[systemd-devel] systemd reboot problem

[Brian Kroth]

In that case, you could also just do something like this:
# for i in {u,s,b}; do echo $i > /proc/sysrq-trigger; done
For "Remount read-only, Sync, (re)Boot".  There are also hotkey sequences
to do that (the modern equivalent of the three fingered salute) which might
be more appropriate in the case of a hanging reboot.  Have a look at the
dmesg output of "echo ? > /proc/sysrq-trigger" or the sysrq-trigger info in
the kernel documentation for other info.

Cheers,
Brian
