I have tried it both with and without a -K/-k keyfile specified and with
and without a passphrase (-P/-p). Any combination results in the same
"geli: Wrong key for mmcsd0s3."
For the sake of thoroughness I have even tried it with no PKCS#5v2
iterations and with a NULL ealgo.
Each attempt writes a master key to the device metadata, but subsequent
attempts to attach the device fail with a wrong key.
