I want the bikeshed green with black polkadots! =:^)

More seriously, ro-noreplay ?

As Hugo says, norecovery clashes with the recovery option we already 
have, so unless we _really_ want to maintain cross-filesystem mount 
option compatibility, that's not going to work.

I'm not sure we want to encourage thinking of it as a log, since it's not 
a log in the journalling-filesystem sense but much more limited.

And I think ro needs to be in there for clarity.

hard-ro strikes my fancy as well, but ro-noreplay seems clearer to me.
