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 * export action of device object on sd-device, so that monitor becomes useful
25 * add root=tmpfs that mounts a tmpfs to /sysroot (to be used in combination
26 with usr=…, for a similar effect as systemd.volatile=yes but without the
27 "hide-out" effect). Also, add root=gpt-auto-late support or so, that is like
28 root=gpt-auto but initially mounts a tmpfs to /sysroot, and then revisits
29 later after systemd-repart ran. Usecase: let's ship images with only /usr
30 partition, then on first boot create the root partition. In this case we want
31 to read the repart data from /usr before the root partition exists. Add
32 usr=gpt-auto that automatically finds a /usr partition.
34 * change SwitchRoot() implementation in PID 1 to use pivot_root(".", "."), as
35 documented in the pivot_root(2) man page, so that we can drop the /oldroot
38 * special case some calls of chase_symlinks() to use openat2() internally, so
39 that the kernel does what we otherwise do.
41 * homed: keep an fd to the homedir open at all times, to keep the fs pinned
42 (autofs and such) while user is loged in.
44 * nss-systemd: also synthesize shadow records for users/groups
46 * make use of new glibc 2.32 APIs sigabbrev_np() and strerrorname_np().
48 * cryptsetup: if keyfile specified in crypttab is AF_UNIX socket, connect to it
49 and read from it (like we do elsewhere with READ_FULL_FILE_CONNECT_SOCKET)
51 * when main nspawn supervisor process gets suspended due to SIGSTOP/SIGTTOU or
52 so, freeze the payload too.
54 * repart: support setting up dm-integrity with HMAC
56 * add /etc/integritytab, to support dm-integrity setups. In particular those
57 with HMAC as hash function, so that we can have a protected /home without
58 encryption (leaving encryption to the individual dirs/homed).
60 * complement root=, rootflags=, rootfstype= with rootsubdir= which allows
61 mounting a subdir of the root fs as actual root. This can be used as
62 fstype-agnostic version of btrfs' rootflags=subvol=foobar.
64 * if /usr/bin/swapoff fails due to OOM, log a friendly explanatory message about it
66 * build short web pages out of each catalog entry, build them along with man
67 pages, and include hyperlinks to them in the journal output
69 * machined: add API to acquire UID range. add API to mount/dissect loopback
70 file. Both protected by PK. Then make nspawn use these APIs to run
71 unprivileged containers. i.e. push the truly privileged bits into machined,
72 so that the client side can remain entirely unprivileged, with SUID or
75 * journald: do journal file writing out-of-process, with one writer process per
76 client UID, so that synthetic hash table collisions can slow down a specific
77 user's journal stream down but not the others.
79 * add "throttling" to sd-event event sources: optionally, when we wake up too
80 often for one, let's turn it off entirely for a while. Use that for the
81 /proc/self/mountinfo logic.
83 * nspawn: support time namespaces
85 * systemd-firstboot: make sure to always use chase_symlinks() before
88 * add ConditionSecurity=tpm2
90 * Remove any support for booting without /usr pre-mounted in the initrd entirely.
91 Update INITRD_INTERFACE.md accordingly.
93 * pid1: Move to tracking of main pid/control pid of units per pidfd
95 * pid1: support new clone3() fork-into-cgroup feature
97 * pid1: also remove PID files of a service when the service starts, not just
100 * make us use dynamically fewer deps for containers in general purpose distros:
101 o turn into dlopen() deps:
104 - p11-kit-trust (always)
105 - kmod-libs (only when called from PID 1)
106 - libblkid (only in RootImage= handling in PID 1, but not elsewhere)
107 - libpam (only when called from PID 1)
108 - bzip2, xz, lz4 (always — gzip and zstd should probably stay static deps the way they are,
109 since they are so basic and our defaults)
110 o move into separate libsystemd-shared-iptables.so .so
111 - iptables-libs (only used by nspawn + networkd)
113 * seccomp: when SystemCallArchitectures=native is set then don't install any
114 other seccomp filters for any of the other archs, in order to reduce the
115 number of seccomp filters we install needlessly.
117 * seccomp: maybe use seccomp_merge() to merge our filters per-arch if we can.
118 Apparently kernel performance is much better with fewer larger seccomp
119 filters than with more smaller seccomp filters.
121 * systemd-path: add ESP and XBOOTLDR path. Add "private" runtime/state/cache dir enum,
122 mapping to $RUNTIME_DIRECTORY, $STATE_DIRECTORY and such
124 * All tools that support --root= should also learn --image= so that they can
125 operate on disk images directly. Specifically: bootctl, systemctl,
126 coredumpctl. (Already done: systemd-nspawn, systemd-firstboot,
127 systemd-repart, systemd-tmpfiles, systemd-sysusers, journalctl)
129 * seccomp: by default mask x32 ABI system wide on x86-64. it's on its way out
131 * seccomp: don't install filters for ABIs that are masked anyway for the
134 * seccomp: maybe merge all filters we install into one with that libseccomp API that allows merging.
136 * credentials system:
137 - maybe add AcquireCredential= for querying a cred via ask-password
138 - maybe try to acquire creds via keyring?
139 - maybe try to pass creds via keyring?
140 - maybe optionally pass creds via memfd
141 - maybe add support for decrypting creds via TPM
142 - maybe add support for decrypting/importing creds via pkcs11
143 - make systemd-cryptsetup acquire pw via creds logic
144 - make PAMName= acquire pw via creds logic
145 - make macsec/wireguard code in networkd read key via creds logic
146 - make gatwayd/remote read key via creds logic
147 - add sd_notify() command for flushing out creds not needed anymore
149 * homed: during login resize fs automatically towards size goal. Specifically,
150 resize to diskSize if possible, but leave a certain amount (configured by a
151 new value diskLeaveFreeSize) of space free on the backing fs.
153 * homed: permit multiple user record signing keys to be used locally, and pick
154 the right one for signing records automatically depending on a pre-existing
157 * homed: add a way to "adopt" a home directory, i.e. strip foreign signatures
158 and insert a local signature instead.
160 * homed: as an extension to the directory+subvolume backend: if located on
161 especially marked fs, then sync down password into LUKS header of that fs,
162 and always verify passwords against it too. Bootstrapping is a problem
163 though: if no one is logged in (or no other user even exists yet), how do you
164 unlock the volume in order to create the first user and add the first pw.
166 * homed: support new FS_IOC_ADD_ENCRYPTION_KEY ioctl for setting up fscrypt
168 * homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
171 * busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
174 * when systemd-nspawn and suchlike dissect an OS image, and there are multiple
175 root partitions, do an strverscmp() on the partition label and boot
176 first. That is inspired how sd-boot figures out which kernel to boot, and
177 thus allows defining OS images which can be A/B updated and we default to the
178 newest version automatically, both in nspawn and in sd-boot
180 * cryptsetup: support FIDO2 tokens for deriving keys (i.e. do what homed can do
181 also in plain cryptsetup)
183 * systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
187 - teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation
188 - teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host
189 - make it operate on loopback files, dissecting enough to find ESP to operate on
191 * Maybe add a separate GPT partition type to the discoverable partition spec
192 for "hibernate" partitions, that are exactly like swap partitions but only
193 activated right before hibernation and thus never used for regular swapping.
195 * by default, in systemd --user service bump the OOMAdjust to 100, as privs
196 allow so that systemd survives
198 * cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a
199 "base64:" prefix. Useful in particular for pkcs11 mode.
201 * cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use
202 systemd-makefs.service instead.
204 * socket units: allow creating a udev monitor socket with ListenDevices= or so,
205 with matches, then activate app through that passing socket over
207 * unify on openssl (as soon as OpenSSL 3.0 is out, and the Debian license
209 - port sd_id128_get_machine_app_specific() over from khash
210 - port resolved over from libgcrypt (DNSSEC code)
211 - port journald + fsprg over from libgcrypt
212 - port importd over from libgcrypt
213 - when that's done: kill khash.c
214 - when that's done: kill gnutls support in resolved
216 * when we resize disks (homed?) always round up to 4K sectors, not 512K
218 * add growvol and makevol options for /etc/crypttab, similar to
219 x-systemd.growfs and x-systemd-makefs.
221 * hook up the TPM to /etc/crypttab, with a new option that is similar to the
222 new PKCS#11 option in crypttab, and allows unlocking a LUKS volume via a key
223 unsealed from the TPM. Optionally, if TPM is not available fall back to
224 TPM-less mode, and set up linear DM mapping instead (inspired by kpartx), so
225 that the device paths stay the same, regardless if crypto is used or not.
227 * systemd-repart: by default generate minimized partition tables (i.e. tables
228 that only cover the space actually used, excluding any free space at the
229 end), in order to maximize dd'ability. Requires libfdisk work, see
230 https://github.com/karelzak/util-linux/issues/907
232 * systemd-repart: MBR partition table support. Care needs to be taken regarding
233 Type=, so that partition definitions can sanely apply to both the GPT and the
234 MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types
235 for the two partition types explicitly. And provide an internal mapping so
236 that "Type=linux-generic" maps to the right types for both partition tables
239 * systemd-repart: allow sizing partitions as factor of available RAM, so that
240 we can reasonably size swap partitions for hibernation.
242 * systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
244 * systemd-repart: allow boolean option that ensures that if existing partition
245 doesn't exist within the configured size bounds the whole command fails. This
246 is useful to implement ESP vs. XBOOTLDR schemes in installers: have one set
247 of repart files for the case where ESP is large enough and one where it isn't
248 and XBOOTLDR is added in instead. Then apply the former first, and if it
249 fails to apply use the latter.
251 * systemd-repart: add per-partition option to never reuse existing partition
252 and always create anew even if matching partition already exists.
254 * systemd-repart: add per-partition option to fail if partition already exist,
255 i.e. is not added new. Similar, add option to fail if partition does not exist yet.
257 * systemd-repart: allow disabling growing of specific partitions, or making
258 them (think ESP: we don't ever want to grow it, since we cannot resize vfat)
260 * systemd-repart: make it a static checker during early boot for existence and
261 absence of other partitions for trusted boot environments
263 * userdb: allow username prefix searches in varlink API, allow realname and
264 realname substr searches in varlink API
266 * userdb: allow uid/gid range checks
268 * userdb: allow existence checks
270 * pid1: activation by journal search expression
272 * when switching root from initrd to host, set the machine_id env var so that
273 if the host has no machine ID set yet we continue to use the random one the
276 * sd-event: add native support for P_ALL waitid() watching, then move PID 1 to
277 it fo reaping assigned but unknown children. This needs to some special care
278 to operate somewhat sensibly in light of priorities: P_ALL will return
279 arbitrary processes, regardless of the priority we want to watch them with,
280 hence on each event loop iteration check all processes which we shall watch
281 with higher prio explicitly, and then watch the entire rest with P_ALL.
283 * tweak sd-event's child watching: keep a prioq of children to watch and use
284 waitid() only on the children with the highest priority until one is waitable
285 and ignore all lower-prio ones from that point on
287 * maybe introduce xattrs that can be set on the root dir of the root fs
288 partition that declare the volatility mode to use the image in. Previously I
289 thought marking this via GPT partition flags but that's not ideal since
290 that's outside of the LUKS encryption/verity verification, and we probably
291 shouldn't operate in a volatile mode unless we got told so from a trusted
294 * figure out automatic partition discovery when combining writable root dir
297 * coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
298 may be used to mark a whole binary as non-coredumpable. Would fix:
299 https://bugs.freedesktop.org/show_bug.cgi?id=69447
301 * teach parse_timestamp() timezones like the calendar spec already knows it
303 * beef up hibernation to optionally do swapon/swapoff immediately before/after
306 * beef up s2h to implement a battery watch loop: instead of entering
307 hibernation unconditionally after coming back from resume make a decision
308 based on the battery load level: if battery level is above a specific
309 threshold, go to suspend again, only hibernate if below it. This means we'd
310 stick to suspend usually, but fall back to hibernation only when battery runs
311 empty (well, subject to our sampling interval). Related to this, check if we
312 can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
313 i.e. see if it can wake up machines from suspend, so that we could resume
314 automatically when the system is low on power and move automatically to
315 hibernation mode. (see
316 https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
318 https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
321 * add an explicit "vertical" mode to format-table, so that "systemctl
322 status"-like outputs (i.e. with a series of field names left and values
323 right) become genuine first class citizens, and we gain automatic, sane JSON
326 * We should probably replace /var/log/README, /etc/rc.d/README with symlinks
327 that are linked to these places instead of copied. After all they are
328 constant vendor data.
330 * maybe add kernel cmdline params: to force random seed crediting
332 * nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
333 so that we make cgroup agent logic safe
335 * nspawn/machined: add API to invoke binary in container, then use that as
336 fallback in "machinectl shell"
338 * logind: rework pam_logind to also do a bus call in case of invocation from
339 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
340 behaviour selectable via pam module option.
343 - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth
344 - rollback when resize fails mid-operation
345 - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid)
347 - shrink fs on logout?
348 - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device.
349 - create on activate?
350 - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls?
351 - communicate clearly when usb stick is safe to remove. probably involves
352 beefing up logind to make pam session close hook synchronous and wait until
353 systemd --user is shut down.
354 - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service
355 - maybe make automatic, read-only, time-based reflink-copies of LUKS disk
356 images (and btrfs snapshots of subvolumes) (think: time machine)
357 - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory)
358 - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work
359 - fingerprint authentication, pattern authentication, …
360 - make sure "classic" user records can also be managed by homed
361 - make size of $XDG_RUNTIME_DIR configurable in user record
362 - query password from kernel keyring first
363 - update even if record is "absent"
364 - add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends
365 - move acct mgmt stuff from pam_systemd_home to pam_systemd?
366 - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for
367 - make slice for users configurable (requires logind rework)
368 - logind: populate auto-login list bus property from PKCS#11 token
369 - when determining state of a LUKS home directory, check DM suspended sysfs file
370 - introduce API for "making room", that grows/shrinks home directory
371 according to elastic parameters, discards blocks, and removes additional snapshots. Call it
372 either from UI when disk space gets low
374 * introduce a new per-process uuid, similar to the boot id, the machine id, the
375 invocation id, that is derived from process creds, specifically a hashed
376 combination of AT_RANDOM + getpid() + the starttime from
377 /proc/self/status. Then add these ids implicitly when logging. Deriving this
378 uuid from these three things has the benefit that it can be derived easily
379 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
382 * let's not GC a unit while its ratelimits are still pending
384 * when killing due to service watchdog timeout maybe detect whether target
385 process is under ptracing and then log loudly and continue instead.
387 * introduce a new group to own TPM devices
389 * make rfkill uaccess controllable by default, i.e. steal rule from
390 gnome-bluetooth and friends
392 * tweak journald context caching. In addition to caching per-process attributes
393 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
394 keyed by cgroup path, and guarded by ctime changes. This should provide us
395 with a nice speed-up on services that have many processes running in the same
398 * make MAINPID= message reception checks even stricter: if service uses User=,
399 then check sending UID and ignore message if it doesn't match the user or
402 * maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
405 * when importing an fs tree with machined, optionally apply userns-rec-chown
407 * when importing an fs tree with machined, complain if image is not an OS
409 * Maybe introduce a helper safe_exec() or so, which is to execve() which
410 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
411 to 1K implicitly, unless explicitly opted-out.
413 * rework seccomp/nnp logic that even if User= is used in combination with
414 a seccomp option we don't have to set NNP. For that, change uid first whil
415 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
417 * add a concept for automatically loading per-unit secrets off disk and
418 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
419 ConfigurationDirectory=.
421 * when no locale is configured, default to UEFI's PlatformLang variable
423 * bootctl,sd-boot: actually honour the "architecture" key
425 * add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
426 usefaultd() and make systemd-analyze check for it.
428 * paranoia: whenever we process passwords, call mlock() on the memory
429 first. i.e. look for all places we use free_and_erasep() and
430 augment them with mlock(). Also use MADV_DONTDUMP.
432 * Move RestrictAddressFamily= to the new cgroup create socket
434 * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
437 * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
438 log.c and sd-journal-send
440 * optionally: turn on cgroup delegation for per-session scope units
442 * introduce per-unit (i.e. per-slice, per-service) journal log size limits.
444 * sd-boot: automatically load EFI modules from some drop-in dir, so that people
445 can add in file system drivers and such
447 * sd-boot: optionally, show boot menu when previous default boot item has
448 non-zero "tries done" count
450 * introduce an option (or replacement) for "systemctl show" that outputs all
451 properties as JSON, similar to busctl's new JSON output. In contrast to that
452 it should skip the variant type string though.
454 * augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
455 contains some identifier for the project, which allows us to include
456 clickable links to source files generating these log messages. The identifier
457 could be some abberviated URL prefix or so (taking inspiration from Go
458 imports). For example, for systemd we could use
459 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
460 sufficient to build a link by prefixing "http://" and suffixing the
463 * Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
464 make clickable links from log messages carrying a MESSAGE_ID, that lead to
465 some explanatory text online.
467 * maybe extend .path units to expose fanotify() per-mount change events
469 * Add a "systemctl list-units --by-slice" mode or so, which rearranges the
470 output of "systemctl list-units" slightly by showing the tree structure of
471 the slices, and the units attached to them.
473 * the a-posteriori stopping of units bound to units that disappeared logic
474 should be reworked: there should be a queue of units, and we should only
475 enqueue stop jobs from a defer event that processes queue instead of
476 right-away when we find a unit that is bound to one that doesn't exist
477 anymore. (similar to how the stop-unneeded queue has been reworked the same
480 * nspawn: make nspawn suitable for shell pipelines: instead of triggering a
481 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
482 for hangup or ^D before passing on the EOF.
484 * When reloading configuration PID 1 should reset all its properties to the
485 original defaults before calling parse_config()
487 * nspawn: greater control over selinux label?
489 * hibernate/s2h: make this robust and safe to enable in Fedora by default.
492 1. add resume_offset support to the resume code (i.e. support swap files
494 2. check if swap is on weird storage and refuse if so
495 3. add auto-detection of hibernation images
497 * cgroups: use inotify to get notified when somebody else modifies cgroups
498 owned by us, then log a friendly warning.
500 * beef up log.c with support for stripping ANSI sequences from strings, so that
501 it is OK to include them in log strings. This would be particularly useful so
502 that our log messages could contain clickable links for example for unit
503 files and suchlike we operate on.
505 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
507 * add attach --enable and attach --now (for attach+enable+start)
509 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
510 selected user is resolvable in the service even if it ships its own /etc/passwd)
512 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
513 other doesn't. What a disaster. Probably to exclude it. Also
514 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
517 * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
518 usually IN_ATTRIB is the right way to watch deleted files, as the former only
519 fires when a file is actually removed from disk, i.e. the link count drops to
520 zero and is not open anymore, while the latter happens when a file is
521 unlinked from any dir.
523 * port systemctl, busctl, … over to format-table.[ch]'s table formatters
525 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
527 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
529 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
530 files and directories that are left writable for a unit, and which are
531 removed after the unit goes down again. A bit like --ephemeral for
532 systemd-nspawn but for system services. If used together with RootImage= this
533 should reflink the image file itself.
535 Related: add Ephemeral=<path1> <path2> … which would allow marking
536 specific paths only like this.
538 * add CopyFile= or so as unit file setting that may be used to copy files or
539 directory trees from the host to the services RootImage= and RootDirectory=
540 environment. Which we can use for /etc/machine-id and in particular
541 /etc/resolv.conf. Should be smart and do something useful on read-only
542 images, for example fall back to read-only bind mounting the file instead.
544 * show invocation ID in systemd-run output
546 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
548 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
549 and so on, which would mean we could report errors and such.
551 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
554 * introduce DefaultSlice= or so in system.conf that allows changing where we
555 place our units by default, i.e. change system.slice to something
556 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
557 be moved somewhere else too. Finally machined and logind should get similar
558 options so that it is possible to move user session scopes and machines to a
559 different slice too by default. Usecase: people who want to put resources on
560 the entire system, with the exception of one specific service. See:
561 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
563 * maybe rework get_user_creds() to query the user database if $SHELL is used
564 for root, but only then.
566 * be stricter with fds we receive for the fdstore: close them asynchronously
568 * calenderspec: add support for week numbers and day numbers within a
569 year. This would allow us to define "bi-weekly" triggers safely.
571 * sd-bus: add vtable flag, that may be used to request client creds implicitly
572 and asynchronously before dispatching the operation
574 * sd-bus: parse addresses given in sd_bus_set_addresses immediately and not
575 only when used. Add unit tests.
577 * make use of ethtool veth peer info in machined, for automatically finding out
578 host-side interface pointing to the container.
580 * add some special mode to LogsDirectory=/StateDirectory=… that allows
581 declaring these directories without necessarily pulling in deps for them, or
582 creating them when starting up. That way, we could declare that
583 systemd-journald writes to /var/log/journal, which could be useful when we
584 doing disk usage calculations and so on.
586 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
588 * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
590 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
591 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
592 as the unit is running or has a job queued.
594 * support projid-based quota in machinectl for containers
596 * add a way to lock down cgroup migration: a boolean, which when set for a unit
597 makes sure the processes in it can never migrate out of it
599 * blog about fd store and restartable services
601 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
603 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
604 magic meaning and is no longer upgraded to something else if set explicitly.
606 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
607 make it lose its identity, i.e. be anonymous. For this we'd have to patch
608 through the whole tree to make all code deal with the case where no machine
611 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
612 suitable for processing with rrdtool. Add bus API to access this data, and
613 possibly implement a CPULoad property based on it.
615 * beef up pam_systemd to take unit file settings such as cgroups properties as
618 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
619 the quota of a the user indicated in User= via unit file settings, like the
620 other resource management concepts. Would mix nicely with DynamicUser=1. Or
621 alternatively, do this with projids, so that we can also cover services
622 running as root. Quota should probably cover all the special dirs such as
623 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
624 is set, plus the whole disk space any image configured with RootImage=.
626 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
627 disks to see if the UID is already in use.
629 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
630 for all units. It should be both a way to pin units into memory as well as a
631 wait to retrieve their exit data.
633 * expose IO accounting data on the bus, show it in systemd-run --wait and log
634 about it in the resource log message
636 * show whether a service has out-of-date configuration in "systemctl status" by
637 using mtime data of ConfigurationDirectory=.
639 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
640 creates a static, persistent user rather than a dynamic, transient user. We
641 can leverage code from sysusers.d for this.
643 * add some optional flag to ReadWritePaths= and friends, that has the effect
644 that we create the dir in question when the service is started. Example:
646 ReadWritePaths=:/var/lib/foobar
648 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
649 the sd-journal logging socket, and, if the timeout is set to 0, sets
650 O_NONBLOCK on it. That way people can control if and when to block for
653 * hostnamed: populate form factor data from a new hwdb database, so that old
654 yogas can be recognized as "convertible" too, even if they predate the DMI
655 "convertible" form factor
657 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
658 the service cgroup, which is supposed to monitor the service, and when it
659 exits the service is considered failed by its monitor.
661 * track the per-service PAM process properly (i.e. as an additional control
662 process), so that it may be queried on the bus and everything.
664 * add a new "debug" job mode, that is propagated to unit_start() and for
665 services results in two things: we raise SIGSTOP right before invoking
666 execve() and turn off watchdog support. Then, use that to implement
667 "systemd-gdb" for attaching to the start-up of any system service in its
670 * gpt-auto logic: related to the above, maybe support a "secondary" root
671 partition, that is mounted to / and is writable, and where the actual root's
672 /usr is mounted into.
674 * 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
676 * drop nss-myhostname in favour of nss-resolve?
678 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
679 then use that for the setting used in user@.service. It should be understood
680 relative to the configured default value.
682 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
684 * enable LockMLOCK to take a percentage value relative to physical memory
686 * Permit masking specific netlink APIs with RestrictAddressFamily=
688 * nspawn: support that /proc, /sys/, /dev are pre-mounted
690 * define gpt header bits to select volatility mode
692 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
694 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
696 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
698 * ProtectKeyRing= to take keyring calls away
700 * RemoveKeyRing= to remove all keyring entries of the specified user
702 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
703 on PID 1 with the relevant signals, and makes relevant files in /sys and
704 /proc (such as the sysrq stuff) unavailable
706 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
708 * journalctl: make sure -f ends when the container indicated by -M terminates
710 * mount: automatically search for "main" partition of an image has multiple
713 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
714 find a way to map the User=/Group= of the service to the right name. This way
715 a user/group for a service only has to exist on the host for the right
718 * add bus API for creating unit files in /etc, reusing the code for transient units
720 * add bus API to remove unit files from /etc
722 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
724 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
725 kernel doesn't support linkat() that replaces existing files, currently)
727 * transient units: don't bother with actually setting unit properties, we
728 reload the unit file anyway
730 * journald: sigbus API via a signal-handler safe function that people may call
731 from the SIGBUS handler
733 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
735 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
736 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
738 * cache sd_event_now() result from before the first iteration...
740 * PID1: find a way how we can reload unit file configuration for
741 specific units only, without reloading the whole of systemd
743 * add an explicit parser for LimitRTPRIO= that verifies
744 the specified range and generates sane error messages for incorrect
747 * when we detect that there are waiting jobs but no running jobs, do something
749 * push CPUAffinity= also into the "cpuset" cgroup controller
751 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
753 * there's probably something wrong with having user mounts below /sys,
754 as we have for debugfs. for example, src/core/mount.c handles mounts
755 prefixed with /sys generally special.
756 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
758 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
760 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
762 * add a job mode that will fail if a transaction would mean stopping
763 running units. Use this in timedated to manage the NTP service
765 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
767 * The udev blkid built-in should expose a property that reflects
768 whether media was sensed in USB CF/SD card readers. This should then
769 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
770 picked up by systemd unless they contain a medium. This would mirror
771 the behaviour we already have for CD drives.
773 * networkd/udev: implement SR_IOV configuration in .link files:
774 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
776 * hostnamectl: show root image uuid
778 * Find a solution for SMACK capabilities stuff:
779 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
781 * "systemctl preset-all" should probably order the unit files it
782 operates on lexicographically before starting to work, in order to
783 ensure deterministic behaviour if two unit files conflict (like DMs
786 * synchronize console access with BSD locks:
787 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
789 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
790 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
792 * figure out when we can use the coarse timers
794 * add "systemctl start -v foobar.service" that shows logs of a service
795 while the start command runs. This is non-trivial to do without
796 races though, since we should flush out all journal messages before
797 returning from the "systemctl stop".
799 * 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
801 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
803 * maybe allow timer units with an empty Units= setting, so that they
804 can be used for resuming the system but nothing else.
806 * what to do about udev db binary stability for apps? (raw access is not an option)
808 * systemctl: if some operation fails, show log output?
810 * systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #.
811 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
813 * exponential backoff in timesyncd when we cannot reach a server
815 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
817 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
819 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
820 (throughout the codebase, not only PID1)
824 - service registration
825 - service/domain/types browsing
827 - DNS-SD service registration from socket units
828 - resolved should optionally register additional per-interface LLMNR
829 names, so that for the container case we can establish the same name
830 (maybe "host") for referencing the server, everywhere.
831 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
832 - hook up resolved with machined-based address resolution
834 * refcounting in sd-resolve is borked
836 * Add a new verb "systemctl top"
838 * add new gpt type for btrfs volumes
840 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
842 * a way for container managers to turn off getty starting via $container_headless= or so...
844 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
846 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
847 they run added to the initial transaction and thus confuse Type=idle.
849 * add bus api to query unit file's X fields.
851 * gpt-auto-generator:
852 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
853 - Make /home automount rather than mount?
855 * add generator that pulls in systemd-network from containers when
856 CAP_NET_ADMIN is set, more than the loopback device is defined, even
857 when it is otherwise off
859 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
861 * implement Distribute= in socket units to allow running multiple
862 service instances processing the listening socket, and open this up
866 - implement per-slice CPUFairScheduling=1 switch
867 - introduce high-level settings for RT budget, swappiness
868 - how to reset dynamically changed unit cgroup attributes sanely?
869 - when reloading configuration, apply new cgroup configuration
870 - when recursively showing the cgroup hierarchy, optionally also show
871 the hierarchies of child processes
874 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
876 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
878 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
880 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
882 * 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
884 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
886 * If we try to find a unit via a dangling symlink, generate a clean
887 error. Currently, we just ignore it and read the unit from the search
890 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
892 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
894 * load .d/*.conf dropins for device units
898 - GetAllProperties() on a non-existing object does not result in a failure currently
899 - port to sd-resolve for connecting to TCP dbus servers
900 - 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
901 - see if we can drop more message validation on the sending side
902 - add API to clone sd_bus_message objects
903 - longer term: priority inheritance
905 - NameLost/NameAcquired obsolete
908 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
911 - allow multiple signal handlers per signal?
912 - document chaining of signal handler for SIGCHLD and child handlers
913 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
914 - maybe support iouring as backend, so that we allow hooking read and write
915 operations instead of IO ready events into event loops. See considerations
917 http://blog.vmsplice.net/2020/07/rethinking-event-loop-integration-for.html
919 * investigate endianness issues of UUID vs. GUID
921 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
922 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
924 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
926 * add a pam module that on password changes updates any LUKS slot where the password matches
929 - add unit tests for config_parse_device_allow()
931 * seems that when we follow symlinks to units we prefer the symlink
932 destination path over /etc and /usr. We should not do that. Instead
933 /etc should always override /run+/usr and also any symlink
936 * when isolating, try to figure out a way how we implicitly can order
937 all units we stop before the isolating unit...
939 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
941 * Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add
942 ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at
943 https://github.com/systemd/systemd/pull/15109#issuecomment-607740136.
945 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
946 that the boot loader should be installed to the ESP. Define a way
947 how an installer can figure out whether a BLS compliant boot loader
950 * think about requeuing jobs when daemon-reload is issued? usecase:
951 the initrd issues a reload after fstab from the host is accessible
952 and we might want to requeue the mounts local-fs acquired through
955 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
957 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
959 * shutdown logging: store to EFI var, and store to USB stick?
961 * merge unit_kill_common() and unit_kill_context()
964 - honor language efi variables for default language selection (if there are any?)
965 - honor timezone efi variables for default timezone selection (if there are any?)
966 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
968 - recognize the case when not booted on EFI
970 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
972 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
974 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
977 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
978 - logind: wakelock/opportunistic suspend support
979 - Add pretty name for seats in logind
980 - logind: allow showing logout dialog from system?
981 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
982 - if pam_systemd is invoked by su from a process that is outside of a
983 any session we should probably just become a NOP, since that's
984 usually not a real user session but just some system code that just
986 - logind: make the Suspend()/Hibernate() bus calls wait for the for
987 the job to be completed. before returning, so that clients can wait
988 for "systemctl suspend" to finish to know when the suspending is
990 - logind: when the power button is pressed short, just popup a
991 logout dialog. If it is pressed for 1s, do the usual
992 shutdown. Inspiration are Macs here.
993 - expose "Locked" property on logind sesison objects
994 - maybe allow configuration of the StopTimeout for session scopes
995 - rename session scope so that it includes the UID. THat way
996 the session scope can be arranged freely in slices and we don't have
997 make assumptions about their slice anymore.
998 - follow PropertiesChanged state more closely, to deal with quick logouts and
1000 - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set
1003 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
1004 - journald: also get thread ID from client, plus thread name
1005 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
1006 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
1007 - fall back to /dev/log based logging in libsystemd-journal, if we cannot log natively?
1008 - declare the local journal protocol stable in the wiki interface chart
1009 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
1010 - journald: when dropping msgs due to ratelimit make sure to write
1011 "dropped %u messages" not only when we are about to print the next
1012 message that works, but already after a short timeout
1013 - check if we can make journalctl by default use --follow mode inside of less if called without args?
1014 - maybe add API to send pairs of iovecs via sd_journal_send
1015 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
1016 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
1017 and !FOOBAR for events without FOOBAR.
1018 - journal: store timestamp of journal_file_set_offline() in the header,
1019 so it is possible to display when the file was last synced.
1020 - 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.
1021 - journal: find a way to allow dropping history early, based on priority, other rules
1022 - journal: When used on NFS, check payload hashes
1023 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
1024 - refuse taking lower-case variable names in sd_journal_send() and friends.
1025 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
1026 - journal: deal nicely with byte-by-byte copied files, especially regards header
1027 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
1028 - Replace utmp, wtmp, btmp, and lastlog completely with journal
1029 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
1030 - when a kernel driver logs in a tight loop, we should ratelimit that too.
1031 - journald: optionally, log debug messages to /run but everything else to /var
1032 - journald: when we drop syslog messages because the syslog socket is
1033 full, make sure to write how many messages are lost as first thing
1034 to syslog when it works again.
1035 - journald: allow per-priority and per-service retention times when rotating/vacuuming
1036 - journald: make use of uid-range.h to managed uid ranges to split
1038 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
1039 - improve journalctl performance by loading journal files
1040 lazily. Encode just enough information in the file name, so that we
1041 do not have to open it to know that it is not interesting for us, for
1042 the most common operations.
1043 - man: document that corrupted journal files is nothing to act on
1044 - rework journald sigbus stuff to use mutex
1045 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
1046 services that run under their own user ids, and use User= (but only
1047 in a world where userns is ubiquitous since otherwise we cannot
1048 invoke those daemons on the host AND in a container anymore). Also,
1049 if LimitNPROC= is used without User= we should warn and refuse
1051 - journalctl --verify: don't show files that are currently being
1052 written to as FAIL, but instead show that their are being written to.
1053 - add journalctl -H that talks via ssh to a remote peer and passes through
1055 - add a version of --merge which also merges /var/log/journal/remote
1056 - journalctl: -m should access container journals directly by enumerating
1057 them via machined, and also watch containers coming and going.
1058 Benefit: nspawn --ephemeral would start working nicely with the journal.
1059 - assign MESSAGE_ID to log messages about failed services
1060 - check if loop in decompress_blob_xz() is necessary
1062 * add a test if all entries in the catalog are properly formatted.
1063 (Adding dashes in a catalog entry currently results in the catalog entry
1064 being silently skipped. journalctl --update-catalog must warn about this,
1065 and we should also have a unit test to check that all our message are OK.)
1068 - document that deps in [Unit] sections ignore Alias= fields in
1069 [Install] units of other units, unless those units are disabled
1070 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
1071 - document that service reload may be implemented as service reexec
1072 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
1073 - document systemd-journal-flush.service properly
1074 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
1075 - man: document the very specific env the shutdown drop-in tools live in
1076 - man: add more examples to man pages,
1077 - in particular an example how to do the equivalent of switching runlevels
1078 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
1079 - document root=gpt-auto properly
1082 - add systemctl switch to dump transaction without executing it
1083 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
1084 - "systemctl disable" on a static unit prints no message and does
1085 nothing. "systemctl enable" does nothing, and gives a bad message
1086 about it. Should fix both to print nice actionable messages.
1087 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
1088 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
1089 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
1090 - systemctl: "Journal has been rotated since unit was started." message is misleading
1091 - systemctl status output should include list of triggering units and their status
1094 - "systemctl mask" should find all names by which a unit is accessible
1095 (i.e. by scanning for symlinks to it) and link them all to /dev/null
1098 - timer units should get the ability to trigger when:
1100 - Modulate timer frequency based on battery state
1102 * add libsystemd-password or so to query passwords during boot using the password agent logic
1104 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
1106 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
1108 * make repeated alt-ctrl-del presses printing a dump
1110 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
1112 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
1115 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
1116 with seccomp. That should provide us with a useful log buffer that
1117 systemd can log to during early boot, and disconnect container logs
1118 from the kernel's logs.
1119 - as soon as networkd has a bus interface, hook up --network-interface=,
1120 --network-bridge= with networkd, to trigger netdev creation should an
1121 interface be missing
1122 - a nice way to boot up without machine id set, so that it is set at boot
1123 automatically for supporting --ephemeral. Maybe hash the host machine id
1124 together with the machine name to generate the machine id for the container
1125 - fix logic always print a final newline on output.
1126 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
1127 - should optionally support receiving WATCHDOG=1 messages from its payload
1129 - optionally automatically add FORWARD rules to iptables whenever nspawn is
1130 running, remove them when shut down.
1133 - add an API so that libvirt-lxc can inform us about network interfaces being
1134 removed or added to an existing machine
1135 - "machinectl migrate" or similar to copy a container from or to a
1136 difference host, via ssh
1137 - introduce systemd-nspawn-ephemeral@.service, and hook it into
1138 "machinectl start" with a new --ephemeral switch
1139 - "machinectl status" should also show internal logs of the container in
1141 - "machinectl history"
1143 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
1144 shell in it, and marks it read-only after use
1147 - cryptsetup-generator: allow specification of passwords in crypttab itself
1148 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
1150 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
1151 https://bugs.freedesktop.org/show_bug.cgi?id=54712
1153 * add a dependency on standard-conf.xml and other included files to man pages
1155 * MountFlags=shared acts as MountFlags=slave right now.
1157 * properly handle loop back mounts via fstab, especially regards to fsck/passno
1159 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
1164 - add trigger --subsystem-match=usb/usb_device device
1165 - reimport udev db after MOVE events for devices without dev_t
1167 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
1169 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
1172 - save coredump in Windows/Mozilla minidump format
1173 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
1175 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
1177 * be able to specify a forced restart of service A where service B depends on, in case B
1178 needs to be auto-respawned?
1181 - apply "x" on "D" too (see patch from William Douglas)
1182 - instead of ignoring unknown fields, reject them.
1183 - creating new directories/subvolumes/fifos/device nodes
1184 should not follow symlinks. None of the other adjustment or creation
1185 calls follow symlinks.
1187 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
1189 * verify that the AF_UNIX sockets of a service in the fs still exist
1190 when we start a service in order to avoid confusion when a user
1191 assumes starting a service is enough to make it accessible
1193 * Make it possible to set the keymap independently from the font on
1194 the kernel cmdline. Right now setting one resets also the other.
1196 * and a dbus call to generate target from current state
1198 * write blog stories about:
1199 - hwdb: what belongs into it, lsusb
1200 - enabling dbus services
1201 - how to make changes to sysctl and sysfs attributes
1203 - how to pass throw-away units to systemd, or dynamically change properties of existing units
1204 - testing with Harald's awesome test kit
1206 - how to develop against journal browsing APIs
1207 - the journal HTTP iface
1208 - non-cgroup resource management
1209 - dynamic resource management with cgroups
1210 - refreshed, longer missions statement
1211 - calendar time events
1212 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
1213 - how to create your own target
1214 - instantiated apache, dovecot and so on
1215 - hooking a script into various stages of shutdown/rearly booot
1217 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
1219 * dot output for --test showing the 'initial transaction'
1222 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
1223 log both units as UNIT=, so that journalctl -u triggers on both.
1224 - generate better errors when people try to set transient properties
1225 that are not supported...
1226 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
1227 - maybe introduce WantsMountsFor=? Usecase:
1228 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
1229 - recreate systemd's D-Bus private socket file on SIGUSR2
1230 - move PAM code into its own binary
1231 - when we automatically restart a service, ensure we restart its rdeps, too.
1232 - hide PAM options in fragment parser when compile time disabled
1233 - Support --test based on current system state
1234 - 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().
1235 - after deserializing sockets in socket.c we should reapply sockopts and things
1236 - drop PID 1 reloading, only do reexecing (difficult: Reload()
1237 currently is properly synchronous, Reexec() is weird, because we
1238 cannot delay the response properly until we are back, so instead of
1239 being properly synchronous we just keep open the fd and close it
1240 when done. That means clients do not get a successful method reply,
1241 but much rather a disconnect on success.
1242 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
1243 - when a bus name of a service disappears from the bus make sure to queue further activation requests
1246 - allow port=0 in .socket units
1247 - maybe introduce ExecRestartPre=
1248 - add ReloadSignal= for configuring a reload signal to use
1249 - implement Register= switch in .socket units to enable registration
1250 in Avahi, RPC and other socket registration services.
1251 - allow Type=simple with PIDFile=
1252 https://bugzilla.redhat.com/show_bug.cgi?id=723942
1253 - allow writing multiple conditions in unit files on one line
1254 - introduce Type=pid-file
1255 - introduce mix of BindTo and Requisite
1256 - add a concept of RemainAfterExit= to scope units
1257 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
1258 - add verification of [Install] section to systemd-analyze verify
1261 - Make sure ID_PATH is always exported and complete for
1262 network devices where possible, so we can safely rely
1266 - add support for more attribute types
1267 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
1270 - add more keys to [Route] and [Address] sections
1271 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
1272 - add reduced [Link] support to .network files
1273 - properly handle routerless dhcp leases
1274 - work with non-Ethernet devices
1275 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
1276 - the DHCP lease data (such as NTP/DNS) is still made available when
1277 a carrier is lost on a link. It should be removed instantly.
1278 - expose in the API the following bits:
1279 - option 15, domain name
1280 - option 12, hostname and/or option 81, fqdn
1281 - option 123, 144, geolocation
1282 - option 252, configure http proxy (PAC/wpad)
1283 - provide a way to define a per-network interface default metric value
1284 for all routes to it. possibly a second default for DHCP routes.
1285 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1286 support Name=foo*|bar*|baz ?
1287 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1288 - whenever uplink info changes, make DHCP server send out FORCERENEW
1290 * Figure out how to do unittests of networkd's state serialization
1293 - figure out how much we can increase Maximum Message Size
1296 - add functions to set previously stored IPv6 addresses on startup and get
1297 them at shutdown; store them in client->ia_na
1298 - write more test cases
1299 - implement reconfigure support, see 5.3., 15.11. and 22.20.
1300 - implement support for temporary adressess (IA_TA)
1301 - implement dhcpv6 authentication
1302 - investigate the usefulness of Confirm messages; i.e. are there any
1303 situations where the link changes without any loss in carrier detection
1305 - some servers don't do rapid commit without a filled in IA_NA, verify
1312 - natively watch for dbus-*.service symlinks (PENDING)
1313 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1315 * make cryptsetup lower --iter-time
1317 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1319 * /usr/bin/service should actually show the new command line
1321 * 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=
1323 * neither pkexec nor sudo initialize environ[] from the PAM environment?
1325 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1327 * register catalog database signature as file magic
1329 * zsh shell completion:
1330 - <command> <verb> -<TAB> should complete options, but currently does not
1331 - systemctl add-wants,add-requires
1333 * systemctl status should know about 'systemd-analyze calendar ... --iterations='
1334 * If timer has just OnInactiveSec=..., it should fire after a specified time
1335 after being started.
1339 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1341 * check for strerror(r) instead of strerror(-r)
1345 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1347 * use secure_getenv() instead of getenv() where appropriate
1349 * link up selected blog stories from man pages and unit files Documentation= fields
1350 String is not UTF-8 clean, ignoring assignment
