[BBLISA] Does read only really mean it?

[Matt Simmons]

My knowledge is somewhat limited to the Linux world, but in my experience
I've never seen a mount be set to 'ro' and have anything updated. I hate to
use the term 'flabbergasted', but I'm pretty sure that if I saw an
implementation that didn't respect the 'ro' flag, I'd be at the very least
'put out', and perhaps even vitriolic.
