NFS mount problems
Does anyone have a clue as to what the problem is with NFSv3 in the
installation system? Is this still a problem with more recent kernels?

Thanks a lot, Matt. I went over there and found a post from Gerhard
Tonn from October 2002, and he pointed a similar problem over on the
Marist linux390 list (see his post from the October 2002 Marist
archive at this url (watch wrapping!):

At the linux390 link, I found this advice from Stefan Gybas:

Well, I brought up the installation bootstrap system as far as
telnetting in to start the configuration, then telentted into a
second session. The "mount" suggested by Stefan worked!
However, that syntax results in an RW mount to an RO source, so I
tried this syntax instead:
mount -o ro,nolock,nfsvers=2 server:/mnt/cdrom /instmnt
And this also worked fine, I could read files from the DVD mounted
at the RH base system's /mnt/cdrom device (which is really a DVD ROM
drive) from the 2nd telnet into the installation bootstrap system.
Then I tried it with the configuration dialogs, and this response to
the NFS option's request for the nfs mount point also worked:
-o ro,nolock,nfsvers=2 server:/mnt/cdrom
So, I am off and running with an install from the DVD of Debian-390.
I will report back when I'm done with the install and let everyone
know how it works. I am wary of using nolock, though I suppose it
won't hurt in my single-system setup. I will also try it without
the nolock option and see if that makes a difference.
When I'm done with this install (and a few testing upgrades I need
to make to work on a project I'm on), I'll post a mini-HOWTO to the
files section here for those who want to try it.
More as it happens.
