Since we don't understand it, allowing a R/W mount is dangerous. You can read more about this using the cvsweb to check the commit logs for the ext2fs files. This was bde's (Bruce Evans) changes. I can see the point in wanting to force a R/W mount, on the grounds that you know more about your setup than the software does (which is the whole point of the software denying you R/W access in the first place :), but you'll need to convince Bruce, not me, of that. Convincing Bruce is easy, as long as he agrees with you to begin with. If he doesn't... -- Daniel C.
