That is suboptimal for me since I'd still have to manually mirror the /boot partition (dd) every time I updated the kernel. Not a huge problem but not quite what I want to do. The way I tested this was take a second drive, disklabeled it accordingly: disklabel ad2s1 to create an 'a' partition ccdconfig ccd0 128 none /dev/ad2s1a disklabel -w ccd0c auto newfs /dev/ccd0c cp / to ccd0c Thus there's a one-drive ccd partition. I added boot blocks and attempted to boot it but got a "not ufs" error. The ccd partition format is different from a normal ufs partition. My question was "how different?" and "how much work to have the boot blocks find the right offset to the fs?" ccdconfig is on /sbin so post kernel load should have worked fine. -Nate To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
