I thought I would stir the waters again and ask how this new feature seems to be working out in -current. Is there much chance of it working with the 4.x-branch of releases? I realize there's a lot of work here, and that it may very well need to be tied into some of the smp-related work in 5.0 (wrt big-locks, etc), so I won't mind if it can't make it any sooner. Mainly I just wanted to reiterate that this sounds like a very cool feature (particularly given how huge disks are getting, a snapshot facility seems like a good use of that spare space), and that I'm looking forward to it whenever it does appear. -- Garance Alistair Drosehn = gad@eclipse.acs.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-arch" in the body of the message
