Thanks for the heads-up! I was just about to update a couple of sparc64
machines here. Fortunately, the only ZFS file systems there are external
file systems (no /, /usr, /var etc...), so it's gonna be painless, I suppose.
But what about other layouts? Does it mean that an installkernel, reboot,
and installworld won't work?
