(I have a 32-gig disk with a bunch of 2-gig virtual-disks on it. With that many systems, it's much easier for me to deal with files than a whole bunch of "small" partitions on the raw disk). The patch from Ian sounds like it would be interesting for me. I'll have to try that. It would be great if I could get back to regularly running an up-to-date current. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
