[Bug 1217041] [NEW] initramfs-tools: please include separated nfs modules

[Ryan Tandy]

Public bug reported:

In newer kernels (>= 3.6) the nfs modules were split up and we have to
include nfsv3, nfsv4, and nfs_acl now. This was already fixed in raring
in initramfs-tools 0.103ubuntu0.3, but precise with lts-raring kernel is
still affected.

Marking those modules for inclusion even on older kernels where they
don't exist seems to be safe. initramfs-tools doesn't complain.

[Impact]

We have to manually configure the initramfs to include nfsv3/nfsv4
modules before we can boot from NFS.

It is not possible to boot the 12.04.3 LiveCD from NFS (regression
compared to .0/.1/.2).

[Test Case]

With linux-image-generic-lts-raring installed, list the contents of the
initramfs and check for nfs related modules:

gunzip -c /boot/initrd.img-3.8.0-* | cpio -t | grep nfs

nfsv3.ko and nfsv4.ko should both be present.

[Regression Potential]

Minimal. The change adds three extra modules to the initramfs, and they
are ignored on kernels that don't have them.

** Affects: initramfs-tools (Ubuntu)
     Importance: Undecided
         Status: New
