in /etc/profile:
export CVSROOT /mnt/punk/home/Master
in /etc/fstab:
punk:/ /mnt/punk nfs defaults
also, after initial boot with above in place, logged in as root.
cd /home
ln -s /mnt/punk/home/Master Master
cvs/rcs works just fine.
umount punk:/
or
umount /mnt/punk
just creates core in current working directory and does not unmount the nfs
locally.
all other local umount /dev/xxxxxx do the unmount correctly.
