OK.  No problem.

By the way, you can't run bsdlabel on a mounted and active slice.
So, if you are booted to da0s1, then it won't work.   You will need
to do something like boot to the fixit CD or boot from another disk 
(which will change your device name for that moment).

Yes, you can do it both with file and edit method.  You only need to
specify the offset for the first slice and then * after that for offset.
Then size for every one except the last which can also be * - and it
will put everything left in to that last one.

It works just dandy for me that way.
