/* 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.
