 Features:
 

-* move systemctl set-log-level to systemd-analyze?
+* move config_parse_path_strv() out of conf-parser.c

 
 

-* fix killing spree logic in systemd-user-sessions
+* libdsystemd-bus should expose utf8 validation calls

 
 

-* logind: implement session kill exceptions
+* When using "systemd status" on a slice unit also show all messages
+  matching _SYSTEMD_SLICE= not just _SYSTEMD_UNIT=

 
 

-* fix machine regstration to forward property array
+* After coming back from hibernation reset hibernation swap partition

 
 

-* fix loginctl cgroup enumeration
+* If we try to find a unit via a dangling symlink generate a clean
+  error. Currently we just ignore it and read the unit from the search
+  path anyway.

 
 

-* move "systemctl dump" to systemd-analyze
+* When a Type=forking service fails and needed another service that
+  service is not cleaned up again when it has StopWhenUnneeded=yes
+  http://lists.freedesktop.org/archives/systemd-devel/2013-July/012141.html

 
 

-* introduce "mainpid" for scopes
+* backlight: properly handle multiple backlight devices for the same
+  hardware: at shutdown we should only save the backlight setting for
+  the "best" way to access the backlight. Strategy should be: at
+  shutdown, ignore all backlights that are connected to a non-eDP or
+  non-LVDS port, and then prefer the firmware device over platform
+  device over raw device per-PCI card. Delete all old data. At boot
+  simply apply whatever data we find. Also see
+  http://cgit.freedesktop.org/libbacklight/tree/libbacklight.c#n194

 
 

-* add a fixed dbus path for "my own unit", "my own session", ... to PID1, logind, ...
+* rfkill: save/restore soft rfkill status across reboots

 
 

-* add implicit slice for instantiated services
+* refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up

 
 

-* service_coldplug() appears to reinstall the wrong stop timeout watch?
+* ensure scope units may be started only a single time

 
 

-* transient units: allow creating auxiliary units with the same call
+* document that in instead of FsckPassNo= people should just add a manual dep to systemd-fsck@.service to their mount units.

 
 

-* make BlockIODeviceWeight=, BlockIODeviceBandwidth= runtime settable
+* better error message if you run systemctl without systemd running

 
 

-* split up BlockIOWeight= and BlockIODeviceWeight=
+* systemctl status output should should include list of triggering units and their status

 
 

-* introduce high-level settings for RT budget, swapiness
+* for transient units, instead of writing out drop-ins for all properties consider serializing them in the normal serialization stream

 
 

-* how to reset dynamically changed attributes sanely?
+* logind: when logging out, remove user-owned sysv and posix IPC objects

 
 

-* when reloading configuration, apply new cgroup configuration
+* session scopes/user unit: add RequiresMountsFor for the home directory of the user

 
 

-* implement system-wide DefaultCPUAccounting=1 switch (and similar for blockio, memory?)
+* add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.

 
 

-* implement per-slice CPUFairScheduling=1 switch
+* journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?

 
 

-* handle jointly mounted controllers correctly
+* given that logind/machined now let PID 1 do all nasty work we can
+  probably reduce the capability set they retain substantially.

 
 

-* journald: make sure ratelimit is actually really per-service with the new cgroup changes
+* btrfs raid assembly: some .device jobs stay stuck in the queue
+
+* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
+
+* 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, 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

 
 

-* move systemctl dump to systemd-analyze
+* systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)

 
 

-* libsystemd-logind: sd_session_is_active() and friends: verify
-  validity of session name before appending it to a path
+* 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.

 
 

-* logind: when a PAM client calls ReleaseSession() start a timeout and
-  kill the session entirely after that is reached.
+* man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
