[Bug 1216853] Re: During PXE booting failed to mount nfs directory

[Daniel Manrique]

Hi, so in order to confirm my theory, I built an initrd with the missing
modules. To do this, I simply booted my live usb cd, then edited /etc
/initramfs-tools/modules to explicitly list the nfsv{1,2,3,4} and
nfs_layout_nfsv41_files modules. Then I did:

mkinitramfs -c lzma -o /tmp/initrd.lz `uname -r`

I took the resulting initrd.lz, placed it in place of the original one
on my pxeboot server, then rebooted my test installation system.

This time it was able to NFS mount the needed directories and completed
the 12.04.3 installation flawlessly.

I don't know where to express this in the mechanism that builds the
Ubuntu CD images (and even if I knew, I don't have access to modify
that). So at this point I'm hoping that this work proves useful to
someone with the required privileges to make these changes.

Thanks!
