Oh, ok. I thought it wasn't possible.

I'm happy that root is just a name for uid 0, but what about
processes that need to be started at boot time? Will it be
possible to run these at boot time without an entry for root in
the password file, and without the setuid bits on executable
binaries?

If it is, then this seems like a fine security measure for a
bastion host.
