Hello,

Does the -r switch in shutdown(8) actually work?

I have never used it.

Best,
-Michael

Yes. It has worked in all Linux systems I've used for years
(and several non-Linux Unix-based systems like HP-UX).

In the past "shutdown -r now" and "reboot" differed, e.g., reboot
didn't sync or run shutdown scripts (and thus shutdown was sometimes
recommended as the "safe" or "clean" way to reboot), but nowadays
they're identical apart from some different options (notably, reboot
has the "-f" option for "dirty" reboot, but it's not default anymore).
People generally use whichever they're used to.

Today shutdown, reboot, halt and poweroff are all symlinks to
systemctl in Debian and Ubuntu at least, but options and defaults
differ depending on which name it is called with.

E.g., Debian Buster:

$ ls -l /sbin/{shutdown,reboot,halt,poweroff}
lrwxrwxrwx 1 root root 14 Mar 18 21:59 /sbin/halt -> /bin/systemctl
lrwxrwxrwx 1 root root 14 Mar 18 21:59 /sbin/poweroff -> /bin/systemctl
lrwxrwxrwx 1 root root 14 Mar 18 21:59 /sbin/reboot -> /bin/systemctl
lrwxrwxrwx 1 root root 14 Mar 18 21:59 /sbin/shutdown -> /bin/systemctl

I also tried this on my IPFire test system before submitting the patch and can confirm that -r (and -F) work as expected :)

Thanks for the detailed explanation!
