I do have them mounted as soft.  An example entry is:

puff:/usr/export/home/amiga   /puff/amiga   nfs bg,rw,soft,retry=2 0 0

unfortunately, if I try to shutdown the system or do a umount, it just hangs
there.  I get status messages every minute or so saying that the server isn't
responding.  It's been suggested that I do a 'umount -k <dir>' for each
of the remote NFS partitions.  I've not had the time yet to try this though.
At the time I did the umount, there were no processes with open files in the
remote system or with current directories there so I don't know if this will
do any good or not.

If when I boot up the server isn't there, then the umount works just find and
goes into the background trying to mount.  Just can't get umount to give up
and quit.
