2 * sort-out libudev's is_initialized logic for:
4 - is_initialized is true if a database exists
6 - is_initialized is always false; was not supposed to be used here
7 - in-container devices:
8 - is_initialized is always false, because there is no database
10 * enabling an instance unit creates a pointless link, and
11 the unit will be started with getty@getty.service:
12 $ systemctl enable getty@.service
13 ln -s '/usr/lib/systemd/system/getty@.service' '/etc/systemd/system/getty.target.wants/getty@.service'
15 * Dangling symlinks of .automount unit files in .wants/ directories, set up
16 automount points even when the original .automount file did not exist
17 anymore. Only the .mount unit was still around.
19 * properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
21 * When we detect invalid UTF-8, we cannot use it in an error message:
22 log...("Path is not UTF-8 clean, ignoring assignment: %s", rvalue);
24 * shorten the message to sane length:
26 Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory. See system logs and 'systemctl status display-manager.service' for details.
30 * ps should gain colums for slice
32 * Fedora: when installing fedora with yum --installroot /var/run is a directory, not a symlink
33 https://bugzilla.redhat.com/show_bug.cgi?id=975864
35 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
37 * Fedora: post FPC ticket to move add %tmpfiles_create to the packaging guidelines
41 * libsystemd-journal returns the object created as first param in sd_journal_new(), sd_bus_new() and suchlike as last...
44 - implement system-wide DefaultCPUAccounting=1 switch (and similar for blockio, memory?)
45 - implement per-slice CPUFairScheduling=1 switch
46 - handle jointly mounted controllers correctly
47 - introduce high-level settings for RT budget, swappiness
48 - how to reset dynamically changed unit cgroup attributes sanely?
49 - when reloading configuration, apply new cgroup configuration
50 - when recursively showing the cgroup hierarchy, optionally also show
51 the hierarchies of child processes
54 - allow creating auxiliary units with the same call
55 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
56 - ensure scope units may be started only a single time
59 - get rid of readdir_r/dirent_storage stuff, it's unnecessary on Linux
60 - we probably should replace the left-over uses of strv_append() and replace them by strv_push() or strv_extend()
62 * switch to SipHash for hashmaps/sets?
64 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
66 * move libasyncns into systemd as libsystemd-asyncns
68 * machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
70 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
72 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
74 * unify dispatch table in systemctl_main() and friends
76 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
78 * socket-proxyd:Use a nonblocking alternative to getaddrinfo
80 * rfkill,backlight: we probably should run the load tools inside of the udev rules so that the state is properly initialized by the time other software sees it
82 * Add a new Distribute=$NUMBER key to socket units that makes use of SO_REUSEPORT to distribute network traffic on $NUMBER instances
84 * move config_parse_path_strv() out of conf-parser.c
86 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
88 * If we try to find a unit via a dangling symlink, generate a clean
89 error. Currently, we just ignore it and read the unit from the search
92 * When a Type=forking service fails and needed another service, that
93 service is not cleaned up again when it has StopWhenUnneeded=yes
94 http://lists.freedesktop.org/archives/systemd-devel/2013-July/012141.html
96 * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
98 * given that logind/machined now let PID 1 do all nasty work, we can
99 probably reduce the capability set they retain substantially.
101 * btrfs raid assembly: some .device jobs stay stuck in the queue
103 * make sure gdm doesn't use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
105 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
107 * load .d/*.conf dropins for device units
109 * gparted needs to disable auto-activation of mount units somehow, or
110 maybe we should stop doing auto-activation of this after boot
111 entirely. https://bugzilla.gnome.org/show_bug.cgi?id=701676
112 Maybe take a BSD lock at the disk device node and teach udev to
113 check for that and suppress event handling.
115 * document logic of auto/noauto and fail/nofail in fstab in systemd.mount or systemd-fstab-generator man page
117 * something pulls in pcre as shared object dependency into our daemons such as hostnamed.
119 * allow implementation of InaccessibleDirectories=/ plus
120 ReadOnlyDirectories=... for whitelisting files for a service.
123 - when kdbus doesn't take our message without memfds, try again with memfds
124 - implement translator service
125 - implement monitor logic
126 - properly map matches with well-known names against messages with unique names
127 - when triggering property change events, allow a NULL strv indicate that all properties listed as such are send out as changed
128 - see if we can drop more message validation on the sending side
129 - support "const" properties as flag
130 - add API to clone sd_bus_message objects
131 - SD_BUS_COMMENT() macro for inclusion in vtables, syntax inspired by gdbus
132 - sort out error codes for sd_bus_release_name(), distuingish: successful removal from foreign name, from non-existing name
133 - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
134 - kdbus: we need a way to distuingish messages we got due to monitoring from normal messages, since we want to bind methods only to the latter
135 - kdbus: when we do "systemctl daemon-reexec" the call doesn't get properly cancelled
138 * priority inheritance
141 - allow multiple signal handlers per signal?
143 * in the final killing spree, detect processes from the root directory, and
144 complain loudly if they have argv[0][0] == '@' set.
145 https://bugzilla.redhat.com/show_bug.cgi?id=961044
147 * Introduce a way how we can kill the main process of a service with KillSignal, but all processes with SIGKILL later on
148 https://bugzilla.redhat.com/show_bug.cgi?id=952634
150 * maybe add a warning to the unit file parses where the access mode of unit files is nonsensical.
152 * investigate endianness issues of UUID vs. GUID
154 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
155 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
157 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
159 * add a pam module that on password changes updates any LUKS slot where the password matches
161 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
163 * timedatctl, localectl: possibly make some commands work without the daemon, for chroot situations...
165 * timedatectl: print a nicer message when enabling ntp fails because ntpd/chrony are not installed
167 * cgtop: make cgtop useful in a container
170 - add 'set -e' to scripts in test/
171 - make stuff in test/ work with separate output dir
173 * systemctl delete x.snapshot leaves no trace in logs (at least at default level).
175 * make the coredump collector tool move itself into the user's cgroup
176 so that the coredump is properly written to the user's own journal
179 * seems that when we follow symlinks to units we prefer the symlink
180 destination path over /etc and /usr. We shouldn't do that. Instead
181 /etc should always override /run+/usr and also any symlink
184 * when isolating, try to figure out a way how we implicitly can order
185 all units we stop before the isolating unit...
187 * add ConditionArchitecture= or so
189 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
191 * Support SO_REUSEPORT with socket activation:
192 - Let systemd maintain a pool of servers.
193 - Use for seamless upgrades, by running the new server before stopping the
196 * after all byte-wise realloc() is slow, even on glibc, so i guess we
197 need manual exponential loops after all
199 * BootLoaderSpec: drop allowing ext234 for $BOOT. Clarify that the
200 kernel has to be in $BOOT. Clarify that the boot loader should be
201 installed to the ESP. Define a way how an installer can figure out
202 whether a BLS compliant boot loader is installed.
204 * think about requeuing jobs when daemon-reload is issued? usecase:
205 the initrd issues a reload after fstab from the host is accessible
206 and we might want to requeue the mounts local-fs acquired through
209 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
211 * journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
213 * remove any syslog support from log.c -- we probably can't do this before split-off udev is gone for good
215 * shutdown logging: store to EFI var, and store to USB stick?
217 * write UI tool that pops up emergency messages from the journal as notification
219 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
221 * use "log level" rather than "log priority" everywhere
223 * timedate: have global on/off switches for auto-time (NTP), and auto-timezone that connman can subscribe to.
225 * dev-setup.c: when running in a container, create a tiny stub udev
226 database with the systemd tag set for all network interfaces found,
227 so that libudev reports them as present, and systemd's .device units
230 * merge unit_kill_common() and unit_kill_context()
232 * introduce ExecCondition= in services
235 - write man page for efi boot generator
236 - honor language efi variables for default language selection (if there are any?)
237 - honor timezone efi variables for default timezone selection (if there are any?)
238 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
240 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
242 * re-enable "make check" for gtk-doc (broken for unknown reason)
244 * fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
245 https://bugzilla.redhat.com/show_bug.cgi?id=812826
247 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
249 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
252 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
253 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
254 - logind: wakelock/opportunistic suspend support
255 - Add pretty name for seats in logind
256 - logind: allow showing logout dialog from system?
257 - logind: non-local X11 server handling
258 - logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
259 - pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
260 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
261 - when logging out, remove user-owned sysv and posix IPC objects
262 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
263 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
264 - if pam_systemd is invoked by su from a process that is outside of a
265 any session we should probably just become a NOP, since that's
266 usually not a real user session but just some system code that just
269 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
271 * service: watchdog logic: for testing purposes allow ping, but do not require pong
274 - import and delete pstore filesystem content at startup
275 - journald: also get thread ID from client, plus thread name
276 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
277 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
278 - fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
279 - declare the local journal protocol stable in the wiki interface chart
280 - journal: reuse XZ context
281 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
282 - journald: when dropping msgs due to ratelimit make sure to write
283 "dropped %u messages" not only when we are about to print the next
284 message that works, but alraedy after a short tiemout
285 - check if we can make journalctl by default use --follow mode inside of less if called without args?
286 - maybe add API to send pairs of iovecs via sd_journal_send
287 - journal: when writing journal auto-rotate if time jumps backwards
288 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
289 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
290 and !FOOBAR for events without FOOBAR.
291 - journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
292 - 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.
293 - journal: find a way to allow dropping history early, based on priority, other rules
294 - journal: When used on NFS, check payload hashes
295 - journald: check whether it is OK if the client can still modify delivered journal entries
296 - journal live copy, based on libneon (client) and libmicrohttpd (server)
297 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
298 - refuse taking lower-case variable names in sd_journal_send() and friends.
299 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
300 - journal: deal nicely with byte-by-byte copied files, especially regards header
301 - journal: store euid in journal if it differs from uid
302 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
303 - Replace utmp, wtmp, btmp, and lastlog completely with journal
304 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
305 - journalctl: support -M to read journal of containers and determine journal directory from root directory of container
306 - tmpfiles: when applying ownership to /run/log/journal, also do this for the journal fails contained in it
307 - when a kernel driver logs in a tight loop, we should ratelimit that too.
308 - journald: optionally, log debug messages to /run but everything else to /var
309 - journald: when we drop syslog messages because the syslog socket is
310 full, make sure to write how many messages are lost as first thing
311 to syslog when it works again.
312 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
313 - change systemd-journal-flush into a service that stays around during
314 boot, and causes the journal to be moved back to /run on shutdown,
315 so that we don't keep /var busy. This needs to happen synchronously,
316 hence doing this via signals is not going to work.
319 - document that deps in [Unit] sections ignore Alias= fileds in
320 [Install] units of other units, unless those units are disabled
321 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
322 - Document word splitting syntax for ExecStart= and friends
323 - document that units from /etc override those from /usr and /run
324 - document the exit codes when services fail before they are exec()ed
325 - document that service reload may be implemented as service reexec
326 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
327 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
328 - document systemd-journal-flush.service properly
329 - man: remove .include documentation, and instead push people to use .d/*.conf
330 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
331 - man: document the very specific env the shutdown drop-in tools live in
332 - man: extend runlevel(8) to mention that runlevels suck, and are dead. Maybe add runlevel(7) with a note about that too
333 - man: add more examples to man pages
334 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
337 - systemctl list-jobs - show dependencies
338 - add systemctl switch to dump transaction without executing it
339 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
340 - "systemctl disable" on a static unit prints no message and does
341 nothing. "systemctl enable" does nothing, and gives a bad message
342 about it. Should fix both to print nice actionable messages.
343 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
344 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
345 - systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
346 - systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
347 - systemctl: "Journal has been rotated since unit was started." message is misleading
348 - support "systemctl stop foobar@.service" to stop all units matching a certain template
349 - Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
350 - rework wait filter to not require match callback
351 - better error message if you run systemctl without systemd running
352 - systemctl status output should should include list of triggering units and their status
353 - in systemctl list-timers show time trggering units ran last
356 - "systemctl mask" should find all names by which a unit is accessible
357 (i.e. by scanning for symlinks to it) and link them all to /dev/null
358 - "systemctl disable" of a unit instance removes all symlinks, but should
359 only remove the instance symlink (systemctl disable of a template
360 unit however should remove them all).
361 - systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
362 - systemctl: maybe add "systemctl add-wants" or so...
364 * introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
366 * deal with sendmail/postfix exclusivity
369 - timer events with system resume
370 - timer units should get the ability to trigger when:
371 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
373 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
374 - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
375 - when parsing calendar timestamps support the UTC timezone (even if we won't support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
376 - Modulate timer frequency based on battery state
377 - anacron-like feature
379 * update the kernel's TZ (sys_tz) when DST changes
381 * sync down the system time to the RTC when:
382 - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
383 - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
384 This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
385 mode, it will never touch the RTC if the no reliable time source is active or the
386 user did not request anything like it.
388 * if booted in "quiet" mode, and an error happens, turn on status
389 output again, so that the emergency mode isn't totally
390 surprising. Also, terminate plymouth.
392 * libunwind support for coredump pattern hook, and includes this in
393 the message for coredumps. After all, libunwind is now capable to
394 unwind coredumps since a few weeks ago. This probably requires that
395 we have nice support for multi-line messages on display in
396 logs-show.c. Alternatively: use libelfutil, which seems to be the
397 better supported alternative.
399 * add libsystemd-password or so to query passwords during boot using the password agent logic
401 * 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().
403 * fedup: add --unit to systemctl switch-root somehow
404 * fedup: don't delete initrd on switch-root
407 * timedated: refuse time changes when NTP is on
409 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
411 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
413 * add "provisioning" instructions to setup an empty /etc + /var
414 - used to setup a new container from a shared /usr
415 - superset of tmpfiles model
416 - instructions shipped by packages and stored in /usr/lib/
417 - compose /etc/passwd and /etc/group, copy files
418 - able to create uid + gid used by packages, for file ownership
420 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
421 waiting for the timeout
423 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
425 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
428 - nspawn: consider changing users for -u with su, so that NSS resolving works correctly
429 - nspawn: implement personality changes a la linux32(8)
430 - nspawn: --read-only is not applied recursively to submounts
431 - nspawn: make use of device cgroup controller by default
432 - bind mount read-only the cgroup tree higher than nspawn
433 - nspawn: investigate whether we can support the same as LXC's
434 lxc.network.type=phys mode, and pass through entire network
435 interfaces to the container
436 - nspawn: maybe explicitly reset loginuid?
437 - nspawn: make it work for dwalsh and shared /usr containers -- tmpfs mounts as command line parameters, selinux exec context
438 - refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
439 - add an option to nspawn that uses seccomp to make socket(AF_NETLINK,
440 SOCK_RAW, NETLINK_AUDIT) fail the the appropriate error code that
441 makes the audit userspace to think auditing is not available in the
443 - support taking a btrfs snapshot at startup and dropping it afterwards
446 - cryptsetup-generator: allow specification of passwords in crypttab itself
447 - move cryptsetup key caching into kernel keyctl?
448 https://bugs.freedesktop.org/show_bug.cgi?id=54982
449 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
451 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
452 https://bugs.freedesktop.org/show_bug.cgi?id=54712
454 * after deserializing sockets in socket.c we should reapply sockopts and things
456 * make timer units go away after they elapsed
458 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
459 (network and remote-fs on shutdown)
461 * come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
463 * move PID 1 segfaults to /var/lib/systemd/coredump?
465 * create /sbin/init symlinks from the build system
467 * Query Paul Moore about relabelling socket fds while they are open
469 * allow writing multiple conditions in unit files on one line
471 * explore multiple service instances per listening socket idea
473 * shutdown: don't read-only mount anything when running in container
475 * MountFlags=shared acts as MountFlags=slave right now.
477 * ReadOnlyDirectories= is not applied recursively to submounts
479 * drop PID 1 reloading, only do reexecing (difficult: Reload()
480 currently is properly synchronous, Reexec() is weird, because we
481 can't delay the response properly until we are back, so instead of
482 being properly synchronous we just keep open the fd and close it
483 when done. That means clients don't get a successful method reply,
484 but much rather a disconnect on success.
486 * properly handle loop back mounts via fstab, especially regards to fsck/passno
488 * allow services with no ExecStart= but with an ExecStop=
490 * dracut-shutdown needs to be ordered before unmounting /boot
492 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
494 * rename "userspace" to "core-os"
497 - syscall filter: add knowledge about compat syscalls
498 - syscall filter: don't enforce no new privs?
499 - syscall filter: option to return EPERM rather than SIGSYS?
500 - syscall filter: port to libseccomp
501 - system-wide seccomp filter
503 * load-fragment: when loading a unit file via a chain of symlinks
504 verify that it isn't masked via any of the names traversed.
506 * introduce Type=pid-file
508 * change Requires=basic.target to RequisiteOverride=basic.target
510 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
512 * automount: implement expire:
513 - set superblock timeout AUTOFS_DEV_IOCTL_TIMEOUT_CMD
514 - periodically run AUTOFS_DEV_IOCTL_EXPIRE_CMD
515 - every timeout/4 (original autofs logic)
516 - blocking, needs a thread
518 - receive expire packet on pipe if kernel tells the timeout is over
520 - answer expire packet on pipe with AUTOFS_DEV_IOCTL_{READY,FAIL}_CMD
521 - AUTOFS_DEV_IOCTL_EXPIRE_CMD returns
523 * ExecOnFailure=/usr/bin/foo
526 - remove src/udev/udev-builtin-firmware.c (CONFIG_FW_LOADER_USER_HELPER=n)
529 - add trigger --subsystem-match=usb/usb_device device
531 * cleanup syslog 'priority' vs. 'level' wording
533 * 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
535 * introduce mix of BindTo and Requisite
537 * add DeleteSocketsOnStop=yes|no option to socket units
539 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
541 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
543 * default unix qlen is too small (10). bump sysctl? add sockopt?
545 * save coredump in Windows/Mozilla minidump format
547 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
549 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
551 * be able to specify a forced restart of service A where service B depends on, in case B
552 needs to be auto-respawned?
554 * when a bus name of a service disappears from the bus make sure to queue further activation requests
557 - check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar
558 - apply "x" on "D" too (see patch from William Douglas)
560 * for services: don't set $HOME in services unless requested
562 * hide PAM/TCPWrap options in fragment parser when compile time disabled
564 * when we automatically restart a service, ensure we restart its rdeps, too.
566 * allow Type=simple with PIDFile=
567 https://bugzilla.redhat.com/show_bug.cgi?id=723942
569 * move PAM code into its own binary
571 * implement Register= switch in .socket units to enable registration
572 in Avahi, RPC and other socket registration services.
574 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
576 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
578 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
580 * verify that the AF_UNIX sockets of a service in the fs still exist
581 when we start a service in order to avoid confusion when a user
582 assumes starting a service is enough to make it accessible
584 * support User= and Group= attributes for AF_UNIX sockets. (difficult, requires NSS from PID 1?)
586 * Make it possible to set the keymap independently from the font on
587 the kernel cmdline. Right now setting one resets also the other.
589 * and a dbus call to generate target from current state
592 - drop /.readahead on bigger upgrades with yum
593 - move readahead files into /var (look for them with .path units?)
594 - readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
595 - readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
596 - readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
598 * add support for /bin/mount -s
600 * GC unreferenced jobs (such as .device jobs)
602 * write blog stories about:
603 - hwdb: what belongs into it, lsusb
604 - enabling dbus services
606 - how to make changes to sysctl and sysfs attributes
608 - how to pass throw-away units to systemd, or dynamically change properties of existing units
609 - how to integrate cgconfig and suchlike with systemd
610 - testing with Harald's awesome test kit
612 - how to develop against journal browsing APIs
613 - the journal HTTP iface
614 - non-cgroup resource management
615 - dynamic resource management with cgroups
616 - refreshed, longer missions statement
617 - calendar time events
618 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
619 - how to create your own target
620 - instantiated apache, dovecot and so on
621 - hooking a script into various stages of shutdown/rearly booot
623 * allow port=0 in .socket units
625 * support systemd.mask= on the kernel command line.
627 * recreate systemd's D-Bus private socket file on SIGUSR2
629 * Support --test based on current system state
631 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
633 * maybe introduce ExecRestartPre=
635 * dot output for --test showing the 'initial transaction'
637 * port over to LISTEN_FDS/LISTEN_PID:
640 - libvirtd (/var/run/libvirt/libvirt-sock-ro)
641 - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
644 * fingerprint.target, wireless.target, gps.target, netdevice.target
646 * io priority during initialization
648 * drop cap bounding set in readahead and other services
651 - figure out a simple way to wait for journal events in a way that
653 - add documentation to systemd.daemon
656 - plot per-process IO utilization
657 - group processes based on service association (cgroups)
658 - document initcall_debug
659 - kernel cmdline "bootchart" option for simplicity?
662 - Make sure ID_PATH is always exported and complete for
663 network devices where possible, so we can safely rely
665 - Check if Driver= is broken, or just my driver (bcma)
668 - replace sd_rtnl_message_append() by type-safe versions
669 - improve container support, and add support for entering containers when reading
670 - add support for more attribute types
673 - unify and clarify logging, also use proper structured log messages
674 - add [Route] sections
675 - add more keys to [Address] sections
676 - add DHCPv4 support (and, longer term, other kinds of dynamic config)
677 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
682 - natively watch for dbus-*.service symlinks (PENDING)
683 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
685 * fix alsa mixer restore to not print error when no config is stored
687 * make cryptsetup lower --iter-time
689 * patch kernel for xattr support in /dev, /proc/, /sys?
691 * NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
692 in an ~30 minutes window. It does not adjust larger differences. Find a way
693 to tell the kernel, to always do a full time sync when the RTC is in UTC and
694 we are in 11-minutes-mode. When we trust the system time to NTP we also want
697 * kernel: add device_type = "fb", "fbcon" to class "graphics"
699 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
701 * dbus upstream still refers to dbus.target and shouldn't
703 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
705 * add "# export SYSTEMD_PAGER=" to bash login
707 * /usr/bin/service should actually show the new command line
709 * fedora: suggest auto-restart on failure, but not on success and not on coredump. also, ask people to think about changing the start limit logic. Also point people to RestartPreventExitStatus=, SuccessExitStatus=
711 * fedora: F20: go timer units all the way, leave cron.daily for cron
713 * neither pkexec nor sudo initialize environ[] from the PAM environment?
715 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
719 * look for close() vs. close_nointr() vs. close_nointr_nofail()
721 * check for strerror(r) instead of strerror(-r)
723 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
727 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
729 * use secure_getenv() instead of getenv() where appropriate
731 * link up selected blog stories from man pages and unit files Documentation= fields
733 Scheduled for removal or fixing:
735 * xxxOverridable dependencies (probably: fix)
