[Bug 668429] Re: mount.cifs is not included in initramfs, so netboot=cifs doesn't work

[maxim]

It seems something more is needed in order to get it to work properly.
Performing the following results in initramfs saying this when
attempting to mount the root file system:

mount error: cifs filesystem not supported by the system
mount error(19): No such device
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
nfsmount: need a server
nfsmount: need a server
nfsmount: need a server
...

To get mount.cifs into the initrd, first you must have install
mount.cifs

To do this run:
# sudo apt-get install smbfs

Found some instructions here:
https://help.ubuntu.com/community/LiveCDCustomization

# mkdir lztempdir
# cd lztempdir
# lzma -dc -S .lz ../initrd.lz | cpio -imvd --no-absolute-filenames

Then do:

# cp `which mount.cifs` sbin/mount.cifs

Then pack it back up:

# find . | cpio --quiet --dereference -o -H newc | lzma -7 >
../initrd.cifs.lz
