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 * add a man page "systemdall" that lists all of systemd's man pages, inspired by zsh's "zshall" page
24 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
26 * kernel cmdline switch to turn of predictable network interface names
28 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
30 * udev: remove all (misguided from day 1) userspace firmware_class handling
32 * logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
34 * service: when killing a service with SIGKILL always kill all processes, even if for SIGTERM we only killed the main process
36 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
38 * DeviceAllow/DeviceDeny: disallow everything by default, but whitelist /dev/zero, /dev/null and friends
40 * service: watchdog logic: for testing purposes allow ping, but do not require pong
42 * journald: when dropping msgs due to ratelimit make sure to write
43 "dropped %u messages" not only when we are about to print the next
44 message that works, but alraedy after a short tiemout
46 * journald: also get thread ID from client, plus thread name
48 * check if we can make journalctl by default use --follow mode inside of less if called without args?
50 * Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
52 * journal is not closed properly at shutdown when run in a container?
54 * journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
56 * When shutdown.target is queued begin with an asynchronous sync()?
58 * add API to close/reopen/get fd for journal client fd in libsystemd-journal.
60 * maybe add API to send pairs of iovecs via sd_journal_send
62 * fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
64 * declare the local journal protocol stable in the wiki interface chart
66 * journal: reuse XZ context
68 * sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
70 * introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
72 * timer units should get the ability to trigger when:
73 - CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
76 * update the kernel's TZ (sys_tz) when DST changes
78 * sync down the system time to the RTC when:
79 - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
80 - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
81 This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
82 mode, it will never touch the RTC if the no reliable time source is active or the
83 user did not request anything like it.
85 * When we begin with system shutdown all kind of suspend/hibernation should be prohibited until shutdown/reboot
87 * When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
90 - implement conditional properties (dmi matches)
91 - hwdb --filter=ID_DRIVE_*
92 - find out what to do for blockdevs and skipping scsi modaliases
93 - move writing code to src/libudev/libudev-hwdb-private.c
95 * if booted in "quiet" mode, and an error happens, turn on status output again, so that the emergency mode isn't totally surprising
97 * localectl: add listing support for X11 keymaps, by parsing /usr/share/X11/xkb/rules/xorg.lst
99 * libunwind support for coredump pattern hook, and includes this in
100 the message for coredumps. After all, libunwind is now capable to
101 unwind coredumps since a few weeks ago. This probably requires that
102 we have nice support for multi-line messages on display in logs-show.c.
104 * figure out relation of --all and --full in the various tools
106 * journal: when writing journal auto-rotate if time jumps backwards
108 * introduce new "journal" group in place of adm? introduce groups for the various mini daemons?
110 * journal: add a setgid "adm" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
112 * journactl: support negative filtering, i.e. FOOBAR!="waldo",
113 and !FOOBAR for events without FOOBAR.
115 * print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
117 * add libsystemd-password or so to query passwords during boot using the password agent logic
119 * journal: when rotating, copy over old acls/access mode
121 * journal: document why we do not give ownership to journal files to the user that created them but use FS ACLs for that
123 * journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
125 * 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
127 * 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.
129 * 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().
131 * fedup: add --unit to systemctl switch-root somehow
132 * fedup: don't delete initrd on switch-root
135 * journal: find a way to allow dropping history early, based on priority, other rules
137 * journal: When used on NFS, check payload hashes
139 * journal: When used on NFS make sure wake up sd_journal_wait() every 2s, to handle missing inotify
141 * document that people can use file system ACLs to manage access to journal files, with example
143 * timedated: export boolean that clarifies whether NTP is even available
145 * timedated: refuse time changes when NTP is on
147 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
149 * document unit_name_mangle()
151 * add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
153 * introduce generic AUGMENT_PID=, AUGMENT_DEVICE= fields
155 * deal with sendmail/postfix exclusivity
157 * systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
159 * systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
161 * on shutdown: move utmp, wall, audit logic all into PID 1 itself, get rid of systemd-update-utmp-runlevel
163 * add "provisioning" instructions to setup an empty /etc + /var
164 - used to setup a new container from a shared /usr
165 - superset of tmpfiles model
166 - instructions shipped by packages and stored in /usr/lib/
167 - compose /etc/passwd and /etc/group, copy files
168 - able to create uid + gid used by packages, for file ownership
170 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
171 waiting for the timeout
173 * high level net_prio setting in execution context
175 * Introduce journalctl -b <nr> to show journal messages of a previous boot
177 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
179 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
181 * WorkingDirectory: support env var replacements like in ExecStart= so that people can use $HOME
183 * refuse boot if /etc/machine-id is not useful (or set taint?)
185 * nspawn: consider changing users for -u with su, so that NSS resolving works correctly
187 * nspawn: implement personality changes a la linux32(8)
189 * cryptsetup-generator: warn if the password files are world-readable
191 * cryptsetup-generator: add RequiresMountsFor= to cryptseup service files referencing a file, similar for devices
193 * cryptsetup-generator: allow specification of passwords in crypttab itself
195 * document that deps in [Unit] sections ignore Alias= fileds in
196 [Install] units of other units, unless those units are disabled
198 * systemctl: when powering down/suspending check for inhibitors, and warn.
200 * instantiated [Install] for target units
201 https://bugs.freedesktop.org/show_bug.cgi?id=54377
203 * move debug shell to tty6 and make sure this doesn't break the gettys on tty6
205 * move cryptsetup key caching into kernel keyctl?
206 https://bugs.freedesktop.org/show_bug.cgi?id=54982
208 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
209 https://bugs.freedesktop.org/show_bug.cgi?id=54712
211 * after deserializing sockets in socket.c we should reapply sockopts and things
213 * make timer units go away after they elapsed
215 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
216 (network and remote-fs on shutdown)
218 * come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
220 * journald: add kernel cmdline option to disable ratelimiting for debug purposes
222 * move PID 1 segfaults to /var/lib/systemd/coredump?
224 * Document word splitting syntax for ExecStart= and friends
226 * create /sbin/init symlinks from the build system
228 * Query Paul Moore about relabelling socket fds while they are open
230 * journald: check whether it is OK if the client can still modify delivered journal entries
232 * journal live copy, based on libneon (client) and libmicrohttpd
234 * system-wide seccomp filter
236 * system.conf should have controls for cgroups
238 * bind mount read-only the cgroup tree higher than nspawn
240 * allow writing multiple conditions in unit files on one line
242 * explore multiple service instances per listening socket idea
244 * 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.
246 * shutdown: don't read-only mount anything when running in container
248 * nspawn: --read-only is not applied recursively to submounts
250 * MountFlags=shared acts as MountFlags=slave right now.
252 * ReadOnlyDirectories= is not applied recursively to submounts
254 * drop PID 1 reloading, only do reexecing (difficult: Reload()
255 currently is properly synchronous, Reexec() is weird, because we
256 can't delay the response properly until we are back, so instead of
257 being properly synchronous we just keep open the fd and close it
258 when done. That means clients don't get a successful method reply,
259 but much rather a disconnect on success.
261 * document that service reload may be implemented as service reexec
263 * remember which condition failed for services, not just the fact that something failed
265 * use opterr = 0 for all getopt tools

273 * add _SYSTEMD_USER_UNIT= field to journal entries
275 * dracut-shutdown needs to be ordered before unmounting /boot
277 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
279 * rename "userspace" to "core-os"
281 * systemctl: "Journal has been rotated since unit was started." message is misleading
283 * syscall filter: add knowledge about compat syscalls
285 * syscall filter: don't enforce no new privs?
287 * syscall filter: option to return EPERM rather than SIGSYS?
289 * syscall filter: port to libseccomp
291 * logind: wakelock/opportunistic suspend support
293 * systemd-analyze post-boot is broken for initrd
295 * systemd-analyze: data collection tools should be lightweight (few dependencies); data analysis tools can be heavyweight
297 * man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
299 * .device aliases need to be implemented with the "following" logic, probably.
301 * refuse taking lower-case variable names in sd_journal_send() and friends.
303 * load-fragment: when loading a unit file via a chain of symlinks
304 verify that it isn't masked via any of the names traversed.
306 * journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
311 * introduce Type=pid-file
313 * maybe allow services with ExecStop= set, but no ExecStart=?
315 * efi: implement /forcefsck as uefi variables thus not requiring file system altering to trigger a file system check
317 * efi: honor language efi variables for default language selection
319 * efi: honor timezone efi variables for default timezone selection
321 * efi: automatically mount EFI partition to /boot if no such entry exists in /etc/fstab and /boot is empty
322 gummiboot exports the EFI system partion (ESP) device:
323 /sys/firmware/efi/vars/LoaderDeviceIdentifier-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
324 Acpi(PNP0A03,0)/Pci(1F|2)/?/HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1)
325 '/' is the separator for the device path list
326 HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1) contains the GPT UUID of the ESP
328 * read the bootloader performance data (raw TSC) in systemd-analyze
329 /sys/firmware/efi/vars/LoaderTicksExec-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
331 /sys/firmware/efi/vars/LoaderTicksInit-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
333 /sys/firmware/efi/vars/LoaderTicksStartMenu-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
334 (only set if the menu was active)
336 * change Requires=basic.target to RequisiteOverride=basic.target
338 * support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
340 * nspawn: make use of device cgroup controller by default
342 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
344 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
346 * readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
348 * (attempt to) make Debianites happy:
349 - add syntax to reset ExecStart= lists (and similar)
351 * move passno parsing to fstab generator
353 * improve !/proc/*/loginuid situation: make /proc/*/loginuid less dependent on CONFIG_AUDIT,
354 or use the users cgroup information when /proc/*/loginuid is not available.
356 * pam_systemd: try to get old session id from cgroup, if audit sessionid cannot be determined
358 * pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
360 * maybe introduce ~/.config/locale.conf and apply it within PAM
362 * readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
364 * automount: implement expire
366 * services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)
368 * don't delete /tmp/systemd-namespace-* before a process is gone down
370 * vconsole: implement setterm -store -foreground xxx --background zzz

376 * fix utmp for console logins in containers
378 * Add pretty name for seats in logind
380 * ConditionSecurity= should learn about IMA and SMACK
384 * udev systemd unify:
385 - utf8 validator code
387 * udev: scsi_id -> sg3_utils -> kill scsi_id
389 * udev: add trigger --subsystem-match=usb/usb_device device
391 * allow configuration of console width/height in vconsole.conf
393 * cleanup syslog 'priority' vs. 'level' wording
395 * dbus upstream still refers to dbus.target and shouldn't
397 * 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
399 * support container_ttys=
401 * introduce mix of BindTo and Requisite
403 * journalctl: show multiline log messages sanely, expand tabs, and show all valid utf8 messages
405 * add DeleteSocketsOnStop=yes|no option to socket units
407 * journal: store euid in journal if it differs from uid
409 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
411 * journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
413 * add command to systemctl to plot dependency graph as tree (see rhbz 795365)
415 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
417 * default unix qlen is too small (10). bump sysctl? add sockopt?
419 * figure out whether we should leave dbus around during shutdown
421 * dbus: in fedora, make the machine a symlink to /etc/machine-id
423 * dbus: move dbus to early boot
425 * logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API

431 * document the exit codes when services fail before they are exec()ed
433 * save coredump in Windows/Mozilla minidump format
435 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
437 * clean up session cgroups that remain after logout (think sshd), but eventually run empty
439 * support "systemctl stop foobar@.service" to stop all units matching a certain template
441 * logind: allow showing logout dialog from system
443 * document that %% can be used to write % in a string that is specifier extended
445 * when an instanced service exits, remove its parent cgroup too if possible.
447 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
449 * be able to specify a forced restart of service A where service B depends on, in case B
450 needs to be auto-respawned?
452 * Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
454 * when a bus name of a service disappears from the bus make sure to queue further activation requests
456 * something like ConditionExec= or ExecStartPre= without failure state
458 * tmpfiles: apply "x" on "D" too (see patch from William Douglas)
460 * don't set $HOME in services unless requested
462 * hide PAM/TCPWrap options in fragment parser when compile time disabled
464 * when we automatically restart a service, ensure we restart its rdeps, too.

476 in Avahi, RPC and other socket registration services.
478 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
480 * readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
482 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
484 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
486 * verify that the AF_UNIX sockets of a service in the fs still exist
487 when we start a service in order to avoid confusion when a user
488 assumes starting a service is enough to make it accessible
490 * Make it possible to set the keymap independently from the font on
491 the kernel cmdline. Right now setting one resets also the other.
493 * and a dbus call to generate target from current state
495 * drop /.readahead on bigger upgrades with yum
497 * add support for /bin/mount -s
499 * GC unreferenced jobs (such as .device jobs)
501 * write blog stories about:

503 - enabling dbus services
505 - how to make changes to sysctl and sysfs attributes
507 - how to pass throw-away units to systemd, or dynamically change properties of existing units
508 - how to integrate cgconfig and suchlike with systemd
509 - testing with Harald's awesome test kit
511 - how to develop against journal browsing APIs
512 - the journal HTTP iface
513 - non-cgroup resource management
514 - refreshed, longer missions statement
516 * allow port=0 in .socket units
518 * move readahead files into /var (look for them with .path units?)
520 * teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
522 * support systemd.mask= on the kernel command line.
524 * when key file cannot be found, read it from kbd in cryptsetup
526 * reuse mkdtemp namespace dirs in /tmp?
528 * recreate systemd's D-Bus private socket file on SIGUSR2
530 * Support --test based on current system state
532 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
534 * maybe introduce ExecRestartPre=
536 * configurable jitter for timer events
538 * timer events with system resume
540 * dot output for --test showing the 'initial transaction'
542 * writable cgroups dbus properties for live changes
544 * port over to LISTEN_FDS/LISTEN_PID:
545 - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
549 - libvirtd (/var/run/libvirt/libvirt-sock-ro)

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