Re: Stopped at ifnal stages of netbooting MicroVax II with NetBSD

Ok. So the lines before last night essentially gave root no permissions 
at all. So that could be a reason for the fail.
Now root and swap are accessible by root as root. usr and home are not 
really accessible by root still, but I guess that is fine.

And I assume bonzo is trying to mount /export/client/root as /

So, does it work any better now?
