Also, while the cautious approach detailed in /usr/src/UPDATING is never wrong, much of the time you can do the upgrade perfectly well by installing world+kernel together and just rebooting once. Obviously this is not a good idea if your machines are in a datacenter many miles away and you don't have console-equivalent access or if you're upgrading over a large delta in versions, or you're making major changes to the kernel config. This sort of operation is something that ZFS boot environment support (recently committed to HEAD, due for MFC within the month) makes much, much safer and easier to deal with. You don't need to do a separate reboot to test the kernel as you've still got an entire kernel+world in the previous BE to fall back on. Cheers, Matthew -- Dr Matthew J Seaman MA, D.Phil.
