	My e2dis suite, which I hopeful to release soon, will probably
	be a better fit for such image-level backups.  Namely, it'd
	allow one to identify the free blocks on an Ext2+ FS and only
	copy the rest.

	I'd second that using rsync(1) instead of cp(1) when copying to
	flash media is a good idea, as it reduces both wear and the time
	necessary to make a copy.
