timer events with system resume
549 * dot output for --test showing the 'initial transaction'
551 * writable cgroups dbus properties for live changes
553 * port over to LISTEN_FDS/LISTEN_PID:
554 - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
558 - libvirtd (/var/run/libvirt/libvirt-sock-ro)
559 - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
562 * fingerprint.target, wireless.target, gps.target, netdevice.target
564 * io priority during initialization
566 * systemctl list-jobs - show dependencies
568 * add systemctl switch to dump transaction without executing it
570 * drop cap bounding set in readahead and other services
576 - natively watch for dbus-*.service symlinks (PENDING)
577 - allow specification of socket mode/umask when allocating DBusServer
578 - allow disabling of fd passing when connecting a AF_UNIX connection
579 - allow disabling of UID passing for AUTH EXTERNAL
580 - always pass cred data along each message
582 * fix alsa mixer restore to not print error when no config is stored
584 * gnome-shell python script/glxinfo/is-accelerated must die
586 * make cryptsetup lower --iter-time
588 * patch kernel for xattr support in /dev, /proc/, /sys?
590 * NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
591 in an ~30 minutes window. It does not adjust larger differences. Find a way
592 to tell the kernel, to always do a full time sync when the RTC is in UTC and
593 we are in 11-minutes-mode. When we trust the system time to NTP we also want
596 * kernel: add device_type = "fb", "fbcon" to class "graphics"
600 * look for close() vs. close_nointr() vs. close_nointr_nofail()
602 * check for strerror(r) instead of strerror(-r)
604 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
606 * %m in printf() instead of strerror(errno);
610 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
612 * use secure_getenv() instead of getenv() where appropriate
614 * link up selected blog stories from man pages and unit files Documentation= fields
616 Scheduled for removal or fixing:
618 * xxxOverridable dependencies (probably: fix)
