Hm, not sure about the devfs thing, sure seems like it would not be
related, but... I must admit that I have not yet really looked into this
one.

Ack!  Nice catch, I guess we should fix that up, didn't think to look
for ext2-specific things in the initscripts... one more for the eventual

I think that's because of the "-n" option, it doesn't write to mtab, so
"mount" won't show you the (ro) even though it is.
