Fedup is being replaced by a dnf plugin that relies on systemd offline
updates as per
https://fedoraproject.org/wiki/Changes/DNF_System_Upgrades
* 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
