This should also mean that instead of `mount /dev/mirror/gm0s1a /mnt` one would use e.g. `mount /dev/mirror/gm0a /mnt` on sparc64. I don't know though if gmirror(8) needs to be made aware of this for e.g. `gmirror label` to do the right thing or maybe already is, i.e. whether it needs further changes in order to make it work on sparc64.
