Please, *don't* restart the service. If you fuck up your sshd_config
and you have no OOB remote access you're lost. `service sshd reload' is 
something more recommendable as it doesn't drop your current SSH sessions.

Just for the records:
Another way would be to set PermitRootLogin to without-password and thus
pinning it down to logins via ssh-keys only.
