Talk:Modifying the root image
The roots.jffs2 for the n900 cannot be mounted this way: file doesn't recognize it as a jffs2 filesystem and trying to mounting it floods syslog with these messages:

Maybe it's encrypted?
Nope, it's just a different filesystem (UBIFS).
Well, they shouldn't call it jffs2 then, anyway see this tmo thread:
