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 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
24 * udev: remove all (misguided from day 1) userspace firmware_class handling
26 * logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
28 * service: when killing a service with SIGKILL always kill all processes, even if for SIGTERM we only killed the main process
30 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
32 * DeviceAllow/DeviceDeny: disallow everything by default, but whitelist /dev/zero, /dev/null and friends
34 * service: watchdog logic: for testing purposes allow ping, but do not require pong
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 * journald: also get thread ID from client, plus thread name
42 * check if we can make journalctl by default use --follow mode inside of less if called without args?
44 * Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
46 * journal is not closed properly at shutdown when run in a container?
48 * journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
50 * When shutdown.target is queued begin with an asynchronous sync()?
52 * add API to close/reopen/get fd for journal client fd in libsystemd-journal.
54 * maybe add API to send pairs of iovecs via sd_journal_send
56 * fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
58 * declare the local journal protocol stable in the wiki interface chart
60 * journal: reuse XZ context
62 * sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
64 * introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
66 * timer units should get the ability to trigger when:
67 - CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
70 * update the kernel's TZ (sys_tz) when DST changes
72 * sync down the system time to the RTC when:
73 - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
74 - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
75 This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
76 mode, it will never touch the RTC if the no reliable time source is active or the
77 user did not request anything like it.
79 * When we begin with system shutdown all kind of suspend/hibernation should be prohibited until shutdown/reboot
81 * When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
84 - implement conditional properties (dmi matches)
85 - hwdb --filter=ID_DRIVE_*
86 - find out what to do for blockdevs and skipping scsi modaliases
87 - move writing code to src/libudev/libudev-hwdb-private.c
89 * if booted in "quiet" mode, and an error happens, turn on status output again, so that the emergency mode isn't totally surprising
91 * localectl: add listing support for X11 keymaps, by parsing /usr/share/X11/xkb/rules/xorg.lst
93 * libunwind support for coredump pattern hook, and includes this in
94 the message for coredumps. After all, libunwind is now capable to
95 unwind coredumps since a few weeks ago. This probably requires that
96 we have nice support for multi-line messages on display in logs-show.c.
98 * figure out relation of --all and --full in the various tools
100 * journal: when writing journal auto-rotate if time jumps backwards
102 * introduce new "journal" group in place of adm? introduce groups for the various mini daemons?
104 * journal: add a setgid "adm" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
106 * journactl: support negative filtering, i.e. FOOBAR!="waldo",
107 and !FOOBAR for events without FOOBAR.
109 * print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
111 * add libsystemd-password or so to query passwords during boot using the password agent logic
113 * journal: when rotating, copy over old acls/access mode
115 * journal: document why we do not give ownership to journal files to the user that created them but use FS ACLs for that
117 * journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
119 * 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
121 * 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.
123 * 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().
125 * fedup: add --unit to systemctl switch-root somehow
126 * fedup: don't delete initrd on switch-root
129 * journal: find a way to allow dropping history early, based on priority, other rules
131 * journal: When used on NFS, check payload hashes
133 * journal: When used on NFS make sure wake up sd_journal_wait() every 2s, to handle missing inotify
135 * document that people can use file system ACLs to manage access to journal files, with example
137 * timedated: export boolean that clarifies whether NTP is even available
139 * timedated: refuse time changes when NTP is on
141 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
143 * document unit_name_mangle()
145 * add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
147 * introduce generic AUGMENT_PID=, AUGMENT_DEVICE= fields
149 * deal with sendmail/postfix exclusivity
151 * systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
153 * systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
155 * on shutdown: move utmp, wall, audit logic all into PID 1 itself, get rid of systemd-update-utmp-runlevel
157 * add "provisioning" instructions to setup an empty /etc + /var
158 - used to setup a new container from a shared /usr
159 - superset of tmpfiles model
160 - instructions shipped by packages and stored in /usr/lib/
161 - compose /etc/passwd and /etc/group, copy files
162 - able to create uid + gid used by packages, for file ownership
164 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
165 waiting for the timeout
167 * high level net_prio setting in execution context
169 * Introduce journalctl -b <nr> to show journal messages of a previous boot
171 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
173 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
175 * WorkingDirectory: support env var replacements like in ExecStart= so that people can use $HOME
177 * refuse boot if /etc/machine-id is not useful (or set taint?)
179 * nspawn: consider changing users for -u with su, so that NSS resolving works correctly
181 * nspawn: implement personality changes a la linux32(8)
183 * cryptsetup-generator: warn if the password files are world-readable
185 * cryptsetup-generator: add RequiresMountsFor= to cryptseup service files referencing a file, similar for devices
187 * cryptsetup-generator: allow specification of passwords in crypttab itself
189 * document that deps in [Unit] sections ignore Alias= fileds in
190 [Install] units of other units, unless those units are disabled
192 * systemctl: when powering down/suspending check for inhibitors, and warn.
194 * instantiated [Install] for target units
195 https://bugs.freedesktop.org/show_bug.cgi?id=54377
197 * move debug shell to tty6 and make sure this doesn't break the gettys on tty6
199 * move cryptsetup key caching into kernel keyctl?
200 https://bugs.freedesktop.org/show_bug.cgi?id=54982
202 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
203 https://bugs.freedesktop.org/show_bug.cgi?id=54712
205 * after deserializing sockets in socket.c we should reapply sockopts and things
207 * make timer units go away after they elapsed
209 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
210 (network and remote-fs on shutdown)
212 * come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
214 * journald: add kernel cmdline option to disable ratelimiting for debug purposes
216 * move PID 1 segfaults to /var/lib/systemd/coredump?
218 * Document word splitting syntax for ExecStart= and friends
220 * create /sbin/init symlinks from the build system
222 * Query Paul Moore about relabelling socket fds while they are open
224 * journald: check whether it is OK if the client can still modify delivered journal entries
226 * journal live copy, based on libneon (client) and libmicrohttpd
228 * system-wide seccomp filter
230 * system.conf should have controls for cgroups
232 * bind mount read-only the cgroup tree higher than nspawn
234 * allow writing multiple conditions in unit files on one line
236 * explore multiple service instances per listening socket idea
238 * 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.
240 * shutdown: don't read-only mount anything when running in container
242 * nspawn: --read-only is not applied recursively to submounts
244 * MountFlags=shared acts as MountFlags=slave right now.
246 * ReadOnlyDirectories= is not applied recursively to submounts
248 * drop PID 1 reloading, only do reexecing (difficult: Reload()
249 currently is properly synchronous, Reexec() is weird, because we
250 can't delay the response properly until we are back, so instead of
251 being properly synchronous we just keep open the fd and close it
252 when done. That means clients don't get a successful method reply,
253 but much rather a disconnect on success.
255 * document that service reload may be implemented as service reexec
257 * remember which condition failed for services, not just the fact that something failed
259 * use opterr = 0 for all getopt tools
261 * properly handle loop back mounts via fstab, especially regards to fsck/passno
263 * allow services with no ExecStart= but with an ExecStop=
265 * add proper journal support to "systemctl --user status ..."
267 * add _SYSTEMD_USER_UNIT= field to journal entries
269 * dracut-shutdown needs to be ordered before unmounting /boot
271 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
273 * rename "userspace" to "core-os"
275 * systemctl: "Journal has been rotated since unit was started." message is misleading
277 * syscall filter: add knowledge about compat syscalls
279 * syscall filter: don't enforce no new privs?
281 * syscall filter: option to return EPERM rather than SIGSYS?
283 * syscall filter: port to libseccomp
285 * logind: wakelock/opportunistic suspend support
287 * systemd-analyze post-boot is broken for initrd
289 * systemd-analyze: data collection tools should be lightweight (few dependencies); data analysis tools can be heavyweight
291 * man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
293 * .device aliases need to be implemented with the "following" logic, probably.
295 * refuse taking lower-case variable names in sd_journal_send() and friends.
297 * load-fragment: when loading a unit file via a chain of symlinks
298 verify that it isn't masked via any of the names traversed.
300 * journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
305 * introduce Type=pid-file
307 * maybe allow services with ExecStop= set, but no ExecStart=?
309 * efi: implement /forcefsck as uefi variables thus not requiring file system altering to trigger a file system check
311 * efi: honor language efi variables for default language selection
313 * efi: honor timezone efi variables for default timezone selection
315 * efi: automatically mount EFI partition to /boot if no such entry exists in /etc/fstab and /boot is empty
316 gummiboot exports the EFI system partion (ESP) device:
317 /sys/firmware/efi/vars/LoaderDeviceIdentifier-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
318 Acpi(PNP0A03,0)/Pci(1F|2)/?/HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1)
319 '/' is the separator for the device path list
320 HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1) contains the GPT UUID of the ESP
322 * read the bootloader performance data (raw TSC) in systemd-analyze
323 /sys/firmware/efi/vars/LoaderTicksExec-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
325 /sys/firmware/efi/vars/LoaderTicksInit-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
327 /sys/firmware/efi/vars/LoaderTicksStartMenu-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
328 (only set if the menu was active)
330 * change Requires=basic.target to RequisiteOverride=basic.target
332 * support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
334 * nspawn: make use of device cgroup controller by default
336 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
338 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
340 * readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
342 * (attempt to) make Debianites happy:
343 - implement .d/ auto includes for unit files
344 - add syntax to reset ExecStart= lists (and similar)
346 * move passno parsing to fstab generator
348 * improve !/proc/*/loginuid situation: make /proc/*/loginuid less dependent on CONFIG_AUDIT,
349 or use the users cgroup information when /proc/*/loginuid is not available.
351 * pam_systemd: try to get old session id from cgroup, if audit sessionid cannot be determined
353 * pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
355 * maybe introduce ~/.config/locale.conf and apply it within PAM
357 * readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
359 * automount: implement expire
361 * services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)
363 * don't delete /tmp/systemd-namespace-* before a process is gone down
365 * vconsole: implement setterm -store -foreground xxx --background zzz
367 * ExecOnFailure=/usr/bin/foo
369 * fedora: make sshd and pam_loginuid work in nspawn containers

373 * Add pretty name for seats in logind
375 * ConditionSecurity= should learn about IMA and SMACK
377 * Auke: merge Auke's bootchart
381 * udev systemd unify:
382 - strpcpy(), strpcpyl(), strscpy(), strscpyl()
383 - utf8 validator code
385 * udev: scsi_id -> sg3_utils -> kill scsi_id
387 * udev: add trigger --subsystem-match=usb/usb_device device
389 * allow configuration of console width/height in vconsole.conf
391 * cleanup syslog 'priority' vs. 'level' wording
393 * dbus upstream still refers to dbus.target and shouldn't
395 * 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
397 * support container_ttys=
399 * introduce mix of BindTo and Requisite
401 * journalctl: show multiline log messages sanely, expand tabs, and show all valid utf8 messages
403 * add DeleteSocketsOnStop=yes|no option to socket units
405 * journal: store euid in journal if it differs from uid
407 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
409 * journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
411 * add command to systemctl to plot dependency graph as tree (see rhbz 795365)
413 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
415 * default unix qlen is too small (10). bump sysctl? add sockopt?
417 * figure out whether we should leave dbus around during shutdown
419 * dbus: in fedora, make the machine a symlink to /etc/machine-id
421 * dbus: move dbus to early boot
423 * logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
425 * journal: deal nicely with byte-by-byte copied files, especially regards header
427 * journal: local deserializer of export mode, http server
429 * document the exit codes when services fail before they are exec()ed
431 * save coredump in Windows/Mozilla minidump format
433 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
435 * clean up session cgroups that remain after logout (think sshd), but eventually run empty
437 * support "systemctl stop foobar@.service" to stop all units matching a certain template
439 * logind: allow showing logout dialog from system
441 * document that %% can be used to write % in a string that is specifier extended
443 * when an instanced service exits, remove its parent cgroup too if possible.
445 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
447 * be able to specify a forced restart of service A where service B depends on, in case B
448 needs to be auto-respawned?
450 * Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
452 * when a bus name of a service disappears from the bus make sure to queue further activation requests
454 * something like ConditionExec= or ExecStartPre= without failure state
456 * tmpfiles: apply "x" on "D" too (see patch from William Douglas)
458 * don't set $HOME in services unless requested
460 * hide PAM/TCPWrap options in fragment parser when compile time disabled
462 * when we automatically restart a service, ensure we restart its rdeps, too.

465 https://bugzilla.redhat.com/show_bug.cgi?id=723942
467 * move PAM code into its own binary
469 * logind: spawn user@..service on login
471 * logind: non-local X11 server handling
473 * implement Register= switch in .socket units to enable registration
474 in Avahi, RPC and other socket registration services.
476 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
478 * readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
480 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
482 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
484 * verify that the AF_UNIX sockets of a service in the fs still exist
485 when we start a service in order to avoid confusion when a user
486 assumes starting a service is enough to make it accessible
488 * Make it possible to set the keymap independently from the font on
489 the kernel cmdline. Right now setting one resets also the other.
491 * and a dbus call to generate target from current state
493 * drop /.readahead on bigger upgrades with yum
495 * add support for /bin/mount -s
497 * GC unreferenced jobs (such as .device jobs)
499 * write blog stories about:
500 - hwdb: what belongs into it, lsusb
501 - enabling dbus services
503 - how to make changes to sysctl and sysfs attributes
505 - how to pass throw-away units to systemd, or dynamically change properties of existing units
506 - how to integrate cgconfig and suchlike with systemd
507 - testing with Harald's awesome test kit
509 - how to develop against journal browsing APIs
510 - the journal HTTP iface
511 - non-cgroup resource management
512 - refreshed, longer missions statement
515 * allow port=0 in .socket units
517 * move readahead files into /var (look for them with .path units?)
519 * teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
521 * support systemd.mask= on the kernel command line.
523 * when key file cannot be found, read it from kbd in cryptsetup
525 * reuse mkdtemp namespace dirs in /tmp?
527 * recreate systemd's D-Bus private socket file on SIGUSR2
529 * Support --test based on current system state
531 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
533 * maybe introduce ExecRestartPre=
535 * configurable jitter for timer events
537 * timer events with system resume
539 * dot output for --test showing the 'initial transaction'
541 * writable cgroups dbus properties for live changes
543 * port over to LISTEN_FDS/LISTEN_PID:
544 - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
548 - libvirtd (/var/run/libvirt/libvirt-sock-ro)
549 - bluetoothd (/var/run/sdp! @/org/bluez/audio!)

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