Feature request: "Restart to ..." option

[Ralf Mardorf]

If you need it right now, you could write a script, however, that's not
the reason for my reply. The reason is, that I want to mention, that
sometimes a reboot isn't required, chroot or systemd-nspawn makes it
unnecessary to reboot, at least for some purpose.

sudo systemd-nspawn -qD /mnt/point/of/another/linux/install
sudo systemd-nspawn -bqD /mnt/point/of/another/linux/install

Regards,
Ralf
