+            /* WARNING - nasty hack!
+               Settings for the lock screen are not available to the crypto
+               screen (CryptKeeper) at boot. We duplicate the ones that
+               CryptKeeper needs to the crypto key/value store when they are
+               modified (see LockPatternUtils).
+               However, prior to encryption, the crypto key/value store is not
+               persisted across reboots, thus modified settings are lost to
+               CryptKeeper.
+               In order to make sure CryptKeeper had the correct settings after
+               first encrypting, we thus need to rewrite them, which ensures the
+               crypto key/value store is up to date. On encryption, this store
+               is then persisted, and the settings will be there on future
+               reboots.
