+* support systemd.whitelist=/systemd.blacklist= on the kernel command
+ line.
+
+* Find a way to replace /var/run, /var/lock directories with
+ symlinks during an RPM package upgrade (filesystem.rpm or systemd.rpm).
+ We soon want to get rid of var-run.mount var-lock.mount units:
+
+ if mountpoint /run ; then
+ umount /var/run || :
+ else
+ mount --move /var/run /run || mount --bind /var/run /run
+ fi
+ mv /var/run /var/.run.save
+ ln -s /run /var/run
+ echo "R /var/.run.save" > /etc/tmpfiles.d/remove-run-save.conf
+
+* when key file cannot be found, read it from kbd in cryptsetup
+
+* add switch to systemctl to show enabled but not running services. Or
+ another switch that shows service that have been running since
+ booting but aren't running anymore.
+
+* reuse mkdtemp namespace dirs in /tmp?
+
+* recreate systemd's D-Bus private socket file on SIGUSR2
+
+* be more specific what failed:
+ ...
+ Unmounting file systems.
+ Not all file systems unmounted, 1 left.
+ Disabling swaps.
+ Detaching loop devices.
+ Detaching DM devices.
+ Cannot finalize remaining file systems and devices, trying to kill remaining processes.
+ Unmounting file systems.
+ Not all file systems unmounted, 1 left.
+ Cannot finalize remaining file systems and devices, giving up.
+ ...
+
+* check for compiled-in, but not active selinux, and don't print any warnings
+ about policy loading. Probably check for available selinux in /proc/filesystems,
+ and check for active selinux with getcon_raw() == "kernel"
+
+* Support --test based on current system state
+
+* consider services with no [Install] section and stored in /lib enabled by "systemctl is-enabled"
+
+* systemctl enable as D-Bus call
