I think the problem is that your new disklabel will move BOTH the a and
the c partitions, so the partition which was opened for modification will
move.

I think the thing to do is look at what the disklabel will set say the a
partition to, manually edit the disklabel on the other partition (c here)
which can change the disklabel making a be what it will eventually be.
_Then_ do the full disklabel write on the partition you just changed above
(a here). It won't be changing this time.

Take care,
