* Artem Koutchine <matrix@ipform.ru> [20010128 17:27]: writing on the subject 'Re:' Artem> I wonder why no just try: Artem> Artem> cat /dev/ad0 > /dev/ad1 ? Would this work with disks of different sizes (of course I am looking at ad1 being larger than ad0)? And would it write the slices to ad1 as well? ;-) I'm a bit daft here but it gives me some reason to smile all the way home this evening if life can be that easy moving my system to a larger(another) disk.
