Actually, isn't this dangerous, since you would be booting a new kernel with an old world, which could cause problems if there are significant changes to the kernel that breaks the old world? What I usually do is: make buildworld make buildkernel KERNCONF=xxxx shutdown +15 "Upgrading the World. Be right back." <backup /etc, the old kernel, anything else that's critical> make installkernel KERNCONF=xxxx mergemaster make installworld shutdown -r now This way, the running kernel always matches the installed world until that final "shutdown -r now" command. At worst, if the new world completely breaks everything, even your ability to reboot, you can just hit the reset switch and hope everything was written to disk first. -- Richard Glidden richard@glidden.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
