I'm wary of hardcoding the names "fs_journal_location" and
"fs_journal_size" since different journal types might have different
representations of how the journal is stored other than just "location"
and "size". A journal version might be a good idea though.
Since we've space, why not burn four "locators" now which is twice as
many as we need so we have some spares later on?
