Fedora 20:
External:

CGroup Rework Completion:
* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
* implement system-wide DefaultCPUAccounting=1 switch (and similar for blockio, memory?)
* implement per-slice CPUFairScheduling=1 switch
* handle jointly mounted controllers correctly
* introduce high-level settings for RT budget, swappiness
* Fedora: post FPC ticket to move add %tmpfiles_create to the packaging guidelines
Features:
* cgroups:
- implement system-wide DefaultCPUAccounting=1 switch (and similar for blockio, memory?)
- implement per-slice CPUFairScheduling=1 switch
- handle jointly mounted controllers correctly
- introduce high-level settings for RT budget, swappiness
- how to reset dynamically changed unit cgroup attributes sanely?
- when reloading configuration, apply new cgroup configuration
- when recursively showing the cgroup hierarchy, optionally also show
the hierarchies of child processes
* transient units:
- allow creating auxiliary units with the same call
- add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
- ensure scope units may be started only a single time
* switch to SipHash for hashmaps/sets?
* general: get rid of readdir_r/dirent_storage stuff, it's unnecessary on Linux
* add API to clone sd_bus_message objects
* sd-bus: synthesized messages should get serial number (uint32_t) -1
* sd-event: allow multiple signal handlers per signal
* when we detect low battery and no AC on boot, show pretty splash and refuse boot
* move libasyncns into systemd as libsystemd-asyncns
* calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
* sd-bus: when triggering property change events, allow a NULL strv indicate that all properties listed as such are send out as changed
* sd-bus: enforce signatures on response messages
* sd-bus: see if we can drop more message validation on the sending side
* sd-bus: introduce sd_bus_creds object and attach it to messages as well as allow querying it for names
* sd-bus: support "const" properties as flag
* sd-event: when a handler returns an error, just turn off its event
source, but do not return anything up to the event loop
caller. Instead add parameter to sd_event_request_quit() to take
retval. This way errors rippling upwards are the option, not the
default
* sd-event: child pid handling: first invoke waitid(WNOHANG) and call event handler, only afterwards reap the process
* sd-event: native support for watchdog stuff
* machined, localed: when we try to kill an empty cgroup, generate an ESRCH call over the bus
* sd-bus: SD_BUS_COMMENT() macro for inclusion in vtables, syntax inspired by gdbus
* machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
* add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
* systemctl: rework wait filter to not require match callback
* unify dispatch table in systemctl_main() and friends
* bus: access policy as vtable flag
* journalctl: support -M to read journal of containers and determine journal directory from root directory of container
* tmpfiles: to make sure we don't delete unpacked tarballs with old timestamps right-away never delete stuff that is inside a directory with a new mtime
* "systemctl mask" should find all names by which a unit is accessible
(i.e. by scanning for symlinks to it) and link them all to /dev/null
* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
* remove NSS usage from PID 1 (notably the specifiers)
* socket-proxyd:
- Support multiple inherited sockets mapped to different remote hosts
- Use a nonblocking alternative to getaddrinfo
* "systemctl cat" or "systemctl view" command or or so, that cats the backing unit file of a service, plus its drop-ins and shows them in a pager
* socket-proxyd:Use a nonblocking alternative to getaddrinfo
* 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
* Add a new Distribute=$NUMBER key to socket units that makes use of SO_REUSEPORT to distribute network traffic on $NUMBER instances
* tmpfiles: when applying ownership to /run/log/journal, also do this for the journal fails contained in it
* we probably should replace the left-over uses of strv_append() and replace them by strv_push() or strv_extend()
* move config_parse_path_strv() out of conf-parser.c

* Fedora: post FPC ticket to move add %tmpfiles_create to the packaging guidelines
* make sure gdm doesn't use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
* when parsing calendar timestamps support the UTC timezone (even if we won't support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
* when a kernel driver logs in a tight loop, we should ratelimit that too.
* "systemctl disable" of a unit instance removes all symlinks, but should
only remove the instance symlink (systemctl disable of a template
unit however should remove them all).
* journald: optionally, log debug messages to /run but everything else to /var
* systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
* journald: when we drop syslog messages because the syslog socket is
full, make sure to write how many messages are lost as first thing
to syslog when it works again.

* transient units: allow creating auxiliary units with the same call
* how to reset dynamically changed attributes sanely?
* when reloading configuration, apply new cgroup configuration
* journald: make sure ratelimit is actually really per-service with the new cgroup changes
* gparted needs to disable auto-activation of mount units somehow, or
maybe we should stop doing auto-activation of this after boot
entirely. https://bugzilla.gnome.org/show_bug.cgi?id=701676
Maybe take a BSD lock at the disk device node and teach udev to
check for that and suppress event handling.
* when recursively showing the cgroup hierarchy, optionally also show
the hierarchies of child processes
* document logic of auto/noauto and fail/nofail in fstab in systemd.mount or systemd-fstab-generator man page
* something pulls in pcre as shared object dependency into our daemons such as hostnamed.
* document systemd-journal-flush.service properly
* change systemd-journal-flush into a service that stays around during
boot, and causes the journal to be moved back to /run on shutdown,
so that we don't keep /var busy. This needs to happen synchronously,
hence doing this via signals is not going to work.
* allow implementation of InaccessibleDirectories=/ plus
ReadOnlyDirectories=... for whitelisting files for a service.
* libsystemd-bus:
- default policy (allow uid == 0 and our own uid)
- access policy as vtable flag
- enforce alignment of pointers passed in
- when kdbus doesn't take our message without memfds, try again with memfds
- implement translator service
- port systemd to new library
- implement busname unit type in systemd
- move to gvariant
- merge busctl into systemctl or so?
- synthesize sd_bus_message objects from kernel messages
