Your problem raises another interesting problem.  Takea look at the
bottom of rc.diskless2, where /dev is mounted in mfs.  That operation
needs to be conditionalized on the presence of DEFVS.

What we really need is for someone who runs a diskless environment to
try placing the call to rc.devfs immediately before the call to
rc.diskless1 and to apply something like the following patch to
rc.diskless2:

Feedback from such a person would be most useful, I think.

Ciao,
Sheldon.
