2 * enabling an instance unit creates a pointless link, and
3 the unit will be started with getty@getty.service:
4 $ systemctl enable getty@.service
5 ln -s '/usr/lib/systemd/system/getty@.service' '/etc/systemd/system/getty.target.wants/getty@.service'
7 * check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar
9 * swap units that are activated by one name but shown in the kernel under another are semi-broken
11 * Dangling symlinks of .automount unit files in .wants/ directories, set up
12 automount points even when the original .automount file did not exist
13 anymore. Only the .mount unit was still around.
15 * properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
17 * When we detect invalid UTF-8, we cannot use it in an error message:
18 log...("Path is not UTF-8 clean, ignoring assignment: %s", rvalue);
20 * shorten the message to sane length:
22 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.
26 * external: ps should gain colums for slice
29 - localectl: support new converted x11→console keymaps
31 * when installing fedora with yum --installroot /var/run is a directory, not a symlink
32 https://bugzilla.redhat.com/show_bug.cgi?id=975864
34 CGroup Rework Completion:
36 * implement system-wide DefaultCPUAccounting=1 switch (and similar for blockio, memory?)
38 * implement per-slice CPUFairScheduling=1 switch
40 * handle jointly mounted controllers correctly
42 * introduce high-level settings for RT budget, swappiness
46 * general: get rid of readdir_r/dirent_storage stuff, it's unnecessary on Linux
48 * add API to clone sd_bus_message objects
50 * sd-bus: synthesized messages should get serial number (uint32_t) -1
52 * sd-event: allow multiple signal handlers per signal
54 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
56 * move libasyncns into systemd as libsystemd-asyncns
58 * calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
60 * sd-bus: when triggering property change events, allow a NULL strv indicate that all properties listed as such are send out as changed
62 * sd-bus: enforce signatures on response messages
64 * sd-bus: see if we can drop more message validation on the sending side
66 * sd-bus: introduce sd_bus_creds object and attach it to messages as well as allow querying it for names
68 * sd-bus: support "const" properties as flag
70 * sd-event: when a handler returns an error, just turn off its event
71 source, but do not return anything up to the event loop
72 caller. Instead add parameter to sd_event_request_quit() to take
73 retval. This way errors rippling upwards are the option, not the
76 * sd-event: child pid handling: first invoke waitid(WNOHANG) and call event handler, only afterwards reap the process
78 * sd-event: native support for watchdog stuff
80 * machined, localed: when we try to kill an empty cgroup, generate an ESRCH call over the bus
82 * sd-bus: SD_BUS_COMMENT() macro for inclusion in vtables, syntax inspired by gdbus
84 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
86 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
88 * add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
90 * systemctl: rework wait filter to not require match callback
92 * unify dispatch table in systemctl_main() and friends
94 * bus: access policy as vtable flag
96 * journalctl: support -M to read journal of containers and determine journal directory from root directory of container
98 * tmpfiles: to make sure we don't delete unpacked tarballs with old timestamps right-away never delete stuff that is inside a directory with a new mtime
100 * "systemctl mask" should find all names by which a unit is accessible
101 (i.e. by scanning for symlinks to it) and link them all to /dev/null
103 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
105 * remove NSS usage from PID 1 (notably the specifiers)
108 - Support multiple inherited sockets mapped to different remote hosts
109 - Use a nonblocking alternative to getaddrinfo
111 * "systemctl cat" or "systemctl view" command or or so, that cats the backing unit file of a service, plus its drop-ins and shows them in a pager
113 * 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
115 * Add a new Distribute=$NUMBER key to socket units that makes use of SO_REUSEPORT to distribute network traffic on $NUMBER instances
117 * tmpfiles: when applying ownership to /run/log/journal, also do this for the journal fails contained in it
119 * we probably should replace the left-over uses of strv_append() and replace them by strv_push() or strv_extend()
121 * move config_parse_path_strv() out of conf-parser.c
123 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
125 * If we try to find a unit via a dangling symlink, generate a clean
126 error. Currently, we just ignore it and read the unit from the search
129 * When a Type=forking service fails and needed another service, that
130 service is not cleaned up again when it has StopWhenUnneeded=yes
131 http://lists.freedesktop.org/archives/systemd-devel/2013-July/012141.html
133 * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
135 * ensure scope units may be started only a single time
137 * better error message if you run systemctl without systemd running
139 * systemctl status output should should include list of triggering units and their status
141 * for transient units, instead of writing out drop-ins for all properties consider serializing them in the normal serialization stream
143 * logind: when logging out, remove user-owned sysv and posix IPC objects
145 * session scopes/user unit: add RequiresMountsFor for the home directory of the user
147 * add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
149 * journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
151 * given that logind/machined now let PID 1 do all nasty work, we can
152 probably reduce the capability set they retain substantially.
154 * btrfs raid assembly: some .device jobs stay stuck in the queue
156 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
158 * Fedora: post FPC ticket to move add %tmpfiles_create to the packaging guidelines
160 * make sure gdm doesn't use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
162 * 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
164 * when a kernel driver logs in a tight loop, we should ratelimit that too.
166 * "systemctl disable" of a unit instance removes all symlinks, but should
167 only remove the instance symlink (systemctl disable of a template
168 unit however should remove them all).
170 * journald: optionally, log debug messages to /run but everything else to /var
172 * systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
174 * journald: when we drop syslog messages because the syslog socket is
175 full, make sure to write how many messages are lost as first thing
176 to syslog when it works again.
178 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
180 * load .d/*.conf dropins for device units
182 * service_coldplug() appears to reinstall the wrong stop timeout watch.
184 * transient units: allow creating auxiliary units with the same call
186 * how to reset dynamically changed attributes sanely?
188 * when reloading configuration, apply new cgroup configuration
190 * journald: make sure ratelimit is actually really per-service with the new cgroup changes
192 * gparted needs to disable auto-activation of mount units somehow, or
193 maybe we should stop doing auto-activation of this after boot
194 entirely. https://bugzilla.gnome.org/show_bug.cgi?id=701676
195 Maybe take a BSD lock at the disk device node and teach udev to
196 check for that and suppress event handling.
198 * when recursively showing the cgroup hierarchy, optionally also show
199 the hierarchies of child processes
201 * document logic of auto/noauto and fail/nofail in fstab in systemd.mount or systemd-fstab-generator man page
203 * something pulls in pcre as shared object dependency into our daemons such as hostnamed.
205 * document systemd-journal-flush.service properly
207 * change systemd-journal-flush into a service that stays around during
208 boot, and causes the journal to be moved back to /run on shutdown,
209 so that we don't keep /var busy. This needs to happen synchronously,
210 hence doing this via signals is not going to work.
212 * allow implementation of InaccessibleDirectories=/ plus
213 ReadOnlyDirectories=... for whitelisting files for a service.
216 - default policy (allow uid == 0 and our own uid)
217 - enforce alignment of pointers passed in
218 - when kdbus doesn't take our message without memfds, try again with memfds
219 - implement translator service
220 - port systemd to new library
221 - implement busname unit type in systemd
223 - merge busctl into systemctl or so?
224 - synthesize sd_bus_message objects from kernel messages
225 - properly implement name registry ioctls for kdbus
226 - implement monitor logic
227 - properly map matches with well-known names against messages with unique names
230 * priority inheritance
232 * in the final killing spree, detect processes from the root directory, and
233 complain loudly if they have argv[0][0] == '@' set.
234 https://bugzilla.redhat.com/show_bug.cgi?id=961044
236 * add an option to nspawn that uses seccomp to make socket(AF_NETLINK,
237 SOCK_RAW, NETLINK_AUDIT) fail the the appropriate error code that
238 makes the audit userspace to think auditing is not available in the
241 * Introduce a way how we can kill the main process of a service with KillSignal, but all processes with SIGKILL later on
242 https://bugzilla.redhat.com/show_bug.cgi?id=952634
244 * maybe add a warning to the unit file parses where the access mode of unit files is nonsensical.
246 * investigate endianness issues of UUID vs. GUID
248 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
249 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
251 * if pam_systemd is invoked by su from a process that is outside of a
252 any session we should probably just become a NOP, since that's
253 usually not a real user session but just some system code that just
256 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
258 * add a pam module that on password changes updates any LUKS slot where the password matches
260 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
262 * timedatctl, localectl: possibly make some commands work without the daemon, for chroot situations...
264 * logind: add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
266 * cgtop: make cgtop useful in a container
269 - add 'set -e' to scripts in test/
270 - make stuff in test/ work with separate output dir
271 - qemu wrapper script: http://www.spinics.net/lists/kvm/msg72389.html
273 * systemctl delete x.snapshot leaves no trace in logs (at least at default level).
275 * make the coredump collector tool move itself into the user's cgroup
276 so that the coredump is properly written to the user's own journal
279 * seems that when we follow symlinks to units we prefer the symlink
280 destination path over /etc and /usr. We shouldn't do that. Instead
281 /etc should always override /run+/usr and also any symlink
284 * when isolating, try to figure out a way how we implicitly can order
285 all units we stop before the isolating unit...
287 * add ConditionArchitecture= or so
289 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
291 * Support SO_REUSEPORT with socket activation:
292 - Let systemd maintain a pool of servers.
293 - Use for seamless upgrades, by running the new server before stopping the
296 * after all byte-wise realloc() is slow, even on glibc, so i guess we
297 need manual exponential loops after all
299 * BootLoaderSpec: drop allowing ext234 for $BOOT. Clarify that the
300 kernel has to be in $BOOT. Clarify that the boot loader should be
301 installed to the ESP. Define a way how an installer can figure out
302 whether a BLS compliant boot loader is installed.
304 * man: remove .include documentation, and instead push people to use .d/*.conf
306 * think about requeuing jobs when daemon-reload is issued? usecase:
307 the initrd issues a reload after fstab from the host is accessible
308 and we might want to requeue the mounts local-fs acquired through
311 * rework specifier logic so that we can distinguish OOM errors from other errors
313 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
315 * journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
317 * remove any syslog support from log.c -- we probably can't do this before split-off udev is gone for good
319 * documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
321 * add a tool that lists active timer units plus their next elapse and the time the units ran last
323 * man: document the very specific env the shutdown drop-in tools live in
325 * shutdown logging: store to EFI var, and store to USB stick?
327 * man: extend runlevel(8) to mention that runlevels suck, and are dead. Maybe add runlevel(7) with a note about that too
329 * systemctl: maybe add "systemctl add-wants" or so...
331 * man: add more examples to man pages
333 * man: maybe sort directives in man pages, and take sections from --help and apply them to man too
335 * write UI tool that pops up emergency messages from the journal as notification
337 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
339 * msgcatalog determine default language of entries from the catalog
340 file name. i.e. foobar.de_DE.catalog would set the default entry
341 name for the entries to de_DE if they aren't explicitly suffixed
344 * use "log level" rather than "log priority" everywhere
346 * timedate: have global on/off switches for auto-time (NTP), and auto-timezone that connman can subscribe to.
348 * dev-setup.c: when running in a container, create a tiny stub udev
349 database with the systemd tag set for all network interfaces found,
350 so that libudev reports them as present, and systemd's .device units
353 * merge unit_kill_common() and unit_kill_context()
355 * introduce ExecCondition= in services
358 - write man page for efi boot generator
359 - honor language efi variables for default language selection (if there are any?)
360 - honor timezone efi variables for default timezone selection (if there are any?)
361 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
363 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
365 * re-enable "make check" for gtk-doc (broken for unknown reason)
367 * fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
368 https://bugzilla.redhat.com/show_bug.cgi?id=812826
370 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
372 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
375 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
376 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
377 - logind: wakelock/opportunistic suspend support
378 - Add pretty name for seats in logind
379 - logind: allow showing logout dialog from system?
380 - logind: non-local X11 server handling
381 - logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
382 - pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
383 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
385 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
387 * service: watchdog logic: for testing purposes allow ping, but do not require pong
390 - import and delete pstore filesystem content at startup
391 - journald: also get thread ID from client, plus thread name
392 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
393 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
394 - fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
395 - declare the local journal protocol stable in the wiki interface chart
396 - journal: reuse XZ context
397 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
398 - journald: when dropping msgs due to ratelimit make sure to write
399 "dropped %u messages" not only when we are about to print the next
400 message that works, but alraedy after a short tiemout
401 - check if we can make journalctl by default use --follow mode inside of less if called without args?
402 - maybe add API to send pairs of iovecs via sd_journal_send
403 - journal: when writing journal auto-rotate if time jumps backwards
404 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
405 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
406 and !FOOBAR for events without FOOBAR.
407 - journal: when rotating, copy over old acls/access mode
408 - journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
409 - 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.
410 - journal: find a way to allow dropping history early, based on priority, other rules
411 - journal: When used on NFS, check payload hashes
412 - journald: check whether it is OK if the client can still modify delivered journal entries
413 - journal live copy, based on libneon (client) and libmicrohttpd (server)
414 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
415 - refuse taking lower-case variable names in sd_journal_send() and friends.
416 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
417 - journal: deal nicely with byte-by-byte copied files, especially regards header
418 - journalctl: expand tabs
419 - journal: store euid in journal if it differs from uid
420 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
421 - Replace utmp, wtmp, btmp, and lastlog completely with journal
422 - Port upower to use the journal for historical power information used in future calculations
425 - document unit_name_mangle()
426 - document that deps in [Unit] sections ignore Alias= fileds in
427 [Install] units of other units, unless those units are disabled
428 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
429 - Document word splitting syntax for ExecStart= and friends
430 - document that units from /etc override those from /usr and /run
431 - document the exit codes when services fail before they are exec()ed
432 - document that service reload may be implemented as service reexec
433 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
436 - systemctl list-jobs - show dependencies
437 - add systemctl switch to dump transaction without executing it
438 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
439 - "systemctl disable" on a static unit prints no message and does
440 nothing. "systemctl enable" does nothing, and gives a bad message
441 about it. Should fix both to print nice actionable messages.
442 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
443 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
444 - systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
445 - systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
446 - systemctl: "Journal has been rotated since unit was started." message is misleading
447 - support "systemctl stop foobar@.service" to stop all units matching a certain template
448 - Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
450 * introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
452 * deal with sendmail/postfix exclusivity
455 - timer events with system resume
456 - timer units should get the ability to trigger when:
457 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
459 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
460 - Modulate timer frequency based on battery state
461 - anacron-like feature
463 * update the kernel's TZ (sys_tz) when DST changes
465 * sync down the system time to the RTC when:
466 - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
467 - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
468 This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
469 mode, it will never touch the RTC if the no reliable time source is active or the
470 user did not request anything like it.
472 * if booted in "quiet" mode, and an error happens, turn on status
473 output again, so that the emergency mode isn't totally
474 surprising. Also, terminate plymouth.
476 * libunwind support for coredump pattern hook, and includes this in
477 the message for coredumps. After all, libunwind is now capable to
478 unwind coredumps since a few weeks ago. This probably requires that
479 we have nice support for multi-line messages on display in
480 logs-show.c. Alternatively: use libelfutil, which seems to be the
481 better supported alternative.
483 * figure out relation of --all and --full in the various tools
485 * add libsystemd-password or so to query passwords during boot using the password agent logic
487 * 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().
489 * fedup: add --unit to systemctl switch-root somehow
490 * fedup: don't delete initrd on switch-root
494 - timedated: refuse time changes when NTP is on
496 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
498 * introduce generic AUGMENT_PID=, AUGMENT_DEVICE= fields
500 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
502 * add "provisioning" instructions to setup an empty /etc + /var
503 - used to setup a new container from a shared /usr
504 - superset of tmpfiles model
505 - instructions shipped by packages and stored in /usr/lib/
506 - compose /etc/passwd and /etc/group, copy files
507 - able to create uid + gid used by packages, for file ownership
509 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
510 waiting for the timeout
512 * high level net_prio setting in execution context
514 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
516 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
518 * refuse boot if /etc/machine-id is not useful (or set taint?)
521 - nspawn: consider changing users for -u with su, so that NSS resolving works correctly
522 - nspawn: implement personality changes a la linux32(8)
523 - nspawn: --read-only is not applied recursively to submounts
524 - nspawn: make use of device cgroup controller by default
525 - bind mount read-only the cgroup tree higher than nspawn
526 - nspawn: investigate whether we can support the same as LXC's
527 lxc.network.type=phys mode, and pass through entire network
528 interfaces to the container
529 - nspawn: maybe add a way to drop additional caps, in addition to add additional caps
530 - nspawn: maybe explicitly reset loginuid?
531 - nspawn: make it work for dwalsh and shared /usr containers -- tmpfs mounts as command line parameters, selinux exec context
532 - refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
535 - cryptsetup-generator: allow specification of passwords in crypttab itself
536 - move cryptsetup key caching into kernel keyctl?
537 https://bugs.freedesktop.org/show_bug.cgi?id=54982
538 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
540 * move debug shell to tty6 and make sure this doesn't break the gettys on tty6
542 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
543 https://bugs.freedesktop.org/show_bug.cgi?id=54712
545 * after deserializing sockets in socket.c we should reapply sockopts and things
547 * make timer units go away after they elapsed
549 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
550 (network and remote-fs on shutdown)
552 * come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
554 * move PID 1 segfaults to /var/lib/systemd/coredump?
556 * create /sbin/init symlinks from the build system
558 * Query Paul Moore about relabelling socket fds while they are open
560 * allow writing multiple conditions in unit files on one line
562 * explore multiple service instances per listening socket idea
564 * shutdown: don't read-only mount anything when running in container
566 * MountFlags=shared acts as MountFlags=slave right now.
568 * ReadOnlyDirectories= is not applied recursively to submounts
570 * drop PID 1 reloading, only do reexecing (difficult: Reload()
571 currently is properly synchronous, Reexec() is weird, because we
572 can't delay the response properly until we are back, so instead of
573 being properly synchronous we just keep open the fd and close it
574 when done. That means clients don't get a successful method reply,
575 but much rather a disconnect on success.
577 * use opterr = 0 for all getopt tools
579 * properly handle loop back mounts via fstab, especially regards to fsck/passno
581 * allow services with no ExecStart= but with an ExecStop=
583 * dracut-shutdown needs to be ordered before unmounting /boot
585 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
587 * rename "userspace" to "core-os"
590 - syscall filter: add knowledge about compat syscalls
591 - syscall filter: don't enforce no new privs?
592 - syscall filter: option to return EPERM rather than SIGSYS?
593 - syscall filter: port to libseccomp
594 - system-wide seccomp filter
596 * .device aliases need to be implemented with the "following" logic, probably.
598 * load-fragment: when loading a unit file via a chain of symlinks
599 verify that it isn't masked via any of the names traversed.
601 * introduce Type=pid-file
603 * change Requires=basic.target to RequisiteOverride=basic.target
605 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
607 * automount: implement expire:
608 - set superblock timeout AUTOFS_DEV_IOCTL_TIMEOUT_CMD
609 - periodically run AUTOFS_DEV_IOCTL_EXPIRE_CMD
610 - every timeout/4 (original autofs logic)
611 - blocking, needs a thread
613 - receive expire packet on pipe if kernel tells the timeout is over
615 - answer expire packet on pipe with AUTOFS_DEV_IOCTL_{READY,FAIL}_CMD
616 - AUTOFS_DEV_IOCTL_EXPIRE_CMD returns
618 * services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)
620 * ExecOnFailure=/usr/bin/foo
623 - remove src/udev/udev-builtin-firmware.c (CONFIG_FW_LOADER_USER_HELPER=n)
626 - add trigger --subsystem-match=usb/usb_device device
628 * cleanup syslog 'priority' vs. 'level' wording
630 * 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
632 * support container_ttys=
634 * introduce mix of BindTo and Requisite
636 * add DeleteSocketsOnStop=yes|no option to socket units
638 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
640 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
642 * default unix qlen is too small (10). bump sysctl? add sockopt?
644 * save coredump in Windows/Mozilla minidump format
646 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
648 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
650 * be able to specify a forced restart of service A where service B depends on, in case B
651 needs to be auto-respawned?
653 * when a bus name of a service disappears from the bus make sure to queue further activation requests
655 * tmpfiles: apply "x" on "D" too (see patch from William Douglas)
657 * for services: don't set $HOME in services unless requested
659 * hide PAM/TCPWrap options in fragment parser when compile time disabled
661 * when we automatically restart a service, ensure we restart its rdeps, too.
663 * allow Type=simple with PIDFile=
664 https://bugzilla.redhat.com/show_bug.cgi?id=723942
666 * move PAM code into its own binary
668 * implement Register= switch in .socket units to enable registration
669 in Avahi, RPC and other socket registration services.
671 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
673 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
675 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
677 * verify that the AF_UNIX sockets of a service in the fs still exist
678 when we start a service in order to avoid confusion when a user
679 assumes starting a service is enough to make it accessible
681 * support User= and Group= attributes for AF_UNIX sockets.
683 * Make it possible to set the keymap independently from the font on
684 the kernel cmdline. Right now setting one resets also the other.
686 * and a dbus call to generate target from current state
689 - drop /.readahead on bigger upgrades with yum
690 - move readahead files into /var (look for them with .path units?)
691 - readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
692 - readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
693 - readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
695 * add support for /bin/mount -s
697 * GC unreferenced jobs (such as .device jobs)
699 * write blog stories about:
700 - hwdb: what belongs into it, lsusb
701 - enabling dbus services
703 - how to make changes to sysctl and sysfs attributes
705 - how to pass throw-away units to systemd, or dynamically change properties of existing units
706 - how to integrate cgconfig and suchlike with systemd

716 - how to create your own target
717 - instantiated apache, dovecot and so on
718 - hooking a script into various stages of shutdown/rearly booot
720 * allow port=0 in .socket units
722 * support systemd.mask= on the kernel command line.
724 * recreate systemd's D-Bus private socket file on SIGUSR2
726 * Support --test based on current system state
728 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
730 * maybe introduce ExecRestartPre=
732 * dot output for --test showing the 'initial transaction'
734 * port over to LISTEN_FDS/LISTEN_PID:
735 - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
739 - libvirtd (/var/run/libvirt/libvirt-sock-ro)
740 - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
743 * fingerprint.target, wireless.target, gps.target, netdevice.target
745 * io priority during initialization
747 * drop cap bounding set in readahead and other services
750 - figure out a simple way to wait for journal events in a way that
752 - add documentation to systemd.daemon
755 - plot per-process IO utilization
756 - group processes based on service association (cgroups)
757 - document initcall_debug
758 - kernel cmdline "bootchart" option for simplicity?
761 - Make sure ID_PATH is always exported and complete for
762 network devices where possible, so we can safely rely
764 - Check if Driver= is broken, or just my driver (bcma)
767 - replace sd_rtnl_message_append() by type-safe versions
768 - improve container support, and add support for entering containers when reading
769 - add support for more attribute types
775 - natively watch for dbus-*.service symlinks (PENDING)
776 - allow specification of socket mode/umask when allocating DBusServer
777 - allow disabling of fd passing when connecting a AF_UNIX connection
778 - allow disabling of UID passing for AUTH EXTERNAL
779 - always pass cred data along each message
780 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
782 * fix alsa mixer restore to not print error when no config is stored
784 * make cryptsetup lower --iter-time
786 * patch kernel for xattr support in /dev, /proc/, /sys?
788 * NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
789 in an ~30 minutes window. It does not adjust larger differences. Find a way
790 to tell the kernel, to always do a full time sync when the RTC is in UTC and
791 we are in 11-minutes-mode. When we trust the system time to NTP we also want
794 * kernel: add device_type = "fb", "fbcon" to class "graphics"
796 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
798 * dbus upstream still refers to dbus.target and shouldn't
800 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
802 * add "# export SYSTEMD_PAGER=" to bash login
804 * /usr/bin/service should actually show the new command line
806 * 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=
808 * fedora: F20: go timer units all the way, leave cron.daily for cron
810 * neither pkexec nor sudo initialize environ[] from the PAM environment?
812 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
816 * look for close() vs. close_nointr() vs. close_nointr_nofail()
818 * check for strerror(r) instead of strerror(-r)
820 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
824 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
826 * use secure_getenv() instead of getenv() where appropriate
828 * link up selected blog stories from man pages and unit files Documentation= fields
830 Scheduled for removal or fixing:
832 * xxxOverridable dependencies (probably: fix)
