The usual procedure is to get console access. The cheapest and
easiest way of doing that is to use a null-modem cable to connect the
serial port to a neighbouring machine and run tip(1) or some other
terminal emulator there. If you haven't got another machine handy,
you might be able to use a modem to provide yourself with a remote
console -- shades of the days of big-iron mainframe type systems.

Getting into single user mode remotely is easy. It's the getting out
that's hard.

If you're going to do this at all, it's probably better to save the
reboot until after all of the installworld/installkernel/mergemaster
steps.

You certainly can do this, and the vast majority of the time it will
work OK. However, if things don't go smoothly you're going to be left
up a gum tree with a non-working server and no way to recover or
back-out changes. Whether that's an acceptable risk is a judgement
call you'll have to make.
Cheers,
Matthew
