NetBSD will protect the disklabel area of the disk until you run
Solaris protects the label in a different way -- it transparently
skips over the label area when creating file systems and using swap.
You're free to mangle the label area however you want.
I did it recently when I dd'd the sparc64 miniroot to the swap
partition, not realizing the Solaris install had put swap at the start
of the disk.
