If there are ever any problems with your network configuration you won't
be able to log in to fix them. Not even on the console - there will
simply not be a login prompt.

Same problem is caused by the mythtv-backend.service file: if there is a
problem of any kind (e.g. with a tuner that's been added to After= and
Wants= lines) then the system doesn't complete booting and you can't log
in to troubleshoot. Truly horrendous design.

I would like multi-user.target to be reached ASAP and with as few
dependencies as possible. It can take 3 minutes for all of my pvrusb2
tuners to be initialised, and I don't want to wait for them to be able
to log in.
