[systemd-devel] [PATCH] correctly mark system reboot

[Andrey Borzenkov]

It is expected that system will put "reboot" in wtmp to mark
when it starts coming up. This is looked for by "who -b" and is
used by "last" to calculate correct time spent by various programs.
Add systemd-update-utmp-reboot.service which is started as soon
as possible after local-fs.target to mark reboot.
