-  as a built-in module option as an env variable. Systemd should not pass-on

-* introduce high-level settings for RT budget, swappiness
+* increase journal files by a few MB each time, instead of piecemeal

 
 

-* wiki: document new bus APIs of PID 1
+* add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt

 
 

-* Send SIGHUP and SIGTERM in session scopes
+* systemctl: rework wait filter to not require match callback

 
 

-Features:
+* 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
+  - Until we can start daemons directly, find a less ugly, less racy alternative than shell scripts for the second man page example.
+  - Support starting daemons directly without requiring a shell script; update man pages
+
+* optimize the cgroup propagation bits, especially unit_get_members_mask(), cgroup_context_get_mask()
+
+* "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
+
+* 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
+
+* libdsystemd-bus should expose utf8 validation calls
+
+* After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
+
+* 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.
+
+* 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

+
+* systemctl status output should should include list of triggering units and their status
+
+* for transient units, instead of writing out drop-ins for all properties consider serializing them in the normal serialization stream
+
+* logind: when logging out, remove user-owned sysv and posix IPC objects
+
+* session scopes/user unit: add RequiresMountsFor for the home directory of the user
+
