Good idea - use raid1d instead of raid1a. I just disklabel -W raid1
(thank you Michael) and did the usual. You can get into the amusing
situation where you can't write the disklabel on cgd0 because that
would overwrite the disklabel on raid1a, yet a valid disklabel on
cgd0 is the check for a valid passphrase (ie you even get surprised
simply setting up a cgd regardless of "scrubbing")
