Anyway, hard lesson learned. I wonder how Ubuntu does their live CD
install. openSUSE is introducing one too, hopefully for their users
the same bug does not occur.
Pretty much every live cd does a dd afaik.
ubuntu 7.04 keeps their rootfs natively on squashfs (versus fedora which keeps
it natively on an ext3 image which lives on a squashfs).
Therefore they can't be doing a dd for the install.
The reason for the difference is because ubuntu uses unionfs for copy-on-write,
whereas fedora uses devicemapper-snapshot for copy-on-write.
