I believe it does. I seem to remember using "dd" to put identical
partition tables + drivers on two removable cartridges, and finding that
"disklabel" groks the changed version immediately.

The more or less documented method on i386 is to use "disklabel -W"
before, and "disklabel -N" after, but that doesn't seem to be necessary
for mac68k. It wouldn't make any sense to anyhow, since disklabel's
create/edit modes are disabled.
