Yes, for bigger filesystems it can work. It basically depends on the offset
of the data blocks in the partition. If the block numbers are low grubs works,
if they are high grubs loads garbage. On a fresh filesystem the
new files are likely to end up at the beggining of the partition
(especially if the directory tree isn't too depth). After some use you
copy a new xen.gz, it gets a high inode number and high blocks numbers, and
can't be loaded.
