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

[Nigel Johnson <nw.johnson%ieee.org@localhost>]

I went and set up /etc/exports using yast, thinking that maybe there was
some SuSE-specific magic that was needed, and it now doesn't throw out
my changes and substitute something else!

It is still getting to the point where it tries to mount root after
downloading and panicking with getaddr fail

Should I be worried that there are more than one entry for mountd and nfs?

T540p:/ # showmount -e
