[lug] question about dd

[David Trowbridge]

This is fiarly simple, but there are a couple issues I'd like to raise:
first, the command to do this is:
dd if=/dev/hd<n> of=file

The problems with this is that it will copy everything - partition tables,
disk sizes, etc, so if you use your image to write a drive that is not
exactly the same size, it will not fill up the disk completely, and may
not even work at all.
