nfs mount hangs if nfs subsystem isn't installed

[beej]

Binary package hint: mount

DISTRIB_RELEASE=6.10
mount 2.12r-11ubuntu

this machine didn't have the NFS-related packages installed. i added the following to my /etc/fstab:
host:/Volumes/G-Force/path /production nfs nfsvers=3,rsize=8192,wsize=8192,soft 0 0

when i then did:
root@ugrid4:~# mount /production/
that shell was stuck. ctl-c and ctl-z weren't able to interrupt mount

from a different shell, killall mount didn't work. i had to killall -9 mount.

once i did this:
root@ugrid4:~# apt-get install nfs-common

The following NEW packages will be installed:

i was able to succussfully run mount /production.

Fixed in 2.13 (by moving all nfs support to nfs-common - you now get a failure message if that is not installed.)
