The traditional way of doing this is to use a 'reboot' command. Unfortunately it seems that the reboot functionality doesn't survive during a upgrade and instead the operator is rewarded with a 'dumped core' instead. This isn't usually a problem if the server is in the physical locality of the operator, but is a 'right royal pain in the arse' if the server is located on a remote desert island ;) >How-To-Repeat: Start with a 2.2.X machine. Cvsup the source tree to 3.2-RELEASE, or 3.2-STABLE. Make upgrade (or aout-to-elf-build, install, move, etc) Use mergemaster to rebuild the /etc/ config, etc. Rebuild the kernel and install. Disklabel -B primarydrive - to install new boot blocks for elf kernel. Reboot --- bus error! Network is down. Machine sits happily in single user mode. >Fix: Try and find someone who's near your remote server and ask them to press the reset button. Server then boots normally and arrive in 3.2 mode perfectly happily. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
