So, in my anonymous ftp heirarchy, I have a stub copy of /etc/passwd for
~ftp/bin/ls to make use of.  It turns out that it *doesn't make use of it,
however, because the passwd routines demand to have a DBM database
available.  pwd_mkdb doesn't appear to have an option for building a
database anywhere except the live location.

Is there some way of setting this up that I just haven't seen yet, or
is it time to fiddle with pwd_mkdb?
