There was a discussion about this the other day.  Someone reminded us
all that, by design, you can't change the slices and partitions on the
system disk.  You could do it by booting from Freesbie, or I believe
there is a flag you can turn off in single-user mode.  Check the
mailing-list archives for the last couple of months.
