Features:
+* introduce "machinectl shell" that is like systemd-run -M foo /bin/bash -t but also adds PAMName=login
+
+* allow loging into host with "machinectl login".
+
* consider throwing a warning if a service declares it wants to be "Before=" a .device unit.
* "systemctl edit" should know a mode to create a new unit file
* If we show an error about a unit (such as not showing up) and it has no Description string, then show a description string generated form the reverse of unit_name_mangle().
-* fedup: add --unit to systemctl switch-root somehow
-* fedup: do not delete initrd on switch-root
-* fedup: generator
-
* clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
* on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
