As I say, I have never tried to modify partitions on the root/boot
disk currently being used. I suspect that, since the root partition
of that disk is mounted, you will not be able to write in the label
even for other not-currently mounted partitions on that disk.
You may have to boot from some other device, either another disk
or a live CD or fixit floppy in order to work on that particular
Maybe someone else on the list knows for sure.j
