In fact, you can use any port from 10000 to 10003.  They map to
/dev/console and /dev/ttyl1 through /dev/ttyl3 (though for some reason
/etc/ttys doesn't contain entries for the latter two).

Well, no, at this point you're in single-user mode.  To continue,
enter ^D:

login: 

I've forgotten what the standard password on root is; I fear it has
*not* been removed.  It could be 'begemot' or 'begemot1'.  To change
it, you will need to rebuild passwd, which will not work otherwise.
Do that in /usr/src/bin/passwd.  If you have trouble, I can send you a
passwd binary.
