You seem to remember incorrectly.


minbar:root:~:1 # share
-               /   root=@10.24.32.10/32,rw=@10.24.32.10/32   "minbar root"
-               /home   root=@10.24.32.10/32,rw=@10.24.32.10/32
"minbar home"
-               /export   root=@10.24.32.0/24,rw=@10.24.32.0/23   "exports"


While this may seem an odd thing to do, looking at my mounts there was
meaning in my madness:


babylon5:alaric:~:3 $ cat /etc/fstab
[...]

### remote filesystems
minbar:/                /mnt/minbar             nfs
ro,rsize=16384,wsize=16384,hard,intr,suid,nfsvers=3,tcp 0       0
minbar:/home            /mnt/minbar/home        nfs
rw,rsize=16384,wsize=16384,hard,intr,suid,nfsvers=3,tcp 0       0
minbar:/export          /minbar                 nfs
rw,rsize=16384,wsize=16384,hard,intr,suid,nfsvers=3,tcp 0       0


Notice it's set up this way so that I can have minbar:/ mounted ro, but
minbar:/home mounted rw.


(Notes:  minbar runs Solaris 9, babylon5 runs a custom Linux install
based long ago on Slackware 7 but no longer really recognizable as such.)
