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 * service: when killing a service with SIGKILL always kill all processes
24 * rewrite #!/usr/bin/python line in python scripts to use @PYTHON@ instead
26 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
28 * udev: only reset mode/gid of /dev/tty1 and friends on ACTION=add, not ACTION=changed
30 * DeviceAllow/DeviceDeny: disallow everything by default, but whitelist /dev/zero, /dev/null and friends
32 * service: watchdog logic: for testing purposes allow ping, but do not require pong
34 * kill insserv code, people should really use a generator for this
36 * journald: when dropping msgs due to ratelimit make sure to write
37 "dropped %u messages" not only when we are about to print the next
38 message that works, but alraedy after a short tiemout
40 * add form factor to /etc/machine-info
42 * use C11 static_assert() where we currently use assert_cc()
44 * journald: also get thread ID from client, plus thread name
46 * check if we can make journalctl by default use --follow mode inside of less if called without args?
48 * Addd a verbose mode to "systemctl start" and friends that explains what is being done or not done
50 * "systemctl is-failed" to join "systemctl is-active" and "systemctl is-enabled".
52 * journal is not closed properly at shutdown when run in a container?
54 * All log messages generated from socket.c, service.c, ... should
55 include _SYSTEMD_UNIT= fields so that "systemctl status" can show
56 them along with the unit
58 * use polkit "imply" for binding hostname actions together
60 * journal: when waiting for journal additions always sleep at least 1s or so, in order to minimize wakeups
62 * When shutdown.target is queued begin with an asynchronous sync()?
64 * Add ConditionBatteryPower= or ConditionACPower=? (but definitely not both)
66 * add API to close/reopen/get fd for journal client fd in libsystemd-journal.
68 * maybe add API to send pairs of iovecs via sd_journal_send
70 * fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
72 * declare the local journal protocol stable in the wiki interface chart
74 * journal: reuse XZ context
76 * sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
78 * introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
80 * timer units should get the ability to trigger when:
81 - CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
84 * update the kernel's TZ (sys_tz) when DST changes
86 * sync down the system time to the RTC when:
87 - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
88 - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
89 This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
90 mode, it will never touch the RTC if the no reliable time source is active or the
91 user did not request anything like it.
93 * When we begin with system shutdown all kind of suspend/hibernation should be prohibited until shutdown/reboot
95 * When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
98 - implement conditional properties (dmi matches)
99 - hwdb --filter=ID_DRIVE_*
100 - find out what to do for blockdevs and skipping scsi modaliases
101 - move writing code to src/libudev/libudev-hwdb-private.c
103 * if booted in "quiet" mode, and an error happens, turn on status output again, so that the emergency mode isn't totally surprising
105 * localectl: add listing support for X11 keymaps, by parsing /usr/share/X11/xkb/rules/xorg.lst
107 * libunwind support for coredump pattern hook, and includes this in
108 the message for coredumps. After all, libunwind is now capable to
109 unwind coredumps since a few weeks ago. This probably requires that
110 we have nice support for multi-line messages on display in logs-show.c.
112 * figure out relation of --all and --full in the various tools
114 * journal: when writing journal auto-rotate if time jumps backwards
116 * introduce new "journal" group in place of adm? introduce groups for the various mini daemons?
118 * journal: add a setgid "adm" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
120 * link up selected blog stories from man pages and unit files Documentation= fields?
122 * journactl: support negative filtering, i.e. FOOBAR!="waldo",
123 and !FOOBAR for events without FOOBAR.
125 * print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
127 * add libsystemd-password or so to query passwords during boot using the password agent logic
129 * journal: when rotating, copy over old acls/access mode
131 * journal: document why we do not give ownership to journal files to the user that created them but use FS ACLs for that
133 * journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
135 * 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
137 * 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.
139 * 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().
141 * fedup: add --unit to systemctl switch-root somehow
142 * fedup: don't delete initrd on switch-root
145 * journal: find a way to allow dropping history early, based on priority, other rules
147 * journal: When used on NFS, check payload hashes
149 * journal: When used on NFS make sure wake up sd_journal_wait() every 2s, to handle missing inotify
151 * document that people can use file system ACLs to manage access to journal files, with example
153 * don't show cgroup in "systemctl status" if empty/non-existent, especially for foreign .mount units
155 * timedated: export boolean that clarifies whether NTP is even available
157 * timedated: refuse time changes when NTP is on
159 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
161 * document unit_name_mangle()
163 * add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
165 * introduce generic AUGMENT_PID=, AUGMENT_DEVICE= fields
167 * deal with sendmail/postfix exclusivity
169 * systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
171 * systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
173 * on shutdown: move utmp, wall, audit logic all into PID 1 itself, get rid of systemd-update-utmp-runlevel
175 * add "provisioning" instructions to setup an empty /etc + /var
176 - used to setup a new container from a shared /usr
177 - superset of tmpfiles model
178 - instructions shipped by packages and stored in /usr/lib/
179 - compose /etc/passwd and /etc/group, copy files
180 - able to create uid + gid used by packages, for file ownership
182 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
183 waiting for the timeout
185 * high level net_prio setting in execution context
187 * Introduce journalctl -b <nr> to show journal messages of a previous boot
189 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
191 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
193 * WorkingDirectory: support env var replacements like in ExecStart= so that people can use $HOME
195 * refuse boot if /etc/machine-id is not useful
197 * nspawn: consider changing users for -u with su, so that NSS resolving works correctly
199 * nspawn: implement personality changes a la linux32(8)
201 * cryptsetup-generator: warn if the password files are world-readable
203 * cryptsetup-generator: add RequiresMountsFor= to cryptseup service files referencing a file, similar for devices
205 * cryptsetup-generator: allow specification of passwords in crypttab itself
207 * document that deps in [Unit] sections ignore Alias= fileds in
208 [Install] units of other units, unless those units are disabled
210 * systemctl: when powering down/suspending check for inhibitors, and warn.
212 * instantiated [Install] for target units
213 https://bugs.freedesktop.org/show_bug.cgi?id=54377
215 * move debug shell to tty6 and make sure this doesn't break the gettys on tty6
217 * move cryptsetup key caching into kernel keyctl?
218 https://bugs.freedesktop.org/show_bug.cgi?id=54982
220 * make nspawn work without terminal
222 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
223 https://bugs.freedesktop.org/show_bug.cgi?id=54712
225 * after deserializing sockets in socket.c we should reapply sockopts and things
227 * make timer units go away after they elapsed
229 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
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 * move keymaps to /usr/lib/... rather than /usr/lib/udev/...
245 * journald: check whether it is OK if the client can still modify delivered journal entries
247 * journal live copy, based on libneon (client) and libmicrohttpd
249 * system-wide seccomp filter
251 * ability to pass fds into systemd
253 * system.conf should have controls for cgroups
255 * bind mount read-only the cgroup tree higher than nspawn
257 * allow writing multiple conditions in unit files on one line
259 * explore multiple service instances per listening socket idea
261 * 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.
263 * shutdown: don't read-only mount anything when running in container
265 * nspawn: --read-only is not applied recursively to submounts
267 * MountFlags=shared acts as MountFlags=slave right now.
269 * ReadOnlyDirectories= is not applied recursively to submounts
271 * drop PID 1 reloading, only do reexecing (difficult: Reload()
272 currently is properly synchronous, Reexec() is weird, because we
273 can't delay the response properly until we are back, so instead of
274 being properly synchronous we just keep open the fd and close it
275 when done. That means clients don't get a successful method reply,
276 but much rather a disconnect on success.
278 * document that service reload may be implemented as service reexec
280 * remember which condition failed for services, not just the fact that something failed
282 * use opterr = 0 for all getopt tools
284 * properly handle loop back mounts via fstab, especially regards to fsck/passno
286 * allow services with no ExecStart= but with an ExecStop=
288 * add proper journal support to "systemctl --user status ..."
290 * add _SYSTEMD_USER_UNIT= field to journal entries
292 * dracut-shutdown needs to be ordered before unmounting /boot
294 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
296 * rename "userspace" to "core-os"
298 * systemctl: "Journal has been rotated since unit was started." message is misleading
300 * syscall filter: add knowledge about compat syscalls
302 * syscall filter: don't enforce no new privs?
304 * syscall filter: option to return EPERM rather than SIGSYS?
306 * syscall filter: port to libseccomp
308 * logind: wakelock/opportunistic suspend support
310 * systemd-analyze post-boot is broken for initrd
312 * systemd-analyze: data collection tools should be lightweight (few dependencies); data analysis tools can be heavyweight
314 * man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
316 * .device aliases need to be implemented with the "following" logic, probably.
318 * refuse taking lower-case variable names in sd_journal_send() and friends.
320 * load-fragment: when loading a unit file via a chain of symlinks
321 verify that it isn't masked via any of the names traversed.
323 * journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
328 * introduce Type=pid-file
330 * maybe allow services with ExecStop= set, but no ExecStart=?
332 * efi: implement /forcefsck as uefi variables thus not requiring file system altering to trigger a file system check
334 * efi: honor language efi variables for default language selection
336 * efi: honor timezone efi variables for default timezone selection
338 * efi: automatically mount EFI partition to /boot if no such entry exists in /etc/fstab and /boot is empty
339 gummiboot exports the EFI system partion (ESP) device:
340 /sys/firmware/efi/vars/LoaderDeviceIdentifier-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
341 Acpi(PNP0A03,0)/Pci(1F|2)/?/HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1)
342 '/' is the separator for the device path list
343 HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1) contains the GPT UUID of the ESP
345 * read the bootloader performance data (raw TSC) in systemd-analyze
346 /sys/firmware/efi/vars/LoaderTicksExec-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
348 /sys/firmware/efi/vars/LoaderTicksInit-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
350 /sys/firmware/efi/vars/LoaderTicksStartMenu-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
351 (only set if the menu was active)
353 * change Requires=basic.target to RequisiteOverride=basic.target
355 * support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
357 * nspawn: make use of device cgroup contrller by default
359 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
361 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
363 * readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
365 * (attempt to) make Debianites happy:
366 - implement .d/ auto includes for unit files
367 - add syntax to reset ExecStart= lists (and similar)
369 * move passno parsing to fstab generator
371 * improve !/proc/*/loginuid situation: make /proc/*/loginuid less dependent on CONFIG_AUDIT,
372 or use the users cgroup information when /proc/*/loginuid is not available.
374 * pam_systemd: try to get old session id from cgroup, if audit sessionid cannot be determined
376 * pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
378 * maybe introduce ~/.config/locale.conf and apply it within PAM
380 * readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
382 * automount: implement expire
384 * logind: auto-suspend, auto-shutdown:
385 IdleAction=(none|suspend|opportunistic|hibernate|poweroff)
387 SessionIdleMode=(explicit|ignore|login)
388 ForceShutdown=(yes|no)
390 * services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)
392 * don't delete /tmp/systemd-namespace-* before a process is gone down
394 * vconsole: implement setterm -store -foreground xxx --background zzz
396 * ExecOnFailure=/usr/bin/foo
398 * fedora: make sshd and pam_loginuid work in nspawn containers
400 * fix utmp for console logins in containers
402 * Add pretty name for seats in logind
404 * ConditionSecurity= should learn about IMA and SMACK
406 * Auke: merge Auke's bootchart
410 * udev systemd unify:

412 - utf8 validator code
414 * udev: scsi_id -> sg3_utils -> kill scsi_id
416 * udev: add trigger --subsystem-match=usb/usb_device device
418 * allow configuration of console width/height in vconsole.conf
420 * cleanup syslog 'priority' vs. 'level' wording
422 * dbus upstream still refers to dbus.target and shouldn't
424 * 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
426 * support container_ttys=
428 * introduce mix of BindTo and Requisite
430 * journalctl: show multiline log messages sanely, expand tabs, and show all valid utf8 messages
432 * add DeleteSocketsOnStop=yes|no option to socket units
434 * journal: store euid in journal if it differs from uid
436 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
438 * journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
440 * add command to systemctl to plot dependency graph as tree (see rhbz 795365)
442 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
444 * default unix qlen is too small (10). bump sysctl? add sockopt?
446 * figure out whether we should leave dbus around during shutdown
448 * dbus: in fedora, make the machine a symlink to /etc/machine-id
450 * dbus: move dbus to early boot
452 * logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
454 * journal: deal nicely with byte-by-byte copied files, especially regards header

460 * save coredump in Windows/Mozilla minidump format
462 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
464 * clean up session cgroups that remain after logout (think sshd), but eventually run empty
466 * support "systemctl stop foobar@.service" to stop all units matching a certain template
468 * logind: allow showing logout dialog from system
470 * document that %% can be used to write % in a string that is specifier extended
472 * when an instanced service exits, remove its parent cgroup too if possible.
474 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
476 * be able to specify a forced restart of service A where service B depends on, in case B
477 needs to be auto-respawned?
479 * Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
481 * when a bus name of a service disappears from the bus make sure to queue further activation requests
483 * something like ConditionExec= or ExecStartPre= without failure state
485 * tmpfiles: apply "x" on "D" too (see patch from William Douglas)
487 * don't set $HOME in services unless requested
489 * hide PAM/TCPWrap options in fragment parser when compile time disabled
491 * when we automatically restart a service, ensure we restart its rdeps, too.
493 * allow Type=simple with PIDFile=
494 https://bugzilla.redhat.com/show_bug.cgi?id=723942
496 * move PAM code into its own binary
498 * logind: spawn user@..service on login
500 * logind: non-local X11 server handling
502 * implement Register= switch in .socket units to enable registration
503 in Avahi, RPC and other socket registration services.
505 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
507 * readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
509 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
511 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
513 * verify that the AF_UNIX sockets of a service in the fs still exist
514 when we start a service in order to avoid confusion when a user
515 assumes starting a service is enough to make it accessible
517 * Make it possible to set the keymap independently from the font on
518 the kernel cmdline. Right now setting one resets also the other.
520 * move nss-myhostname into systemd
522 * and a dbus call to generate target from current state
524 * drop /.readahead on bigger upgrades with yum
526 * add support for /bin/mount -s
528 * GC unreferenced jobs (such as .device jobs)
530 * write blog stories about:
531 - hwdb: what belongs into it, lsusb
532 - enabling dbus services
534 - how to make changes to sysctl and sysfs attributes
536 - how to pass throw-away units to systemd, or dynamically change properties of existing units
537 - how to integrate cgconfig and suchlike with systemd
538 - testing with Harald's awesome test kit
540 - how to develop against journal browsing APIs
541 - the journal HTTP iface
542 - non-cgroup resource management
543 - refreshed, longer missions statement
546 * allow port=0 in .socket units
548 * move readahead files into /var (look for them with .path units?)
550 * teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
552 * support systemd.mask= on the kernel command line.
554 * when key file cannot be found, read it from kbd in cryptsetup
556 * reuse mkdtemp namespace dirs in /tmp?
558 * recreate systemd's D-Bus private socket file on SIGUSR2
560 * Support --test based on current system state
562 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
564 * maybe introduce ExecRestartPre=
566 * configurable jitter for timer events
568 * timer events with system resume
570 * dot output for --test showing the 'initial transaction'
572 * writable cgroups dbus properties for live changes
574 * port over to LISTEN_FDS/LISTEN_PID:
575 - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
579 - libvirtd (/var/run/libvirt/libvirt-sock-ro)
580 - bluetoothd (/var/run/sdp! @/org/bluez/audio!)

585 * io priority during initialization
587 * systemctl list-jobs - show dependencies
589 * add systemctl switch to dump transaction without executing it
591 * drop cap bounding set in readahead and other services
597 - natively watch for dbus-*.service symlinks (PENDING)
598 - allow specification of socket mode/umask when allocating DBusServer
599 - allow disabling of fd passing when connecting a AF_UNIX connection
600 - allow disabling of UID passing for AUTH EXTERNAL
601 - always pass cred data along each message
603 * fix alsa mixer restore to not print error when no config is stored
605 * gnome-shell python script/glxinfo/is-accelerated must die
607 * make cryptsetup lower --iter-time
609 * patch kernel for xattr support in /dev, /proc/, /sys and /sys/fs/cgroup?
611 * NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
612 in an ~30 minutes window. It does not adjust larger differences. Find a way
613 to tell the kernel, to always do a full time sync when the RTC is in UTC and
614 we are in 11-minutes-mode. When we trust the system time to NTP we also want
617 * kernel: add device_type = "fb", "fbcon" to class "graphics"
621 * look for close() vs. close_nointr() vs. close_nointr_nofail()
623 * check for strerror(r) instead of strerror(-r)
625 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
627 * %m in printf() instead of strerror(errno);
631 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
633 * use secure_getenv() instead of getenv() where appropriate
635 Scheduled for removal or fixing:
637 * xxxOverridable dependencies (probably: fix)
639 * support for early-boot SysV services (definitely: remove)
641 * insserv support (definitely: remove)
