Why the 0? I did this (Thanks, Doc!)

Right. I know what to do once I'm in. The only thing that threw me
about Digital Unix vs other stuff I've used is that if you _don't_
use vipw to edit the passwd file, you have to manually run mkpasswd
to update the hashed password file (I'm used to a shadow file, or,
for older stuff, _just_ the /etc/passwd file and nothing else).

In my experience, if you intend to go from single-user mode to
multi-user (i.e., you don't reboot from single-user), it's
safest to not leave anything mounted that isn't mounted when
you got your prompt. I'm not saying this is the case for Digital
Unix, but for older BSDish stuff I used in the past, if you,
say, mounted /usr/home while in single user mode, then ^D to
exit your shell and allow the system to start up, but haven't
unmounted /usr/home first, the startup scripts complain about
a busy mount point or some other complaint. I always leave the
system the way I found it, which is / mounted read-only, everything
else unmounted. What you suggest might work these days, but I
cut my teeth on 4.0BSD and Ultrix 1.1. This is just my first
experience with Digital Unix on an Alpha.
Still curious about the "0" in your sample line, though.
Thanks for the tip,
