[Ovirt-devel] [PATCH node 2/3] copy initrd0.img to root partition

A previous patch removed the manual initrd rebuild as dracut now builds it
correctly. With that being removed the initrd0.img file was not being copied
over to the system preventing boot

	I think we need to check whether the partitions are ${ROOTDRIVE}1 or
${ROOTDRIVE}p1 here.  See code around partroot and partrootbackup below

This doesn't apply to current next.  

Also, we need to ensure that we quote all variables that contain the
path to a drive like HOSTVGDRIVE and ROOTDRIVE.  This is because some
older disks and disks on vm result in wwids that contain spaces.
Some/Many of these might be fixed by the rebase since most of those were
fixed in the latest patch on next.
