[Bug 117957] Re: Need to modprobe nfs module before mounting nfs4 export

[Stefan Bader]

This is now worked around in Precise (12.04) by always starting idmapd
(because mount does negotiate an nfs4 mount anyway, even when fstype is
nfs) and having a modprobe for nfs in the startup script. So after
installing nfs-common, the nfs module is practically always present (see
bug #662711). Therefor marking this as fix released for trunk.

Bug description:
  In order to mount an nfs4 export, it is necessary to modprobe the nfs
  module manually, unless an nfs mount has already taken place.

  $ sudo mount -t nfs4 router:/ /mnt
  mount: unknown filesystem type 'nfs4'
  $ sudo modprobe nfs
  $ sudo mount -t nfs4 router:/ /mnt

  This effects gutsy (original report), hardy, intrepid and jaunty.
