How will the enforcer on the backup server know which are the currently
used keys? E.g. how many key rollovers were done meanwhile?
We have the signer running on both servers, but the enforcer only runs
on the main server. And the output files of the enforcer are rsynced to
the backup server. When the backup becomes the master, we start the
enforcer on the backup server and switch the rsync direction.
