Bug Description

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.

Tested and it works.

Detailed Steps:

1. booting system with current stock 12.04.3 image on usb
2. and enable -proposed in software-center-properties then apt-get udpate
3. apt-get install initramfs-tools
4. mkinitramfs -c lzma -o /tmp/initrd.lz `uname -r`
5. unlzma -c -S .lz /tmp/initrd.lz| cpio -t | grep nfs
6. verified that nfs3 and nfs4 are both in initrd.lz

This bug fix is not found in the milestone ubuntu-12.04.4.
Shouldn't it be included for 12.04.4 so that the CDs will be able to boot from NFS?

Or maybe it's automatically included as the initramfs package has been released to -updates?
Just want to make sure that the 12.04.4 CD is tested for this fix and will actually boot from NFS.
