Here's the reason: Running kernel and world out of sync can potentially cause all sorts of problems (and usually does). The buildworld, buildkernel, installkernel, reboot, installworld sequence is designed to specifically reduce the chances of getting you into a corner you can't back out of. For example: make buildworld make buildkernel < anywhere before this point, if you have problems or change your mind, you just delete /usr/obj and everything is back to normal make installkernel < After this point, reverting consists of copying kernel.old back to kernel and /modules.old back to /modules reboot into single user mode < if the new kernel doesn't boot, you can boot kernel.old and follow the steps above to get things back to where they were make installworld < If you got this far ... chances are everything went well and you'll have no reason to revert. > At this point, it won't complete the kernel build and is > showing signs of being unusable (e.g. "ipfw show" just > dumps core). Is it too late to correct this or is a > reinstall and reconfigure next week the only option left? I would suggest recvsupping to RELENG_5_0 and try the buildworld, buildkernel again ... if they both succeed, continue with the installkernel, reboot, installworld process and you should be back to a fully functioning 5.0 system I actually had to do this once, and it worked. From there, you should be able to do the 5.0 -> 5.1 upgrade process again. Even better, if you know the exact date of the sources used to build the kernel that's currently running, you can use the date keyword to cvsup sources to exactly that date. That would be even safer: *default release=cvs date=2003.03.23.10.00.00 -- Bill Moran Potential Technologies http://www.potentialtech.com
