As far as read-only-database goes it doesn't see to work,
so I have submitted it to the Zope Collector.

I found that setting read-only to true in the filestorage
group in the zodb_db declaration did do the job.
A warning to anybody that want to use this is that some
third-party products do write to the ZODB at start up
which will halt the start up if the read-only flag is set.
(For instance PlacelessTranslationService and Formulator.)

<zodb_db main>
     # Main FileStorage database
     <filestorage>
       path $INSTANCE/var/Data.fs
       read-only True
     </filestorage>
     mount-point /
</zodb_db>
