This is totally evil and a huge waste of disk if the old disk is
a 4 GB and the new disk is a 40GB. Not to mention Linux may complain
that the disk says it is a 40GB drive and the partition info says it is
a 4GB drive.

So cheap means it's ok to waste? Sheesh how I hate that mentality.
Kind of reminds me of the thought patterns of a certain West Cost
software company. ;)

Why not just ghost it?
Or ghost4unix?

Of course g4u has similar problems that the above cat command does.
You will have to go in and create partitions of the leftover space
from a smaller disk to a larger disk. ;)

Hope this helps,
