+* the default stop timeout for units is not documented anywhere.
+
+* .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC
+
+* rm_rf() should be able to remove subvolumes
+
+* systemd-run should support a mode where we wait for the unit to be started up
+
+* create a btrfs qgroup for /var/lib/machines, and add all container
+ subvolumes we create to it.
+
+* nspawn: add --overlay= to support overlay file systems, similar to
+ --tmpfs= and --bind=.
+
+* When logging about multiple units (stopping BoundTo units, conflicts, etc.),
+ log both units as UNIT=, so that journalctl -u triggers on both.
+
+* to allow "linking" of nspawn containers, extend --network-bridge= so
+ that it can dynamically create bridge interfaces that are refcounted
+ by the containers on them. For each group of containers to link together
+
+* journalctl --verify: don't show files that are currently being
+ written to as FAIL, but instead show that their are being written
+ to.
+
+* assign MESSAGE_ID to log messages about failed services
+
+* coredump: make the handler check /proc/$PID/rlimits for RLIMIT_CORE,
+ and supress coredump if turned off. Then change RLIMIT_CORE to
+ infinity by default for all services. This then allows per-service
+ control of coredumping.
+
+* generate better errors when people try to set transient properties
+ that are not supported...

+
+* PID 1: when invoking systemctl preset-all on first boots, operate in
+ an exclusively additive way, i.e. never remove any pre-existing
+ symlinks, only add new ones.
+
+* Introduce $LISTEN_NAMES to complement $LISTEN_FDS, containing a
+ colon separated list of identifiers for the fds passed.
+
+* when the fstab-generator runs in the initrd, it should create a /dev/null mask for systemd-fsck-root.service, to avoid that the the root fs is fsck'ed twice.
+
+* maybe introduce WantsMountsFor=? Usecase:
+ http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
+
+* rework kexec logic to use new kexec_file_load() syscall, so that we
+ don't have to call kexec tool anymore.
