+CGroup Rework Completion:
+
+* introduce "mainpid" for scopes (or maybe not?)
+
+* implement system-wide DefaultCPUAccounting=1 switch (and similar for blockio, memory?)
+
+* implement per-slice CPUFairScheduling=1 switch
+
+* handle jointly mounted controllers correctly

 Features:
 

-* fix killing spree logic in systemd-user-sessions
+* unlink PID files of units after exit

 
 

-* logind: implement session kill exceptions
+* tiny tool that saves/restores backlight

 
 

-* fix machine regstration to forward property array
+* systemctl status output should should include list of triggering units and their status

 
 

-* fix loginctl cgroup enumeration
+* for transient units, instead of writing out drop-ins for all properties consider serializing them in the normal serialization stream

 
 

-* move "systemctl dump" to systemd-analyze
+* logind: when logging out, remove user-owned sysv and posix IPC objects

 
 

-* introduce "mainpid" for scopes
+* session scopes/user unit: add RequiresMountsFor for the home directory of the user

 
 

-* add a fixed dbus path for "my own unit", "my own session", ... to PID1, logind, ...
+* add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.

 
 

-* add implicit slice for instantiated services
+* journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?

 
 

-* service_coldplug() appears to reinstall the wrong stop timeout watch?
+* given that logind/machined now let PID 1 do all nasty work we can
+  probably reduce the capability set they retain substantially.

 
 

-* transient units: allow creating auxiliary units with the same call
+* btrfs raid assembly: some .device jobs stay stuck in the queue

 
 

-* make BlockIODeviceWeight=, BlockIODeviceBandwidth= runtime settable
+* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.

 
 

-* split up BlockIOWeight= and BlockIODeviceWeight=
+* Fedora: post FPC ticket to move add %tmpfiles_create to the packaging guidelines

 
 

-* introduce high-level settings for RT budget, swapiness
+* make sure gdm doesn't use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd

 
 

-* how to reset dynamically changed attributes sanely?
+* 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 reloading configuration, apply new cgroup configuration
+* when a kernel driver logs in a tight loop we should ratelimit that too.

 
 

-* implement system-wide DefaultCPUAccounting=1 switch (and similar for blockio, memory?)
+* "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).

 
 

-* implement per-slice CPUFairScheduling=1 switch
+* journald: optionally, log debug messages to /run but everything else to /var

 
 

-* handle jointly mounted controllers correctly
+* systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)

 
 

-* journald: make sure ratelimit is actually really per-service with the new cgroup changes
+* do we really need both hasprefix() and startswith()?
+
+* 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.
+
+* man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
+
+* load .d/*.conf dropins for device units
