Surprisingly, in Debian the shutdown binary is in the systemd-sysv
package and will thus vanish as soon as we¹ eventually get rid of the
last init script, but I am pretty sure that shutdown nowadays just
issues a command to systemd like the appropriate systemctl reboot or
systemctl halt.
 
Unfortunately, systemd doesn't offer a native equivalent to a timed
shutdown, so one has to do an arcane construct involving systemd-run and
a transient unit to achive that, but that's just the way things are. Not
everything around systemd is good.
 
That being said, don't feed the troll any more.

Hi Marc,

Just checked the man page for shutdown(8), and it says it was
added to systemd 250.  It supports the timespec and wall parameters,
but I'm not sure how well...

Anyway, I'm running 255 on Linux Mint 22.1, which
seems to have been pulled in from the System76 repo that I use:

$ systemd --version
systemd 255 (255.4-1ubuntu8.6pop0~1742486928~24.04~40a1bd7~dev)
[...]
