Yes, if you have your base system on zfs you have to installworld with 
the old kernel booted.

Here is what i did.

installkernel, reboot, if the kernel boots fine (zfs will obviously not 
work and show messages like "internal error: out of memory"), boot 
kernel.old, installworld, reboot. Everything should be fine.

I think this should be added to UPDATING with better wording of course 
;-). This is going to bite all users who have /, /usr, $SRCDIR or 
$OBJDIR on zfs i think.

AFAIK this will be needed for -CURRENT and for the 7.2 -> 7.3 update.
