NO!  This won't do what you think it will.

Sugggest instead:
	if /dev/sdaX and /dev/sdbX are the same size:
	then dd if=/dev/sdaX of=/dev/sdbX 
	else mkfs /dev/sdbX
	     fsck /dev/sdbX
	     mount /dev/sdbX /mnt/tmp
	     cd $MOUNTPOINT_FOR_sdaX
	     find . -mount -print | cpio -pdumva /mnt/tmp
             umount /mnt/tmp
	     fsck /dev/sdbX
        fi

Caveat:  Neither /dev/sdaX nor /dev/sdbX should be mounted if you're gonna
use dd(1) for the copy.

Oh yeah... make a boot floppy, too ;-)
