What does openrc do when the script fails?  Just shut down the system anyway?

If you're going to shut down the system anyway then I'd just force the
read-only mount even if it is in use.  That will cause less risk of
data loss than leaving it read-write.

Of course, it would be better still to kill anything that could
potentially be writing to it.
