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 * userdbctl: "Password OK: yes" is shown even when there are no passwords
8 or the password is locked.
12 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
16 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
18 * rework mount.c and swap.c to follow proper state enumeration/deserialization
19 semantics, like we do for device.c now
23 * expose MS_NOSYMFOLLOW in various places
25 * tpm2: support a PIN policy, i.e. allowing windows-style short authentication
26 passwords by using the TPM2 to enforce ratelimiting and such, use for
29 * Add concept for upgrading TPM2 enrollments, maybe a new switch
30 --pcrs=4:<hash> or so, i.e. select a PCR to include in the hash, and then
33 * homed: store PKCS#11 + FIDO2 token info in LUKS2 header, compatible with
34 systemd-cryptsetup, so that it can unlock homed volumes
36 * cryptenroll: politely refuse enrolling new keys to homed volumes, since we
37 we cannot update identity info
39 * TPM2: auto-reenroll in cryptsetup, as fallback for hosed firmware upgrades
42 * cryptsetup: if only recovery keys are registered and no regular passphrases,
43 ask user for "recovery key", not "passphrase"
45 * cyptsetup: add option for automatically removing empty password slot on boot
47 * cryptsetup: optionally, when run during boot-up and password is never
48 entered, and we are on battery power (or so), power off machine again
50 * cryptsetup: when FIDO2/PKCS#11/TPM2 token/chip didn't show up after some
51 time, abort the attempt, fallback to asking for pw
53 * cryptsetup: when waiting for FIDO2/PKCS#11 token, tell plymouth that, and
54 allow plymouth to abort the waiting and enter pw instead
56 * when configuring loopback netif, and it fails due to EPERM, eat up error if
57 it happens to be set up alright already.
59 * at boot: check if battery above some threshold, if not power off again after explanation
61 * userdb: add field for ambient caps, so that a user can have CAP_WAKE_ALARM
62 for example. And add code that resets ambient caps for all services by
65 * homed: try to unmount in regular intervals when home dir was busy when we
68 * sd-bus: when connecting to some dbus server socker, set originating AF_UNIX
69 socket name in abstract namespace to include "description" string, and pick
70 it up from there in sd_bus_creds logic. i.e. we can use the socket peer
71 address as conduit for some minimal connection metainfo, and use it to
72 restore the "description" logic that kdbus used to have.
74 * teach LoadCredential= the ability to load all files from a specified dir as
77 * systemd-analyze netif that explains predictable interface (or networkctl)
79 * port selinux code from mallinfo() to mallinfo2() once added to glibc
81 * Add service setting to run a service within the specified VRF. i.e. do the
82 equivalent of "ip vrf exec".
84 * export action of device object on sd-device, so that monitor becomes useful
86 * add root=tmpfs that mounts a tmpfs to /sysroot (to be used in combination
87 with usr=…, for a similar effect as systemd.volatile=yes but without the
88 "hide-out" effect). Also, add root=gpt-auto-late support or so, that is like
89 root=gpt-auto but initially mounts a tmpfs to /sysroot, and then revisits
90 later after systemd-repart ran. Usecase: let's ship images with only /usr
91 partition, then on first boot create the root partition. In this case we want
92 to read the repart data from /usr before the root partition exists. Add
93 usr=gpt-auto that automatically finds a /usr partition.
95 * change SwitchRoot() implementation in PID 1 to use pivot_root(".", "."), as
96 documented in the pivot_root(2) man page, so that we can drop the /oldroot
99 * special case some calls of chase_symlinks() to use openat2() internally, so
100 that the kernel does what we otherwise do.
102 * homed: keep an fd to the homedir open at all times, to keep the fs pinned
103 (autofs and such) while user is logged in.
105 * nss-systemd: also synthesize shadow records for users/groups
107 * make use of new glibc 2.32 APIs sigabbrev_np() and strerrorname_np().
109 * when main nspawn supervisor process gets suspended due to SIGSTOP/SIGTTOU or
110 so, freeze the payload too.
112 * repart: support setting up dm-integrity with HMAC
114 * add /etc/integritytab, to support dm-integrity setups. In particular those
115 with HMAC as hash function, so that we can have a protected /home without
116 encryption (leaving encryption to the individual dirs/homed).
118 * complement root=, rootflags=, rootfstype= with rootsubdir= which allows
119 mounting a subdir of the root fs as actual root. This can be used as
120 fstype-agnostic version of btrfs' rootflags=subvol=foobar.
122 * if /usr/bin/swapoff fails due to OOM, log a friendly explanatory message about it
124 * build short web pages out of each catalog entry, build them along with man
125 pages, and include hyperlinks to them in the journal output
127 * machined: add API to acquire UID range. add API to mount/dissect loopback
128 file. Both protected by PK. Then make nspawn use these APIs to run
129 unprivileged containers. i.e. push the truly privileged bits into machined,
130 so that the client side can remain entirely unprivileged, with SUID or
133 * journald: do journal file writing out-of-process, with one writer process per
134 client UID, so that synthetic hash table collisions can slow down a specific
135 user's journal stream down but not the others.
137 * nspawn: support time namespaces
139 * systemd-firstboot: make sure to always use chase_symlinks() before
140 reading/writing files
142 * Remove any support for booting without /usr pre-mounted in the initrd entirely.
143 Update INITRD_INTERFACE.md accordingly.
145 * pid1: Move to tracking of main pid/control pid of units per pidfd
147 * pid1: support new clone3() fork-into-cgroup feature
149 * pid1: also remove PID files of a service when the service starts, not just
152 * make us use dynamically fewer deps for containers in general purpose distros:
153 o turn into dlopen() deps:
155 - p11-kit-trust (always)
156 - kmod-libs (only when called from PID 1)
157 - libblkid (only in RootImage= handling in PID 1, but not elsewhere)
158 - libpam (only when called from PID 1)
159 - bzip2, xz, lz4 (always — gzip and zstd should probably stay static deps the way they are,
160 since they are so basic and our defaults)
161 o move into separate libsystemd-shared-iptables.so .so
162 - iptables-libs (only used by nspawn + networkd)
164 * seccomp: maybe use seccomp_merge() to merge our filters per-arch if we can.
165 Apparently kernel performance is much better with fewer larger seccomp
166 filters than with more smaller seccomp filters.
168 * systemd-path: add ESP and XBOOTLDR path. Add "private" runtime/state/cache dir enum,
169 mapping to $RUNTIME_DIRECTORY, $STATE_DIRECTORY and such
171 * All tools that support --root= should also learn --image= so that they can
172 operate on disk images directly. Specifically: bootctl, systemctl,
173 coredumpctl. (Already done: systemd-nspawn, systemd-firstboot,
174 systemd-repart, systemd-tmpfiles, systemd-sysusers, journalctl)
176 * seccomp: by default mask x32 ABI system wide on x86-64. it's on its way out
178 * seccomp: don't install filters for ABIs that are masked anyway for the
181 * seccomp: maybe merge all filters we install into one with that libseccomp API that allows merging.
183 * credentials system:
184 - maybe add AcquireCredential= for querying a cred via ask-password
185 - maybe try to acquire creds via keyring?
186 - maybe try to pass creds via keyring?
187 - maybe optionally pass creds via memfd
188 - maybe add support for decrypting creds via TPM
189 - maybe add support for decrypting/importing creds via pkcs11
190 - make systemd-cryptsetup acquire pw via creds logic
191 - make PAMName= acquire pw via creds logic
192 - make macsec/wireguard code in networkd read key via creds logic
193 - make gatwayd/remote read key via creds logic
194 - add sd_notify() command for flushing out creds not needed anymore
196 * homed: during login resize fs automatically towards size goal. Specifically,
197 resize to diskSize if possible, but leave a certain amount (configured by a
198 new value diskLeaveFreeSize) of space free on the backing fs.
200 * homed: permit multiple user record signing keys to be used locally, and pick
201 the right one for signing records automatically depending on a pre-existing
204 * homed: add a way to "adopt" a home directory, i.e. strip foreign signatures
205 and insert a local signature instead.
207 * homed: as an extension to the directory+subvolume backend: if located on
208 especially marked fs, then sync down password into LUKS header of that fs,
209 and always verify passwords against it too. Bootstrapping is a problem
210 though: if no one is logged in (or no other user even exists yet), how do you
211 unlock the volume in order to create the first user and add the first pw.
213 * homed: support new FS_IOC_ADD_ENCRYPTION_KEY ioctl for setting up fscrypt
215 * homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
218 * busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
221 * when systemd-nspawn and suchlike dissect an OS image, and there are multiple
222 root partitions, do an strverscmp() on the partition label and boot
223 first. That is inspired how sd-boot figures out which kernel to boot, and
224 thus allows defining OS images which can be A/B updated and we default to the
225 newest version automatically, both in nspawn and in sd-boot
227 * systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
231 - teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation
232 - teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host
233 - make it operate on loopback files, dissecting enough to find ESP to operate on
235 * Maybe add a separate GPT partition type to the discoverable partition spec
236 for "hibernate" partitions, that are exactly like swap partitions but only
237 activated right before hibernation and thus never used for regular swapping.
239 * by default, in systemd --user service bump the OOMAdjust to 100, as privs
240 allow so that systemd survives
242 * cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a
243 "base64:" prefix. Useful in particular for pkcs11 mode.
245 * cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use
246 systemd-makefs.service instead.
248 * socket units: allow creating a udev monitor socket with ListenDevices= or so,
249 with matches, then activate app through that passing socket over
251 * unify on openssl (as soon as OpenSSL 3.0 is out, and the Debian license
253 - port sd_id128_get_machine_app_specific() over from khash
254 - port resolved over from libgcrypt (DNSSEC code)
255 - port journald + fsprg over from libgcrypt
256 - port importd over from libgcrypt
257 - when that's done: kill khash.c
258 - when that's done: kill gnutls support in resolved
260 * when we resize disks (homed?) always round up to 4K sectors, not 512K
262 * add growvol and makevol options for /etc/crypttab, similar to
263 x-systemd.growfs and x-systemd-makefs.
265 * systemd-repart: by default generate minimized partition tables (i.e. tables
266 that only cover the space actually used, excluding any free space at the
267 end), in order to maximize dd'ability. Requires libfdisk work, see
268 https://github.com/karelzak/util-linux/issues/907
270 * systemd-repart: MBR partition table support. Care needs to be taken regarding
271 Type=, so that partition definitions can sanely apply to both the GPT and the
272 MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types
273 for the two partition types explicitly. And provide an internal mapping so
274 that "Type=linux-generic" maps to the right types for both partition tables
277 * systemd-repart: allow sizing partitions as factor of available RAM, so that
278 we can reasonably size swap partitions for hibernation.
280 * systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
282 * systemd-repart: allow boolean option that ensures that if existing partition
283 doesn't exist within the configured size bounds the whole command fails. This
284 is useful to implement ESP vs. XBOOTLDR schemes in installers: have one set
285 of repart files for the case where ESP is large enough and one where it isn't
286 and XBOOTLDR is added in instead. Then apply the former first, and if it
287 fails to apply use the latter.
289 * systemd-repart: add per-partition option to never reuse existing partition
290 and always create anew even if matching partition already exists.
292 * systemd-repart: add per-partition option to fail if partition already exist,
293 i.e. is not added new. Similar, add option to fail if partition does not exist yet.
295 * systemd-repart: allow disabling growing of specific partitions, or making
296 them (think ESP: we don't ever want to grow it, since we cannot resize vfat)
298 * systemd-repart: make it a static checker during early boot for existence and
299 absence of other partitions for trusted boot environments
301 * userdb: allow username prefix searches in varlink API, allow realname and
302 realname substr searches in varlink API
304 * userdb: allow uid/gid range checks
306 * userdb: allow existence checks
308 * pid1: activation by journal search expression
310 * when switching root from initrd to host, set the machine_id env var so that
311 if the host has no machine ID set yet we continue to use the random one the
314 * sd-event: add native support for P_ALL waitid() watching, then move PID 1 to
315 it for reaping assigned but unknown children. This needs to some special care
316 to operate somewhat sensibly in light of priorities: P_ALL will return
317 arbitrary processes, regardless of the priority we want to watch them with,
318 hence on each event loop iteration check all processes which we shall watch
319 with higher prio explicitly, and then watch the entire rest with P_ALL.
321 * tweak sd-event's child watching: keep a prioq of children to watch and use
322 waitid() only on the children with the highest priority until one is waitable
323 and ignore all lower-prio ones from that point on
325 * maybe introduce xattrs that can be set on the root dir of the root fs
326 partition that declare the volatility mode to use the image in. Previously I
327 thought marking this via GPT partition flags but that's not ideal since
328 that's outside of the LUKS encryption/verity verification, and we probably
329 shouldn't operate in a volatile mode unless we got told so from a trusted
332 * figure out automatic partition discovery when combining writable root dir
335 * coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
336 may be used to mark a whole binary as non-coredumpable. Would fix:
337 https://bugs.freedesktop.org/show_bug.cgi?id=69447
339 * teach parse_timestamp() timezones like the calendar spec already knows it
341 * beef up hibernation to optionally do swapon/swapoff immediately before/after
344 * beef up s2h to implement a battery watch loop: instead of entering
345 hibernation unconditionally after coming back from resume make a decision
346 based on the battery load level: if battery level is above a specific
347 threshold, go to suspend again, only hibernate if below it. This means we'd
348 stick to suspend usually, but fall back to hibernation only when battery runs
349 empty (well, subject to our sampling interval). Related to this, check if we
350 can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
351 i.e. see if it can wake up machines from suspend, so that we could resume
352 automatically when the system is low on power and move automatically to
353 hibernation mode. (see
354 https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
356 https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
359 * add an explicit "vertical" mode to format-table, so that "systemctl
360 status"-like outputs (i.e. with a series of field names left and values
361 right) become genuine first class citizens, and we gain automatic, sane JSON
364 * We should probably replace /var/log/README, /etc/rc.d/README with symlinks
365 that are linked to these places instead of copied. After all they are
366 constant vendor data.
368 * maybe add kernel cmdline params: to force random seed crediting
370 * nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
371 so that we make cgroup agent logic safe
373 * nspawn/machined: add API to invoke binary in container, then use that as
374 fallback in "machinectl shell"
376 * logind: rework pam_logind to also do a bus call in case of invocation from
377 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
378 behaviour selectable via pam module option.
381 - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth
382 - rollback when resize fails mid-operation
383 - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid)
385 - shrink fs on logout?
386 - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device.
387 - create on activate?
388 - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls?
389 - communicate clearly when usb stick is safe to remove. probably involves
390 beefing up logind to make pam session close hook synchronous and wait until
391 systemd --user is shut down.
392 - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service
393 - maybe make automatic, read-only, time-based reflink-copies of LUKS disk
394 images (and btrfs snapshots of subvolumes) (think: time machine)
395 - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory)
396 - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work
397 - fingerprint authentication, pattern authentication, …
398 - make sure "classic" user records can also be managed by homed
399 - make size of $XDG_RUNTIME_DIR configurable in user record
400 - query password from kernel keyring first
401 - update even if record is "absent"
402 - add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends
403 - move acct mgmt stuff from pam_systemd_home to pam_systemd?
404 - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for
405 - make slice for users configurable (requires logind rework)
406 - logind: populate auto-login list bus property from PKCS#11 token
407 - when determining state of a LUKS home directory, check DM suspended sysfs file
408 - introduce API for "making room", that grows/shrinks home directory
409 according to elastic parameters, discards blocks, and removes additional snapshots. Call it
410 either from UI when disk space gets low
412 * introduce a new per-process uuid, similar to the boot id, the machine id, the
413 invocation id, that is derived from process creds, specifically a hashed
414 combination of AT_RANDOM + getpid() + the starttime from
415 /proc/self/status. Then add these ids implicitly when logging. Deriving this
416 uuid from these three things has the benefit that it can be derived easily
417 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
420 * let's not GC a unit while its ratelimits are still pending
422 * when killing due to service watchdog timeout maybe detect whether target
423 process is under ptracing and then log loudly and continue instead.
425 * introduce a new group to own TPM devices
427 * make rfkill uaccess controllable by default, i.e. steal rule from
428 gnome-bluetooth and friends
430 * tweak journald context caching. In addition to caching per-process attributes
431 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
432 keyed by cgroup path, and guarded by ctime changes. This should provide us
433 with a nice speed-up on services that have many processes running in the same
436 * make MAINPID= message reception checks even stricter: if service uses User=,
437 then check sending UID and ignore message if it doesn't match the user or
440 * maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
443 * when importing an fs tree with machined, optionally apply userns-rec-chown
445 * when importing an fs tree with machined, complain if image is not an OS
447 * Maybe introduce a helper safe_exec() or so, which is to execve() which
448 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
449 to 1K implicitly, unless explicitly opted-out.
451 * rework seccomp/nnp logic that even if User= is used in combination with
452 a seccomp option we don't have to set NNP. For that, change uid first whil
453 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
455 * add a concept for automatically loading per-unit secrets off disk and
456 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
457 ConfigurationDirectory=.
459 * when no locale is configured, default to UEFI's PlatformLang variable
461 * bootctl,sd-boot: actually honour the "architecture" key
463 * add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
464 usefaultd() and make systemd-analyze check for it.
466 * paranoia: whenever we process passwords, call mlock() on the memory
467 first. i.e. look for all places we use free_and_erasep() and
468 augment them with mlock(). Also use MADV_DONTDUMP.
470 * Move RestrictAddressFamily= to the new cgroup create socket
472 * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
475 * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
476 log.c and sd-journal-send
478 * optionally: turn on cgroup delegation for per-session scope units
480 * introduce per-unit (i.e. per-slice, per-service) journal log size limits.
482 * sd-boot: automatically load EFI modules from some drop-in dir, so that people
483 can add in file system drivers and such
485 * sd-boot: optionally, show boot menu when previous default boot item has
486 non-zero "tries done" count
488 * introduce an option (or replacement) for "systemctl show" that outputs all
489 properties as JSON, similar to busctl's new JSON output. In contrast to that
490 it should skip the variant type string though.
492 * augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
493 contains some identifier for the project, which allows us to include
494 clickable links to source files generating these log messages. The identifier
495 could be some abberviated URL prefix or so (taking inspiration from Go
496 imports). For example, for systemd we could use
497 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
498 sufficient to build a link by prefixing "http://" and suffixing the
501 * Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
502 make clickable links from log messages carrying a MESSAGE_ID, that lead to
503 some explanatory text online.
505 * maybe extend .path units to expose fanotify() per-mount change events
507 * Add a "systemctl list-units --by-slice" mode or so, which rearranges the
508 output of "systemctl list-units" slightly by showing the tree structure of
509 the slices, and the units attached to them.
511 * the a-posteriori stopping of units bound to units that disappeared logic
512 should be reworked: there should be a queue of units, and we should only
513 enqueue stop jobs from a defer event that processes queue instead of
514 right-away when we find a unit that is bound to one that doesn't exist
515 anymore. (similar to how the stop-unneeded queue has been reworked the same
518 * nspawn: make nspawn suitable for shell pipelines: instead of triggering a
519 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
520 for hangup or ^D before passing on the EOF.
522 * When reloading configuration PID 1 should reset all its properties to the
523 original defaults before calling parse_config()
525 * nspawn: greater control over selinux label?
527 * hibernate/s2h: make this robust and safe to enable in Fedora by default.
530 1. add resume_offset support to the resume code (i.e. support swap files
532 2. check if swap is on weird storage and refuse if so
533 3. add auto-detection of hibernation images
535 * cgroups: use inotify to get notified when somebody else modifies cgroups
536 owned by us, then log a friendly warning.
538 * beef up log.c with support for stripping ANSI sequences from strings, so that
539 it is OK to include them in log strings. This would be particularly useful so
540 that our log messages could contain clickable links for example for unit
541 files and suchlike we operate on.
543 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
545 * add attach --enable and attach --now (for attach+enable+start)
547 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
548 selected user is resolvable in the service even if it ships its own /etc/passwd)
550 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
551 other doesn't. What a disaster. Probably to exclude it. Also
552 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
555 * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
556 usually IN_ATTRIB is the right way to watch deleted files, as the former only
557 fires when a file is actually removed from disk, i.e. the link count drops to
558 zero and is not open anymore, while the latter happens when a file is
559 unlinked from any dir.
561 * port systemctl, busctl, … over to format-table.[ch]'s table formatters
563 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
565 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
567 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
568 files and directories that are left writable for a unit, and which are
569 removed after the unit goes down again. A bit like --ephemeral for
570 systemd-nspawn but for system services. If used together with RootImage= this
571 should reflink the image file itself.
573 Related: add Ephemeral=<path1> <path2> … which would allow marking
574 specific paths only like this.
576 * add CopyFile= or so as unit file setting that may be used to copy files or
577 directory trees from the host to the services RootImage= and RootDirectory=
578 environment. Which we can use for /etc/machine-id and in particular
579 /etc/resolv.conf. Should be smart and do something useful on read-only
580 images, for example fall back to read-only bind mounting the file instead.
582 * show invocation ID in systemd-run output
584 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
586 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
587 and so on, which would mean we could report errors and such.
589 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
592 * introduce DefaultSlice= or so in system.conf that allows changing where we
593 place our units by default, i.e. change system.slice to something
594 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
595 be moved somewhere else too. Finally machined and logind should get similar
596 options so that it is possible to move user session scopes and machines to a
597 different slice too by default. Usecase: people who want to put resources on
598 the entire system, with the exception of one specific service. See:
599 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
601 * maybe rework get_user_creds() to query the user database if $SHELL is used
602 for root, but only then.
604 * be stricter with fds we receive for the fdstore: close them asynchronously
606 * calenderspec: add support for week numbers and day numbers within a
607 year. This would allow us to define "bi-weekly" triggers safely.
609 * sd-bus: add vtable flag, that may be used to request client creds implicitly
610 and asynchronously before dispatching the operation
612 * sd-bus: parse addresses given in sd_bus_set_addresses immediately and not
613 only when used. Add unit tests.
615 * make use of ethtool veth peer info in machined, for automatically finding out
616 host-side interface pointing to the container.
618 * add some special mode to LogsDirectory=/StateDirectory=… that allows
619 declaring these directories without necessarily pulling in deps for them, or
620 creating them when starting up. That way, we could declare that
621 systemd-journald writes to /var/log/journal, which could be useful when we
622 doing disk usage calculations and so on.
624 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
626 * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
628 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
629 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
630 as the unit is running or has a job queued.
632 * support projid-based quota in machinectl for containers
634 * add a way to lock down cgroup migration: a boolean, which when set for a unit
635 makes sure the processes in it can never migrate out of it
637 * blog about fd store and restartable services
639 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
641 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
642 magic meaning and is no longer upgraded to something else if set explicitly.
644 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
645 make it lose its identity, i.e. be anonymous. For this we'd have to patch
646 through the whole tree to make all code deal with the case where no machine
649 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
650 suitable for processing with rrdtool. Add bus API to access this data, and
651 possibly implement a CPULoad property based on it.
653 * beef up pam_systemd to take unit file settings such as cgroups properties as
656 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
657 the quota of the user indicated in User= via unit file settings, like the
658 other resource management concepts. Would mix nicely with DynamicUser=1. Or
659 alternatively, do this with projids, so that we can also cover services
660 running as root. Quota should probably cover all the special dirs such as
661 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
662 is set, plus the whole disk space any image configured with RootImage=.
664 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
665 disks to see if the UID is already in use.
667 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
668 for all units. It should be both a way to pin units into memory as well as a
669 wait to retrieve their exit data.
671 * expose IO accounting data on the bus, show it in systemd-run --wait and log
672 about it in the resource log message
674 * show whether a service has out-of-date configuration in "systemctl status" by
675 using mtime data of ConfigurationDirectory=.
677 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
678 creates a static, persistent user rather than a dynamic, transient user. We
679 can leverage code from sysusers.d for this.
681 * add some optional flag to ReadWritePaths= and friends, that has the effect
682 that we create the dir in question when the service is started. Example:
684 ReadWritePaths=:/var/lib/foobar
686 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
687 the sd-journal logging socket, and, if the timeout is set to 0, sets
688 O_NONBLOCK on it. That way people can control if and when to block for
691 * hostnamed: populate form factor data from a new hwdb database, so that old
692 yogas can be recognized as "convertible" too, even if they predate the DMI
693 "convertible" form factor
695 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
696 the service cgroup, which is supposed to monitor the service, and when it
697 exits the service is considered failed by its monitor.
699 * track the per-service PAM process properly (i.e. as an additional control
700 process), so that it may be queried on the bus and everything.
702 * add a new "debug" job mode, that is propagated to unit_start() and for
703 services results in two things: we raise SIGSTOP right before invoking
704 execve() and turn off watchdog support. Then, use that to implement
705 "systemd-gdb" for attaching to the start-up of any system service in its
708 * gpt-auto logic: related to the above, maybe support a "secondary" root
709 partition, that is mounted to / and is writable, and where the actual root's
710 /usr is mounted into.
712 * 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
714 * drop nss-myhostname in favour of nss-resolve?
716 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
717 then use that for the setting used in user@.service. It should be understood
718 relative to the configured default value.
720 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
722 * enable LockMLOCK to take a percentage value relative to physical memory
724 * Permit masking specific netlink APIs with RestrictAddressFamily=
726 * nspawn: support that /proc, /sys/, /dev are pre-mounted
728 * define gpt header bits to select volatility mode
730 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
732 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
734 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
736 * ProtectKeyRing= to take keyring calls away
738 * RemoveKeyRing= to remove all keyring entries of the specified user
740 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
741 on PID 1 with the relevant signals, and makes relevant files in /sys and
742 /proc (such as the sysrq stuff) unavailable
744 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
746 * journalctl: make sure -f ends when the container indicated by -M terminates
748 * mount: automatically search for "main" partition of an image has multiple
751 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
752 find a way to map the User=/Group= of the service to the right name. This way
753 a user/group for a service only has to exist on the host for the right
756 * add bus API for creating unit files in /etc, reusing the code for transient units
758 * add bus API to remove unit files from /etc
760 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
762 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
763 kernel doesn't support linkat() that replaces existing files, currently)
765 * transient units: don't bother with actually setting unit properties, we
766 reload the unit file anyway
768 * journald: sigbus API via a signal-handler safe function that people may call
769 from the SIGBUS handler
771 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
773 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
774 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
776 * cache sd_event_now() result from before the first iteration...
778 * PID1: find a way how we can reload unit file configuration for
779 specific units only, without reloading the whole of systemd
781 * add an explicit parser for LimitRTPRIO= that verifies
782 the specified range and generates sane error messages for incorrect
785 * when we detect that there are waiting jobs but no running jobs, do something
787 * push CPUAffinity= also into the "cpuset" cgroup controller
789 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
791 * there's probably something wrong with having user mounts below /sys,
792 as we have for debugfs. for example, src/core/mount.c handles mounts
793 prefixed with /sys generally special.
794 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
796 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
798 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
800 * add a job mode that will fail if a transaction would mean stopping
801 running units. Use this in timedated to manage the NTP service
803 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
805 * The udev blkid built-in should expose a property that reflects
806 whether media was sensed in USB CF/SD card readers. This should then
807 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
808 picked up by systemd unless they contain a medium. This would mirror
809 the behaviour we already have for CD drives.
811 * networkd/udev: implement SR_IOV configuration in .link files:
812 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
814 * hostnamectl: show root image uuid
816 * Find a solution for SMACK capabilities stuff:
817 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
819 * "systemctl preset-all" should probably order the unit files it
820 operates on lexicographically before starting to work, in order to
821 ensure deterministic behaviour if two unit files conflict (like DMs
824 * synchronize console access with BSD locks:
825 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
827 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
828 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
830 * figure out when we can use the coarse timers
832 * add "systemctl start -v foobar.service" that shows logs of a service
833 while the start command runs. This is non-trivial to do without
834 races though, since we should flush out all journal messages before
835 returning from the "systemctl stop".
837 * 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
839 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
841 * maybe allow timer units with an empty Units= setting, so that they
842 can be used for resuming the system but nothing else.
844 * what to do about udev db binary stability for apps? (raw access is not an option)
846 * systemctl: if some operation fails, show log output?
848 * exponential backoff in timesyncd when we cannot reach a server
850 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
852 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
854 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
855 (throughout the codebase, not only PID1)
859 - service registration
860 - service/domain/types browsing
862 - DNS-SD service registration from socket units
863 - resolved should optionally register additional per-interface LLMNR
864 names, so that for the container case we can establish the same name
865 (maybe "host") for referencing the server, everywhere.
866 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
867 - hook up resolved with machined-based address resolution
869 * refcounting in sd-resolve is borked
871 * Add a new verb "systemctl top"
873 * add new gpt type for btrfs volumes
875 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
877 * a way for container managers to turn off getty starting via $container_headless= or so...
879 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
881 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
882 they run added to the initial transaction and thus confuse Type=idle.
884 * add bus api to query unit file's X fields.
886 * gpt-auto-generator:
887 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
888 - Make /home automount rather than mount?
890 * add generator that pulls in systemd-network from containers when
891 CAP_NET_ADMIN is set, more than the loopback device is defined, even
892 when it is otherwise off
894 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
896 * implement Distribute= in socket units to allow running multiple
897 service instances processing the listening socket, and open this up
901 - implement per-slice CPUFairScheduling=1 switch
902 - introduce high-level settings for RT budget, swappiness
903 - how to reset dynamically changed unit cgroup attributes sanely?
904 - when reloading configuration, apply new cgroup configuration
905 - when recursively showing the cgroup hierarchy, optionally also show
906 the hierarchies of child processes
909 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
911 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
913 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
915 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
917 * 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
919 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
921 * If we try to find a unit via a dangling symlink, generate a clean
922 error. Currently, we just ignore it and read the unit from the search
925 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
927 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
929 * load .d/*.conf dropins for device units
933 - GetAllProperties() on a non-existing object does not result in a failure currently
934 - port to sd-resolve for connecting to TCP dbus servers
935 - 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
936 - see if we can drop more message validation on the sending side
937 - add API to clone sd_bus_message objects
938 - longer term: priority inheritance
940 - NameLost/NameAcquired obsolete
943 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
946 - allow multiple signal handlers per signal?
947 - document chaining of signal handler for SIGCHLD and child handlers
948 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
949 - maybe support iouring as backend, so that we allow hooking read and write
950 operations instead of IO ready events into event loops. See considerations
952 http://blog.vmsplice.net/2020/07/rethinking-event-loop-integration-for.html
954 * investigate endianness issues of UUID vs. GUID
956 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
957 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
959 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
961 * add a pam module that on password changes updates any LUKS slot where the password matches
964 - add unit tests for config_parse_device_allow()
966 * seems that when we follow symlinks to units we prefer the symlink
967 destination path over /etc and /usr. We should not do that. Instead
968 /etc should always override /run+/usr and also any symlink
971 * when isolating, try to figure out a way how we implicitly can order
972 all units we stop before the isolating unit...
974 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
976 * Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add
977 ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at
978 https://github.com/systemd/systemd/pull/15109#issuecomment-607740136.
980 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
981 that the boot loader should be installed to the ESP. Define a way
982 how an installer can figure out whether a BLS compliant boot loader
985 * think about requeuing jobs when daemon-reload is issued? usecase:
986 the initrd issues a reload after fstab from the host is accessible
987 and we might want to requeue the mounts local-fs acquired through
990 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
992 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
994 * shutdown logging: store to EFI var, and store to USB stick?
996 * merge unit_kill_common() and unit_kill_context()
999 - honor language efi variables for default language selection (if there are any?)
1000 - honor timezone efi variables for default timezone selection (if there are any?)
1001 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
1003 - recognize the case when not booted on EFI
1005 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
1007 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
1009 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
1012 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
1013 - logind: wakelock/opportunistic suspend support
1014 - Add pretty name for seats in logind
1015 - logind: allow showing logout dialog from system?
1016 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
1017 - if pam_systemd is invoked by su from a process that is outside of a
1018 any session we should probably just become a NOP, since that's
1019 usually not a real user session but just some system code that just
1021 - logind: make the Suspend()/Hibernate() bus calls wait for the for
1022 the job to be completed. before returning, so that clients can wait
1023 for "systemctl suspend" to finish to know when the suspending is
1025 - logind: when the power button is pressed short, just popup a
1026 logout dialog. If it is pressed for 1s, do the usual
1027 shutdown. Inspiration are Macs here.
1028 - expose "Locked" property on logind session objects
1029 - maybe allow configuration of the StopTimeout for session scopes
1030 - rename session scope so that it includes the UID. THat way
1031 the session scope can be arranged freely in slices and we don't have
1032 make assumptions about their slice anymore.
1033 - follow PropertiesChanged state more closely, to deal with quick logouts and
1035 - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set
1038 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
1039 - journald: also get thread ID from client, plus thread name
1040 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
1041 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
1042 - fall back to /dev/log based logging in libsystemd-journal, if we cannot log natively?
1043 - declare the local journal protocol stable in the wiki interface chart
1044 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
1045 - journald: when dropping msgs due to ratelimit make sure to write
1046 "dropped %u messages" not only when we are about to print the next
1047 message that works, but already after a short timeout
1048 - check if we can make journalctl by default use --follow mode inside of less if called without args?
1049 - maybe add API to send pairs of iovecs via sd_journal_send
1050 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
1051 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
1052 and !FOOBAR for events without FOOBAR.
1053 - journal: store timestamp of journal_file_set_offline() in the header,
1054 so it is possible to display when the file was last synced.
1055 - 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.
1056 - journal: find a way to allow dropping history early, based on priority, other rules
1057 - journal: When used on NFS, check payload hashes
1058 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
1059 - refuse taking lower-case variable names in sd_journal_send() and friends.
1060 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
1061 - journal: deal nicely with byte-by-byte copied files, especially regards header
1062 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
1063 - Replace utmp, wtmp, btmp, and lastlog completely with journal
1064 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
1065 - when a kernel driver logs in a tight loop, we should ratelimit that too.
1066 - journald: optionally, log debug messages to /run but everything else to /var
1067 - journald: when we drop syslog messages because the syslog socket is
1068 full, make sure to write how many messages are lost as first thing
1069 to syslog when it works again.
1070 - journald: allow per-priority and per-service retention times when rotating/vacuuming
1071 - journald: make use of uid-range.h to managed uid ranges to split
1073 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
1074 - improve journalctl performance by loading journal files
1075 lazily. Encode just enough information in the file name, so that we
1076 do not have to open it to know that it is not interesting for us, for
1077 the most common operations.
1078 - man: document that corrupted journal files is nothing to act on
1079 - rework journald sigbus stuff to use mutex
1080 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
1081 services that run under their own user ids, and use User= (but only
1082 in a world where userns is ubiquitous since otherwise we cannot
1083 invoke those daemons on the host AND in a container anymore). Also,
1084 if LimitNPROC= is used without User= we should warn and refuse
1086 - journalctl --verify: don't show files that are currently being
1087 written to as FAIL, but instead show that their are being written to.
1088 - add journalctl -H that talks via ssh to a remote peer and passes through
1090 - add a version of --merge which also merges /var/log/journal/remote
1091 - journalctl: -m should access container journals directly by enumerating
1092 them via machined, and also watch containers coming and going.
1093 Benefit: nspawn --ephemeral would start working nicely with the journal.
1094 - assign MESSAGE_ID to log messages about failed services
1095 - check if loop in decompress_blob_xz() is necessary
1097 * add a test if all entries in the catalog are properly formatted.
1098 (Adding dashes in a catalog entry currently results in the catalog entry
1099 being silently skipped. journalctl --update-catalog must warn about this,
1100 and we should also have a unit test to check that all our message are OK.)
1103 - document that deps in [Unit] sections ignore Alias= fields in
1104 [Install] units of other units, unless those units are disabled
1105 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
1106 - document that service reload may be implemented as service reexec
1107 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
1108 - document systemd-journal-flush.service properly
1109 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
1110 - man: document the very specific env the shutdown drop-in tools live in
1111 - man: add more examples to man pages,
1112 - in particular an example how to do the equivalent of switching runlevels
1113 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
1114 - document root=gpt-auto properly
1117 - add systemctl switch to dump transaction without executing it
1118 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
1119 - "systemctl disable" on a static unit prints no message and does
1120 nothing. "systemctl enable" does nothing, and gives a bad message
1121 about it. Should fix both to print nice actionable messages.
1122 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
1123 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
1124 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
1125 - systemctl: "Journal has been rotated since unit was started." message is misleading
1126 - systemctl status output should include list of triggering units and their status
1129 - "systemctl mask" should find all names by which a unit is accessible
1130 (i.e. by scanning for symlinks to it) and link them all to /dev/null
1133 - timer units should get the ability to trigger when:
1135 - Modulate timer frequency based on battery state
1137 * add libsystemd-password or so to query passwords during boot using the password agent logic
1139 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
1141 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
1143 * make repeated alt-ctrl-del presses printing a dump
1145 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
1147 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
1150 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
1151 with seccomp. That should provide us with a useful log buffer that
1152 systemd can log to during early boot, and disconnect container logs
1153 from the kernel's logs.
1154 - as soon as networkd has a bus interface, hook up --network-interface=,
1155 --network-bridge= with networkd, to trigger netdev creation should an
1156 interface be missing
1157 - a nice way to boot up without machine id set, so that it is set at boot
1158 automatically for supporting --ephemeral. Maybe hash the host machine id
1159 together with the machine name to generate the machine id for the container
1160 - fix logic always print a final newline on output.
1161 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
1162 - should optionally support receiving WATCHDOG=1 messages from its payload
1164 - optionally automatically add FORWARD rules to iptables whenever nspawn is
1165 running, remove them when shut down.
1168 - add an API so that libvirt-lxc can inform us about network interfaces being
1169 removed or added to an existing machine
1170 - "machinectl migrate" or similar to copy a container from or to a
1171 difference host, via ssh
1172 - introduce systemd-nspawn-ephemeral@.service, and hook it into
1173 "machinectl start" with a new --ephemeral switch
1174 - "machinectl status" should also show internal logs of the container in
1176 - "machinectl history"
1178 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
1179 shell in it, and marks it read-only after use
1182 - cryptsetup-generator: allow specification of passwords in crypttab itself
1183 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
1185 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
1186 https://bugs.freedesktop.org/show_bug.cgi?id=54712
1188 * add a dependency on standard-conf.xml and other included files to man pages
1190 * MountFlags=shared acts as MountFlags=slave right now.
1192 * properly handle loop back mounts via fstab, especially regards to fsck/passno
1194 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
1199 - add trigger --subsystem-match=usb/usb_device device
1200 - reimport udev db after MOVE events for devices without dev_t
1202 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
1204 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
1207 - save coredump in Windows/Mozilla minidump format
1208 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
1210 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
1212 * be able to specify a forced restart of service A where service B depends on, in case B
1213 needs to be auto-respawned?
1216 - apply "x" on "D" too (see patch from William Douglas)
1217 - instead of ignoring unknown fields, reject them.
1218 - creating new directories/subvolumes/fifos/device nodes
1219 should not follow symlinks. None of the other adjustment or creation
1220 calls follow symlinks.
1222 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
1224 * verify that the AF_UNIX sockets of a service in the fs still exist
1225 when we start a service in order to avoid confusion when a user
1226 assumes starting a service is enough to make it accessible
1228 * Make it possible to set the keymap independently from the font on
1229 the kernel cmdline. Right now setting one resets also the other.
1231 * and a dbus call to generate target from current state
1233 * write blog stories about:
1234 - hwdb: what belongs into it, lsusb
1235 - enabling dbus services
1236 - how to make changes to sysctl and sysfs attributes
1238 - how to pass throw-away units to systemd, or dynamically change properties of existing units
1239 - testing with Harald's awesome test kit
1241 - how to develop against journal browsing APIs
1242 - the journal HTTP iface
1243 - non-cgroup resource management
1244 - dynamic resource management with cgroups
1245 - refreshed, longer missions statement
1246 - calendar time events
1247 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
1248 - how to create your own target
1249 - instantiated apache, dovecot and so on
1250 - hooking a script into various stages of shutdown/rearly booot
1252 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
1254 * dot output for --test showing the 'initial transaction'
1257 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
1258 log both units as UNIT=, so that journalctl -u triggers on both.
1259 - generate better errors when people try to set transient properties
1260 that are not supported...
1261 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
1262 - maybe introduce WantsMountsFor=? Usecase:
1263 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
1264 - recreate systemd's D-Bus private socket file on SIGUSR2
1265 - move PAM code into its own binary
1266 - when we automatically restart a service, ensure we restart its rdeps, too.
1267 - hide PAM options in fragment parser when compile time disabled
1268 - Support --test based on current system state
1269 - 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().
1270 - after deserializing sockets in socket.c we should reapply sockopts and things
1271 - drop PID 1 reloading, only do reexecing (difficult: Reload()
1272 currently is properly synchronous, Reexec() is weird, because we
1273 cannot delay the response properly until we are back, so instead of
1274 being properly synchronous we just keep open the fd and close it
1275 when done. That means clients do not get a successful method reply,
1276 but much rather a disconnect on success.
1277 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
1278 - when a bus name of a service disappears from the bus make sure to queue further activation requests
1281 - allow port=0 in .socket units
1282 - maybe introduce ExecRestartPre=
1283 - add ReloadSignal= for configuring a reload signal to use
1284 - implement Register= switch in .socket units to enable registration
1285 in Avahi, RPC and other socket registration services.
1286 - allow Type=simple with PIDFile=
1287 https://bugzilla.redhat.com/show_bug.cgi?id=723942
1288 - allow writing multiple conditions in unit files on one line
1289 - introduce Type=pid-file
1290 - introduce mix of BindTo and Requisite
1291 - add a concept of RemainAfterExit= to scope units
1292 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
1293 - add verification of [Install] section to systemd-analyze verify
1296 - Make sure ID_PATH is always exported and complete for
1297 network devices where possible, so we can safely rely
1301 - add support for more attribute types
1302 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
1305 - add more keys to [Route] and [Address] sections
1306 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
1307 - add reduced [Link] support to .network files
1308 - properly handle routerless dhcp leases
1309 - work with non-Ethernet devices
1310 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
1311 - the DHCP lease data (such as NTP/DNS) is still made available when
1312 a carrier is lost on a link. It should be removed instantly.
1313 - expose in the API the following bits:
1314 - option 15, domain name
1315 - option 12, hostname and/or option 81, fqdn
1316 - option 123, 144, geolocation
1317 - option 252, configure http proxy (PAC/wpad)
1318 - provide a way to define a per-network interface default metric value
1319 for all routes to it. possibly a second default for DHCP routes.
1320 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1321 support Name=foo*|bar*|baz ?
1322 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1323 - whenever uplink info changes, make DHCP server send out FORCERENEW
1325 * Figure out how to do unittests of networkd's state serialization
1328 - figure out how much we can increase Maximum Message Size
1331 - add functions to set previously stored IPv6 addresses on startup and get
1332 them at shutdown; store them in client->ia_na
1333 - write more test cases
1334 - implement reconfigure support, see 5.3., 15.11. and 22.20.
1335 - implement support for temporary adressess (IA_TA)
1336 - implement dhcpv6 authentication
1337 - investigate the usefulness of Confirm messages; i.e. are there any
1338 situations where the link changes without any loss in carrier detection
1340 - some servers don't do rapid commit without a filled in IA_NA, verify
1347 - natively watch for dbus-*.service symlinks (PENDING)
1348 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1350 * make cryptsetup lower --iter-time
1352 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1354 * /usr/bin/service should actually show the new command line
1356 * 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=
1358 * neither pkexec nor sudo initialize environ[] from the PAM environment?
1360 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1362 * register catalog database signature as file magic
1364 * zsh shell completion:
1365 - <command> <verb> -<TAB> should complete options, but currently does not
1366 - systemctl add-wants,add-requires
1368 * systemctl status should know about 'systemd-analyze calendar ... --iterations='
1369 * If timer has just OnInactiveSec=..., it should fire after a specified time
1370 after being started.
1374 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1376 * check for strerror(r) instead of strerror(-r)
1380 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1382 * use secure_getenv() instead of getenv() where appropriate
1384 * link up selected blog stories from man pages and unit files Documentation= fields
1385 String is not UTF-8 clean, ignoring assignment
