3 * Many manager configuration settings that are only applicable to user
4 manager or system manager can be always set. It would be better to reject
5 them when parsing config.
7 * busctl prints errors to stdout:
8 busctl tree org.freedesktop.systemd1 /org/freedesktop/systemd1
12 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
14 * wiki: update journal format documentation for lz4 additions
18 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
20 * rework mount.c and swap.c to follow proper state enumeration/deserialization
21 semantics, like we do for device.c now
25 * All tools that support --root= should also learn --image= so that they can
26 operate on disk images directly. Specifically: bootctl, firstboot, tmpfiles,
27 sysusers, systemctl, repart, journalctl, coredumpctl.
29 * per-service credential system. Specifically: add LoadCredential= (for loading
30 cred from file), AcquireCredential= (for asking user for cred, via
31 ask-password), PassCredential= (for passing on credential systemd itself
32 got). Then, place credentials in a per-service, immutable ramfs instance (so
33 that it cannot be swapped out), destroy after use. Also pass via keyring
34 (with graceful fallback to cover for containers). Define CredentialPath= for
35 defining subdir of /run/credentials/ where to place it. Set $CREDENTIAL_PATH
36 env var for services to the result. Also pass via fd passing (optionally).
38 * homed: add native recovery key support. use 48 lowercase modhex characters
39 (192bit), show qr code of it, include pattern expression in user record.
41 * homed: introduce "degraded" state for home directories that weren't cleanly
42 unmounted (use xattr we add and remove on the loop back file)
44 * homed: during login resize fs automatically towards size goal. Specifically,
45 resize to diskSize if possible, but leave a certain amount (configured by a
46 new value diskLeaveFreeSize) of space free on the backing fs.
48 * homed: permit multiple private keys to be used locally, and pick the right
49 one for signing records automatically depending on a pre-existing signature
51 * homed: add a way to "adopt" a home directory, i.e. strip foreign signatures
52 and insert a local signature instead.
54 * busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
57 * homed: add homed.conf setting DefaultStorage= or so
59 * homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
62 * when systemd-nspawn and suchlike dissect an OS image, and there are multiple
63 root partitions, do an strverscmp() on the partition label and boot
64 first. That is inspired how sd-boot figures out which kernel to boot, and
65 thus allows defining OS images which can be A/B updated and we default to the
66 newest version automatically, both in nspawn and in sd-boot
68 * cryptsetup/homed: also support FIDO2 HMAC password logic for unlocking
69 devices. (see: https://github.com/mjec/fido2-hmac-secret)
71 * systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
74 * homed/userdb: distinguish passwords and recovery keys in the records, since
75 we probably want to use different PBKDF algorithms/settings for them:
76 passwords have low entropy but recovery keys should have good entropy key
77 hence we can make them quicker to work.
80 - teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation
81 - teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host
82 - make it operate on loopback files, dissecting enough to find ESP to operate on
84 * by default, in systemd --user service bump the OOMAdjust to 100, as privs
85 allow so that systemd survives
87 * cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a
88 "base64:" prefix. Useful in particular for pkcs11 mode.
90 * cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use
91 systemd-makefs.service instead.
93 * socket units: allow creating a udev monitor socket with ListenDevices= or so,
94 with matches, then activate app through that passing socket over
97 - port sd_id128_get_machine_app_specific() over from khash
98 - port resolved over from libgcrypt (DNSSEC code)
99 - port journald + fsprg over from libgcrypt
100 - port importd over from libgcrypt
101 - when that's done: kill khash.c
102 - when that's done: kill gnutls support in resolved
104 * kill zenata, all hail weblate?
106 * when we resize disks (homed?) always round up to 4K sectors, not 512K
108 * add growvol and makevol options for /etc/crypttab, similar to
109 x-systemd.growfs and x-systemd-makefs.
111 * hook up the TPM to /etc/crypttab, with a new option that is similar to the
112 new PKCS#11 option in crypttab, and allows unlocking a LUKS volume via a key
113 unsealed from the TPM. Optionally, if TPM is not available fall back to
114 TPM-less mode, and set up linear DM mapping instead (inspired by kpartx), so
115 that the device paths stay the same, regardless if crypto is used or not.
117 * systemd-repart: by default generate minimized partition tables (i.e. tables
118 that only cover the space actually used, excluding any free space at the
119 end), in order to maximize dd'ability. Requires libfdisk work, see
120 https://github.com/karelzak/util-linux/issues/907
122 * systemd-repart: optionally, allow specifying a path to initialize new
123 partitions from, i.e. an fs image file or a source device node. This would
124 then turn systemd-repart into a simple installer: with a few .repart files
125 you could replicate the host system on another device. a full installer would
126 then be: "systemd-repart /dev/sda && bootctl install /dev/sda &&
127 systemd-firstboot --image= …"
129 * systemd-repart: MBR partition table support. Care needs to be taken regarding
130 Type=, so that partition definitions can sanely apply to both the GPT and the
131 MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types
132 for the two partition types explicitly. And provide an internal mapping so
133 that "Type=linux-generic" maps to the right types for both partition tables
136 * systemd-repart: allow sizing partitions as factor of available RAM, so that
137 we can reasonably size swap partitions for hibernation.
139 * systemd-repart: allow running mkfs before making partitions pop up +
140 encryption via LUKS to allow booting into an empty root with only /usr mounted in
142 * systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
144 * systemd-repart: allow disabling growing of specific partitions, or making
145 them (think ESP: we don't ever want to grow it, since we cannot resize vfat)
147 * systemd-repart: add specifier expansion, add especifier that refers to root
148 device node of current system, /usr device node, and matching verity, so that
149 an installer can be made a "copy" installer of the booted OS
151 * systemd-repart: make it a static checker during early boot for existence and
152 absence of other partitions for trusted boot environments
154 * systemd-repart: when no configuration is found, exit early do not check
155 partition table, so that it is safe to run in the initrd on any system
157 * systemd-repart: allow config of partition uuid
159 * systemd-repart: add --make= switch for fallocating a new file of the
160 specified size first.
162 * userdb: allow username prefix searches in varlink API, allow realname and
163 realname substr searches in varlink API
165 * userdb: allow uid/gid range checks
167 * userdb: allow existence checks
169 * pid: activation by journal search expression
171 * when switching root from initrd to host, set the machine_id env var so that
172 if the host has no machine ID set yet we continue to use the random one the
175 * sd-event: add native support for P_ALL waitid() watching, then move PID 1 to
176 it fo reaping assigned but unknown children. This needs to some special care
177 to operate somewhat sensibly in light of priorities: P_ALL will return
178 arbitrary processes, regardless of the priority we want to watch them with,
179 hence on each event loop iteration check all processes which we shall watch
180 with higher prio explicitly, and then watch the entire rest with P_ALL.
182 * tweak sd-event's child watching: keep a prioq of children to watch and use
183 waitid() only on the children with the highest priority until one is waitable
184 and ignore all lower-prio ones from that point on
186 * maybe introduce xattrs that can be set on the root dir of the root fs
187 partition that declare the volatility mode to use the image in. Previously I
188 thought marking this via GPT partition flags but that's not ideal since
189 that's outside of the LUKS encryption/verity verification, and we probably
190 shouldn't operate in a volatile mode unless we got told so from a trusted
193 * figure out automatic partition discovery when combining writable root dir
196 * coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
197 may be used to mark a whole binary as non-coredumpable. Would fix:
198 https://bugs.freedesktop.org/show_bug.cgi?id=69447
200 * teach parse_timestamp() timezones like the calendar spec already knows it
202 * beef up hibernation to optionally do swapon/swapoff immediately before/after
205 * beef up s2h to implement a battery watch loop: instead of entering
206 hibernation unconditionally after coming back from resume make a decision
207 based on the battery load level: if battery level is above a specific
208 threshold, go to suspend again, only hibernate if below it. This means we'd
209 stick to suspend usually, but fall back to hibernation only when battery runs
210 empty (well, subject to our sampling interval). Related to this, check if we
211 can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
212 i.e. see if it can wake up machines from suspend, so that we could resume
213 automatically when the system is low on power and move automatically to
214 hibernation mode. (see
215 https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
217 https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
220 * add an explicit "vertical" mode to format-table, so that "systemctl
221 status"-like outputs (i.e. with a series of field names left and values
222 right) become genuine first class citizens, and we gain automatic, sane JSON
225 * systemd-firstboot: teach it dissector magic, so that you can point it to some
226 disk image and it will just set everything in it all behind the scenes.
228 * systemd-firstboot: add --force mode that replaces existing configuration.
230 * We should probably replace /var/log/README, /etc/rc.d/README with symlinks
231 that are linked to these places instead of copied. After all they are
232 constant vendor data.
234 * maybe add kernel cmdline params: 1) to force first-boot mode + 2) to force
235 random seed crediting
237 * nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
238 so that we make cgroup agent logic safe
240 * nspawn/machined: add API to invoke binary in container, then use that as
241 fallback in "machinectl shell"
243 * logind: rework pam_logind to also do a bus call in case of invocation from
244 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
245 behaviour selectable via pam module option.
248 - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth
249 - hook up machined/nspawn users with a varlink user query interface
250 - rollback when resize fails mid-operation
251 - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid)
253 - shrink fs on logout?
254 - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device.
255 - create on activate?
256 - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls?
257 - communicate clearly when usb stick is safe to remove. probably involves
258 beefing up logind to make pam session close hook synchronous and wait until
259 systemd --user is shut down.
260 - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service
261 - maybe make automatic, read-only, time-based reflink-copies of LUKS disk images (think: time machine)
262 - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory)
263 - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work
264 - fingerprint authentication, pattern authentication, …
265 - make sure "classic" user records can also be managed by homed
266 - description field for groups
267 - make size of $XDG_RUNTIME_DIR configurable in user record
268 - reuse pwquality magic in firstboot
269 - query password from kernel keyring first
270 - update even if record is "absent"
271 - add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends
272 - move acct mgmt stuff from pam_systemd_home to pam_systemd?
273 - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for
274 - make slice for users configurable (requires logind rework)
275 - logind: populate auto-login list bus property from PKCS#11 token
276 - when determining state of a LUKS home directory, check DM suspended sysfs file
278 * introduce a new per-process uuid, similar to the boot id, the machine id, the
279 invocation id, that is derived from process creds, specifically a hashed
280 combination of AT_RANDOM + getpid() + the starttime from
281 /proc/self/status. Then add these ids implicitly when logging. Deriving this
282 uuid from these three things has the benefit that it can be derived easily
283 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
286 * let's not GC a unit while its ratelimits are still pending
288 * when killing due to service watchdog timeout maybe detect whether target
289 process is under ptracing and then log loudly and continue instead.
291 * introduce a new group to own TPM devices
293 * make rfkill uaccess controllable by default, i.e. steal rule from
294 gnome-bluetooth and friends
296 * tweak journald context caching. In addition to caching per-process attributes
297 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
298 keyed by cgroup path, and guarded by ctime changes. This should provide us
299 with a nice speed-up on services that have many processes running in the same
302 * make MAINPID= message reception checks even stricter: if service uses User=,
303 then check sending UID and ignore message if it doesn't match the user or
306 * maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
309 * when importing an fs tree with machined, optionally apply userns-rec-chown
311 * when importing an fs tree with machined, complain if image is not an OS
313 * Maybe introduce a helper safe_exec() or so, which is to execve() which
314 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
315 to 1K implicitly, unless explicitly opted-out.
317 * rework seccomp/nnp logic that even if User= is used in combination with
318 a seccomp option we don't have to set NNP. For that, change uid first whil
319 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
321 * add a concept for automatically loading per-unit secrets off disk and
322 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
323 ConfigurationDirectory=.
325 * when no locale is configured, default to UEFI's PlatformLang variable
327 * bootctl,sd-boot: actually honour the "architecture" key
329 * add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
330 usefaultd() and make systemd-analyze check for it.
332 * paranoia: whenever we process passwords, call mlock() on the memory
333 first. i.e. look for all places we use free_and_erasep() and
334 augment them with mlock(). Also use MADV_DONTDUMP.
336 * Move RestrictAddressFamily= to the new cgroup create socket
338 * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
341 * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
342 log.c and sd-journal-send
344 * optionally: turn on cgroup delegation for per-session scope units
346 * introduce per-unit (i.e. per-slice, per-service) journal log size limits.
348 * sd-boot: automatically load EFI modules from some drop-in dir, so that people
349 can add in file system drivers and such
351 * sd-boot: optionally, show boot menu when previous default boot item has
352 non-zero "tries done" count
354 * introduce an option (or replacement) for "systemctl show" that outputs all
355 properties as JSON, similar to busctl's new JSON output. In contrast to that
356 it should skip the variant type string though.
358 * augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
359 contains some identifier for the project, which allows us to include
360 clickable links to source files generating these log messages. The identifier
361 could be some abberviated URL prefix or so (taking inspiration from Go
362 imports). For example, for systemd we could use
363 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
364 sufficient to build a link by prefixing "http://" and suffixing the
367 * Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
368 make clickable links from log messages carrying a MESSAGE_ID, that lead to
369 some explanatory text online.
371 * maybe extend .path units to expose fanotify() per-mount change events
373 * Add a "systemctl list-units --by-slice" mode or so, which rearranges the
374 output of "systemctl list-units" slightly by showing the tree structure of
375 the slices, and the units attached to them.
377 * the a-posteriori stopping of units bound to units that disappeared logic
378 should be reworked: there should be a queue of units, and we should only
379 enqueue stop jobs from a defer event that processes queue instead of
380 right-away when we find a unit that is bound to one that doesn't exist
381 anymore. (similar to how the stop-unneeded queue has been reworked the same
384 * nspawn: make nspawn suitable for shell pipelines: instead of triggering a
385 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
386 for hangup or ^D before passing on the EOF.
388 * When reloading configuration PID 1 should reset all its properties to the
389 original defaults before calling parse_config()
391 * nspawn: greater control over selinux label?
393 * hibernate/s2h: make this robust and safe to enable in Fedora by default.
396 1. add resume_offset support to the resume code (i.e. support swap files
398 2. check if swap is on weird storage and refuse if so
399 3. add auto-detection of hibernation images
401 * cgroups: use inotify to get notified when somebody else modifies cgroups
402 owned by us, then log a friendly warning.
404 * beef up log.c with support for stripping ANSI sequences from strings, so that
405 it is OK to include them in log strings. This would be particularly useful so
406 that our log messages could contain clickable links for example for unit
407 files and suchlike we operate on.
409 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
411 * add attach --enable and attach --now (for attach+enable+start)
413 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
414 selected user is resolvable in the service even if it ships its own /etc/passwd)
416 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
417 other doesn't. What a disaster. Probably to exclude it. Also
418 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
421 * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
422 usually IN_ATTRIB is the right way to watch deleted files, as the former only
423 fires when a file is actually removed from disk, i.e. the link count drops to
424 zero and is not open anymore, while the latter happens when a file is
425 unlinked from any dir.
427 * port systemctl, busctl, … over to format-table.[ch]'s table formatters
429 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
431 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
433 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
434 files and directories that are left writable for a unit, and which are
435 removed after the unit goes down again. A bit like --ephemeral for
436 systemd-nspawn but for system services. If used together with RootImage= this
437 should reflink the image file itself.
439 Related: add Ephemeral=<path1> <path2> … which would allow marking
440 specific paths only like this.
442 * add CopyFile= or so as unit file setting that may be used to copy files or
443 directory trees from the host to the services RootImage= and RootDirectory=
444 environment. Which we can use for /etc/machine-id and in particular
445 /etc/resolv.conf. Should be smart and do something useful on read-only
446 images, for example fallback to read-only bind mounting the file instead.
448 * show invocation ID in systemd-run output
450 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
452 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
453 and so on, which would mean we could report errors and such.
455 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
458 * introduce DefaultSlice= or so in system.conf that allows changing where we
459 place our units by default, i.e. change system.slice to something
460 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
461 be moved somewhere else too. Finally machined and logind should get similar
462 options so that it is possible to move user session scopes and machines to a
463 different slice too by default. Usecase: people who want to put resources on
464 the entire system, with the exception of one specific service. See:
465 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
467 * maybe rework get_user_creds() to query the user database if $SHELL is used
468 for root, but only then.
470 * be stricter with fds we receive for the fdstore: close them asynchronously
472 * calenderspec: add support for week numbers and day numbers within a
473 year. This would allow us to define "bi-weekly" triggers safely.
475 * sd-bus: add vtable flag, that may be used to request client creds implicitly
476 and asynchronously before dispatching the operation
478 * make use of ethtool veth peer info in machined, for automatically finding out
479 host-side interface pointing to the container.
481 * add some special mode to LogsDirectory=/StateDirectory=… that allows
482 declaring these directories without necessarily pulling in deps for them, or
483 creating them when starting up. That way, we could declare that
484 systemd-journald writes to /var/log/journal, which could be useful when we
485 doing disk usage calculations and so on.
487 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
489 * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
491 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
492 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
493 as the unit is running or has a job queued.
495 * support projid-based quota in machinectl for containers
497 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
498 introduced) as the RTC epoch, instead of the mtime of NEWS.
500 * add a way to lock down cgroup migration: a boolean, which when set for a unit
501 makes sure the processes in it can never migrate out of it
503 * blog about fd store and restartable services
505 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
507 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
508 magic meaning and is no longer upgraded to something else if set explicitly.
510 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
511 make it lose its identity, i.e. be anonymous. For this we'd have to patch
512 through the whole tree to make all code deal with the case where no machine
515 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
516 suitable for processing with rrdtool. Add bus API to access this data, and
517 possibly implement a CPULoad property based on it.
519 * beef up pam_systemd to take unit file settings such as cgroups properties as
522 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
523 the quota of a the user indicated in User= via unit file settings, like the
524 other resource management concepts. Would mix nicely with DynamicUser=1. Or
525 alternatively, do this with projids, so that we can also cover services
526 running as root. Quota should probably cover all the special dirs such as
527 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
528 is set, plus the whole disk space any image configured with RootImage=.
530 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
531 disks to see if the UID is already in use.
533 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
534 for all units. It should be both a way to pin units into memory as well as a
535 wait to retrieve their exit data.
537 * expose IO accounting data on the bus, show it in systemd-run --wait and log
538 about it in the resource log message
540 * show whether a service has out-of-date configuration in "systemctl status" by
541 using mtime data of ConfigurationDirectory=.
543 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
544 creates a static, persistent user rather than a dynamic, transient user. We
545 can leverage code from sysusers.d for this.
547 * add some optional flag to ReadWritePaths= and friends, that has the effect
548 that we create the dir in question when the service is started. Example:
550 ReadWritePaths=:/var/lib/foobar
552 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
553 the sd-journal logging socket, and, if the timeout is set to 0, sets
554 O_NONBLOCK on it. That way people can control if and when to block for
557 * hostnamed: populate form factor data from a new hwdb database, so that old
558 yogas can be recognized as "convertible" too, even if they predate the DMI
559 "convertible" form factor
561 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
562 after all. Be strict however, only support the equivalent of nspawn's
563 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
566 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
567 the service cgroup, which is supposed to monitor the service, and when it
568 exits the service is considered failed by its monitor.
570 * track the per-service PAM process properly (i.e. as an additional control
571 process), so that it may be queried on the bus and everything.
573 * add a new "debug" job mode, that is propagated to unit_start() and for
574 services results in two things: we raise SIGSTOP right before invoking
575 execve() and turn off watchdog support. Then, use that to implement
576 "systemd-gdb" for attaching to the start-up of any system service in its
579 * gpt-auto logic: related to the above, maybe support a "secondary" root
580 partition, that is mounted to / and is writable, and where the actual root's
581 /usr is mounted into.
583 * gpt-auto logic: support encrypted swap, add kernel cmdline option to force it, and honour a gpt bit about it, plus maybe a configuration file
585 * drop nss-myhostname in favour of nss-resolve?
587 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
588 then use that for the setting used in user@.service. It should be understood
589 relative to the configured default value.
591 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
593 * enable LockMLOCK to take a percentage value relative to physical memory
595 * Permit masking specific netlink APIs with RestrictAddressFamily=
597 * nspawn: support that /proc, /sys/, /dev are pre-mounted
599 * define gpt header bits to select volatility mode
601 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
603 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
605 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
607 * ProtectKeyRing= to take keyring calls away
609 * RemoveKeyRing= to remove all keyring entries of the specified user
611 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
612 on PID 1 with the relevant signals, and makes relevant files in /sys and
613 /proc (such as the sysrq stuff) unavailable
615 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
617 * journalctl: make sure -f ends when the container indicated by -M terminates
619 * mount: automatically search for "main" partition of an image has multiple
622 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
623 find a way to map the User=/Group= of the service to the right name. This way
624 a user/group for a service only has to exist on the host for the right
627 * add bus API for creating unit files in /etc, reusing the code for transient units
629 * add bus API to remove unit files from /etc
631 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
633 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
634 kernel doesn't support linkat() that replaces existing files, currently)
636 * transient units: don't bother with actually setting unit properties, we
637 reload the unit file anyway
639 * journald: sigbus API via a signal-handler safe function that people may call
640 from the SIGBUS handler
642 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
644 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
645 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
647 * cache sd_event_now() result from before the first iteration...
649 * PID1: find a way how we can reload unit file configuration for
650 specific units only, without reloading the whole of systemd
652 * add an explicit parser for LimitRTPRIO= that verifies
653 the specified range and generates sane error messages for incorrect
656 * when we detect that there are waiting jobs but no running jobs, do something
658 * push CPUAffinity= also into the "cpuset" cgroup controller
660 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
662 * there's probably something wrong with having user mounts below /sys,
663 as we have for debugfs. for example, src/core/mount.c handles mounts
664 prefixed with /sys generally special.
665 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
667 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
669 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
671 * add a job mode that will fail if a transaction would mean stopping
672 running units. Use this in timedated to manage the NTP service
674 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
676 * The udev blkid built-in should expose a property that reflects
677 whether media was sensed in USB CF/SD card readers. This should then
678 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
679 picked up by systemd unless they contain a medium. This would mirror
680 the behaviour we already have for CD drives.
682 * networkd/udev: implement SR_IOV configuration in .link files:
683 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
685 * hostnamectl: show root image uuid
687 * Find a solution for SMACK capabilities stuff:
688 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
690 * "systemctl preset-all" should probably order the unit files it
691 operates on lexicographically before starting to work, in order to
692 ensure deterministic behaviour if two unit files conflict (like DMs
695 * synchronize console access with BSD locks:
696 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
698 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
699 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
701 * figure out when we can use the coarse timers
703 * add "systemctl start -v foobar.service" that shows logs of a service
704 while the start command runs. This is non-trivial to do without
705 races though, since we should flush out all journal messages before
706 returning from the "systemctl stop".
708 * firstboot: make it useful to be run immediately after yum --installroot to set up a machine. (most specifically, make --copy-root-password work even if /etc/passwd already exists
710 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
712 * maybe allow timer units with an empty Units= setting, so that they
713 can be used for resuming the system but nothing else.
715 * what to do about udev db binary stability for apps? (raw access is not an option)
717 * systemctl: if some operation fails, show log output?
719 * systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #.
720 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
722 * exponential backoff in timesyncd when we cannot reach a server
724 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
726 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
728 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
729 (throughout the codebase, not only PID1)
733 - service registration
734 - service/domain/types browsing
736 - DNS-SD service registration from socket units
737 - resolved should optionally register additional per-interface LLMNR
738 names, so that for the container case we can establish the same name
739 (maybe "host") for referencing the server, everywhere.
740 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
741 - hook up resolved with machined-based address resolution
743 * refcounting in sd-resolve is borked
745 * Add a new verb "systemctl top"
747 * add new gpt type for btrfs volumes
749 * support empty /etc boots nicely:
750 - nspawn/gpt-generator: introduce new gpt partition type for /usr
752 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
754 * a way for container managers to turn off getty starting via $container_headless= or so...
756 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
758 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
759 they run added to the initial transaction and thus confuse Type=idle.
761 * add bus api to query unit file's X fields.
763 * gpt-auto-generator:
764 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
765 - Make /home automount rather than mount?
767 * add generator that pulls in systemd-network from containers when
768 CAP_NET_ADMIN is set, more than the loopback device is defined, even
769 when it is otherwise off
771 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
773 * implement Distribute= in socket units to allow running multiple
774 service instances processing the listening socket, and open this up
777 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
778 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
779 should SIGSTOP all unit processes in a loop until all processes of
780 it are fully stopped. This can later be used for app management by
781 desktop UIs such as gnome-shell to freeze apps that are not visible
782 on screen, not unlike how job control works on the shell
785 - implement per-slice CPUFairScheduling=1 switch
786 - introduce high-level settings for RT budget, swappiness
787 - how to reset dynamically changed unit cgroup attributes sanely?
788 - when reloading configuration, apply new cgroup configuration
789 - when recursively showing the cgroup hierarchy, optionally also show
790 the hierarchies of child processes
793 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
795 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
797 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
799 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
801 * 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
803 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
805 * If we try to find a unit via a dangling symlink, generate a clean
806 error. Currently, we just ignore it and read the unit from the search
809 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
811 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
813 * load .d/*.conf dropins for device units
817 - GetAllProperties() on a non-existing object does not result in a failure currently
818 - port to sd-resolve for connecting to TCP dbus servers
819 - see if we can introduce a new sd_bus_get_owner_machine_id() call to retrieve the machine ID of the machine of the bus itself
820 - see if we can drop more message validation on the sending side
821 - add API to clone sd_bus_message objects
822 - longer term: priority inheritance
824 - NameLost/NameAcquired obsolete
827 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
830 - allow multiple signal handlers per signal?
831 - document chaining of signal handler for SIGCHLD and child handlers
832 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
834 * investigate endianness issues of UUID vs. GUID
836 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
837 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
839 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
841 * add a pam module that on password changes updates any LUKS slot where the password matches
844 - add unit tests for config_parse_device_allow()
846 * seems that when we follow symlinks to units we prefer the symlink
847 destination path over /etc and /usr. We should not do that. Instead
848 /etc should always override /run+/usr and also any symlink
851 * when isolating, try to figure out a way how we implicitly can order
852 all units we stop before the isolating unit...
854 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
856 * Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add
857 ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at
858 https://github.com/systemd/systemd/pull/15109#issuecomment-607740136.
860 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
861 that the boot loader should be installed to the ESP. Define a way
862 how an installer can figure out whether a BLS compliant boot loader
865 * think about requeuing jobs when daemon-reload is issued? usecase:
866 the initrd issues a reload after fstab from the host is accessible
867 and we might want to requeue the mounts local-fs acquired through
870 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
872 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
874 * shutdown logging: store to EFI var, and store to USB stick?
876 * merge unit_kill_common() and unit_kill_context()
879 - honor language efi variables for default language selection (if there are any?)
880 - honor timezone efi variables for default timezone selection (if there are any?)
881 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
883 - recognize the case when not booted on EFI
885 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
887 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
889 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
892 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
893 - logind: wakelock/opportunistic suspend support
894 - Add pretty name for seats in logind
895 - logind: allow showing logout dialog from system?
896 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
897 - if pam_systemd is invoked by su from a process that is outside of a
898 any session we should probably just become a NOP, since that's
899 usually not a real user session but just some system code that just
901 - logind: make the Suspend()/Hibernate() bus calls wait for the for
902 the job to be completed. before returning, so that clients can wait
903 for "systemctl suspend" to finish to know when the suspending is
905 - logind: when the power button is pressed short, just popup a
906 logout dialog. If it is pressed for 1s, do the usual
907 shutdown. Inspiration are Macs here.
908 - expose "Locked" property on logind sesison objects
909 - maybe allow configuration of the StopTimeout for session scopes
910 - rename session scope so that it includes the UID. THat way
911 the session scope can be arranged freely in slices and we don't have
912 make assumptions about their slice anymore.
913 - follow PropertiesChanged state more closely, to deal with quick logouts and
915 - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set
918 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
919 - journald: also get thread ID from client, plus thread name
920 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
921 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
922 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
923 - declare the local journal protocol stable in the wiki interface chart
924 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
925 - journald: when dropping msgs due to ratelimit make sure to write
926 "dropped %u messages" not only when we are about to print the next
927 message that works, but already after a short timeout
928 - check if we can make journalctl by default use --follow mode inside of less if called without args?
929 - maybe add API to send pairs of iovecs via sd_journal_send
930 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
931 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
932 and !FOOBAR for events without FOOBAR.
933 - journal: store timestamp of journal_file_set_offline() int he header,
934 so it is possible to display when the file was last synced.
935 - 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.
936 - journal: find a way to allow dropping history early, based on priority, other rules
937 - journal: When used on NFS, check payload hashes
938 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
939 - refuse taking lower-case variable names in sd_journal_send() and friends.
940 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
941 - journal: deal nicely with byte-by-byte copied files, especially regards header
942 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
943 - Replace utmp, wtmp, btmp, and lastlog completely with journal
944 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
945 - when a kernel driver logs in a tight loop, we should ratelimit that too.
946 - journald: optionally, log debug messages to /run but everything else to /var
947 - journald: when we drop syslog messages because the syslog socket is
948 full, make sure to write how many messages are lost as first thing
949 to syslog when it works again.
950 - journald: allow per-priority and per-service retention times when rotating/vacuuming
951 - journald: make use of uid-range.h to managed uid ranges to split
953 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
954 - improve journalctl performance by loading journal files
955 lazily. Encode just enough information in the file name, so that we
956 do not have to open it to know that it is not interesting for us, for
957 the most common operations.
958 - man: document that corrupted journal files is nothing to act on
959 - rework journald sigbus stuff to use mutex
960 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
961 services that run under their own user ids, and use User= (but only
962 in a world where userns is ubiquitous since otherwise we cannot
963 invoke those daemons on the host AND in a container anymore). Also,
964 if LimitNPROC= is used without User= we should warn and refuse
966 - journalctl --verify: don't show files that are currently being
967 written to as FAIL, but instead show that their are being written to.
968 - add journalctl -H that talks via ssh to a remote peer and passes through
970 - add a version of --merge which also merges /var/log/journal/remote
971 - journalctl: -m should access container journals directly by enumerating
972 them via machined, and also watch containers coming and going.
973 Benefit: nspawn --ephemeral would start working nicely with the journal.
974 - assign MESSAGE_ID to log messages about failed services
976 * add a test if all entries in the catalog are properly formatted.
977 (Adding dashes in a catalog entry currently results in the catalog entry
978 being silently skipped. journalctl --update-catalog must warn about this,
979 and we should also have a unit test to check that all our message are OK.)
982 - document that deps in [Unit] sections ignore Alias= fields in
983 [Install] units of other units, unless those units are disabled
984 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
985 - document that service reload may be implemented as service reexec
986 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
987 - document systemd-journal-flush.service properly
988 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
989 - man: document the very specific env the shutdown drop-in tools live in
990 - man: add more examples to man pages
991 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
992 - document root=gpt-auto properly
995 - add systemctl switch to dump transaction without executing it
996 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
997 - "systemctl disable" on a static unit prints no message and does
998 nothing. "systemctl enable" does nothing, and gives a bad message
999 about it. Should fix both to print nice actionable messages.
1000 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
1001 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
1002 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
1003 - systemctl: "Journal has been rotated since unit was started." message is misleading
1004 - systemctl status output should include list of triggering units and their status
1007 - "systemctl mask" should find all names by which a unit is accessible
1008 (i.e. by scanning for symlinks to it) and link them all to /dev/null
1011 - timer units should get the ability to trigger when:
1013 - Modulate timer frequency based on battery state
1015 * add libsystemd-password or so to query passwords during boot using the password agent logic
1017 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
1019 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
1021 * make repeated alt-ctrl-del presses printing a dump
1023 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
1025 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
1028 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
1029 with seccomp. That should provide us with a useful log buffer that
1030 systemd can log to during early boot, and disconnect container logs
1031 from the kernel's logs.
1032 - as soon as networkd has a bus interface, hook up --network-interface=,
1033 --network-bridge= with networkd, to trigger netdev creation should an
1034 interface be missing
1035 - a nice way to boot up without machine id set, so that it is set at boot
1036 automatically for supporting --ephemeral. Maybe hash the host machine id
1037 together with the machine name to generate the machine id for the container
1038 - fix logic always print a final newline on output.
1039 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
1040 - should optionally support receiving WATCHDOG=1 messages from its payload
1042 - optionally automatically add FORWARD rules to iptables whenever nspawn is
1043 running, remove them when shut down.
1046 - refuse mounting over a mount point
1047 - automatically discover .roothash files in dissect, similarly to nspawn
1050 - add an API so that libvirt-lxc can inform us about network interfaces being
1051 removed or added to an existing machine
1052 - "machinectl migrate" or similar to copy a container from or to a
1053 difference host, via ssh
1054 - introduce systemd-nspawn-ephemeral@.service, and hook it into
1055 "machinectl start" with a new --ephemeral switch
1056 - "machinectl status" should also show internal logs of the container in
1058 - "machinectl history"
1060 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
1061 shell in it, and marks it read-only after use
1064 - cryptsetup-generator: allow specification of passwords in crypttab itself
1065 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
1067 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
1068 https://bugs.freedesktop.org/show_bug.cgi?id=54712
1070 * add a dependency on standard-conf.xml and other included files to man pages
1072 * MountFlags=shared acts as MountFlags=slave right now.
1074 * properly handle loop back mounts via fstab, especially regards to fsck/passno
1076 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
1081 - add trigger --subsystem-match=usb/usb_device device
1082 - reimport udev db after MOVE events for devices without dev_t
1084 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
1086 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
1089 - save coredump in Windows/Mozilla minidump format
1090 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
1092 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
1094 * be able to specify a forced restart of service A where service B depends on, in case B
1095 needs to be auto-respawned?
1098 - apply "x" on "D" too (see patch from William Douglas)
1099 - instead of ignoring unknown fields, reject them.
1100 - creating new directories/subvolumes/fifos/device nodes
1101 should not follow symlinks. None of the other adjustment or creation
1102 calls follow symlinks.
1104 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
1106 * verify that the AF_UNIX sockets of a service in the fs still exist
1107 when we start a service in order to avoid confusion when a user
1108 assumes starting a service is enough to make it accessible
1110 * Make it possible to set the keymap independently from the font on
1111 the kernel cmdline. Right now setting one resets also the other.
1113 * and a dbus call to generate target from current state
1115 * write blog stories about:
1116 - hwdb: what belongs into it, lsusb
1117 - enabling dbus services
1118 - how to make changes to sysctl and sysfs attributes
1120 - how to pass throw-away units to systemd, or dynamically change properties of existing units
1121 - testing with Harald's awesome test kit
1123 - how to develop against journal browsing APIs
1124 - the journal HTTP iface
1125 - non-cgroup resource management
1126 - dynamic resource management with cgroups
1127 - refreshed, longer missions statement
1128 - calendar time events
1129 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
1130 - how to create your own target
1131 - instantiated apache, dovecot and so on
1132 - hooking a script into various stages of shutdown/rearly booot
1134 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
1136 * dot output for --test showing the 'initial transaction'
1139 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
1140 log both units as UNIT=, so that journalctl -u triggers on both.
1141 - generate better errors when people try to set transient properties
1142 that are not supported...
1143 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
1144 - maybe introduce WantsMountsFor=? Usecase:
1145 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
1146 - recreate systemd's D-Bus private socket file on SIGUSR2
1147 - move PAM code into its own binary
1148 - when we automatically restart a service, ensure we restart its rdeps, too.
1149 - hide PAM options in fragment parser when compile time disabled
1150 - Support --test based on current system state
1151 - 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().
1152 - after deserializing sockets in socket.c we should reapply sockopts and things
1153 - drop PID 1 reloading, only do reexecing (difficult: Reload()
1154 currently is properly synchronous, Reexec() is weird, because we
1155 cannot delay the response properly until we are back, so instead of
1156 being properly synchronous we just keep open the fd and close it
1157 when done. That means clients do not get a successful method reply,
1158 but much rather a disconnect on success.
1159 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
1160 - when a bus name of a service disappears from the bus make sure to queue further activation requests
1163 - allow port=0 in .socket units
1164 - maybe introduce ExecRestartPre=
1165 - add ReloadSignal= for configuring a reload signal to use
1166 - implement Register= switch in .socket units to enable registration
1167 in Avahi, RPC and other socket registration services.
1168 - allow Type=simple with PIDFile=
1169 https://bugzilla.redhat.com/show_bug.cgi?id=723942
1170 - allow writing multiple conditions in unit files on one line
1171 - introduce Type=pid-file
1172 - introduce mix of BindTo and Requisite
1173 - add a concept of RemainAfterExit= to scope units
1174 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
1175 - add verification of [Install] section to systemd-analyze verify
1178 - Make sure ID_PATH is always exported and complete for
1179 network devices where possible, so we can safely rely
1183 - add support for more attribute types
1184 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
1187 - add more keys to [Route] and [Address] sections
1188 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
1189 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
1190 - add reduced [Link] support to .network files
1191 - add Scope= parsing option for [Network]
1192 - properly handle routerless dhcp leases
1193 - work with non-Ethernet devices
1194 - add support for more bond options
1195 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
1196 - the DHCP lease data (such as NTP/DNS) is still made available when
1197 a carrier is lost on a link. It should be removed instantly.
1198 - expose in the API the following bits:
1199 - option 15, domain name and/or option 119, search list
1200 - option 12, hostname and/or option 81, fqdn
1201 - option 123, 144, geolocation
1202 - option 252, configure http proxy (PAC/wpad)
1203 - provide a way to define a per-network interface default metric value
1204 for all routes to it. possibly a second default for DHCP routes.
1205 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1206 support Name=foo*|bar*|baz ?
1207 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1208 - allow DUID/IAID to be customized, see issue #394.
1209 - whenever uplink info changes, make DHCP server send out FORCERENEW
1211 * networkd-wait-online:
1212 - make operstates to wait for configurable?
1215 - figure out how much we can increase Maximum Message Size
1218 - add functions to set previously stored IPv6 addresses on startup and get
1219 them at shutdown; store them in client->ia_na
1220 - write more test cases
1221 - implement reconfigure support, see 5.3., 15.11. and 22.20.
1222 - implement support for temporary adressess (IA_TA)
1223 - implement dhcpv6 authentication
1224 - investigate the usefulness of Confirm messages; i.e. are there any
1225 situations where the link changes without any loss in carrier detection
1227 - some servers don't do rapid commit without a filled in IA_NA, verify
1234 - natively watch for dbus-*.service symlinks (PENDING)
1235 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1237 * fix alsa mixer restore to not print error when no config is stored
1239 * make cryptsetup lower --iter-time
1241 * patch kernel for xattr support in /dev, /proc/, /sys?
1243 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1245 * /usr/bin/service should actually show the new command line
1247 * 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=
1249 * fedora: F20: go timer units all the way, leave cron.daily for cron
1251 * neither pkexec nor sudo initialize environ[] from the PAM environment?
1253 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1255 * register catalog database signature as file magic
1257 * zsh shell completion:
1258 - <command> <verb> -<TAB> should complete options, but currently does not
1259 - systemctl add-wants,add-requires
1261 * systemctl status should know about 'systemd-analyze calendar ... --iterations='
1262 * If timer has just OnInactiveSec=..., it should fire after a specified time
1263 after being started.
1267 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1269 * check for strerror(r) instead of strerror(-r)
1273 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1275 * use secure_getenv() instead of getenv() where appropriate
1277 * link up selected blog stories from man pages and unit files Documentation= fields
1278 String is not UTF-8 clean, ignoring assignment
