This is telling you that this file system has features (put in the by a
recent version of Linux, most likely) which our ext2fs code does not
understand. 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...
