Powering up/down for SCSI devices on the fly is generally a sure way to hang the buses, screw the disks etc. It *should* work, but my experience shows that it has something like a 20% chance to bomb. The above remark does not mean your point about devfs is invalid, I'm just not thrilled by the example ;-) Wilko _ __________________________________________________________________________ | / o / / _ Wilko Bulte email: wilko@yedi.iaf.nl |/|/ / / /( (_) Private FreeBSD site - Arnhem - The Netherlands --------------------------------------------------------------------------------
