OTOH we could and IMO should use

https://packages.ubuntu.com/bionic/amd64/systemd-sysv/filelist

shutdown -r now

to reboot right "now" or at a specified time on probably all Linux
and BSD.

AFAIK "shutdown" doesn't belong to the Portable Operating System
Interface standard, but it's anyway a portable command.

IMO we shouldn't lose too much portability.
