Well, that is what backups are for. If you are mirroring everything but a small root, it will take less to get back up. You will only have to build a new root. You can use the extra space you would have used for the root mirror to hold an ondisk backup of root - the dump to disk would both write and restore much quicker than tape. I can guess at a few reasons that root isn't mirrored, but I don't know the official reasons. It would seem like a nice thing to be able to do, though. ////jerry > > Thanks for the insight! > Stephen Hoover > Dallas, Texas > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
