And they also have other optimizations (partial dumps, dumps to RAM) which make dumping fast. BTW, dumping to RAM is so God Damned cool.. we should do it too -- what platforms have memory which is persistant across reboots besides alpha? Between partial dumps, dumping to RAM, and compression, my XP1000 at work will dump in about 5 seconds for a 512 MB machine. I almost don't mind crashing it because its so cool to watch it dump in a few seconds ;) Drew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
