Oops.
Sorry for that last mail. I had not read all your message before
sending it.
I'm not sure what is wrong..
I have successfully gone through that point in CURRENT.
I always make a new kernel, boot on it and then make world.
I updated my fstab before booting the first new kernel and my
make world and next kernel worked fine.

the easiest way is to see the output of
fdisk /dev/rwd0
if the BSD partition starts at 0
then it's dangerously dedicated.
if it starts above 0 then it's not
