How does one mount an existing jffs2 partition so it is writeable?

Yeah -- you're probably right. That's the reason I refused to do the 
automatic unlock when it was originally suggested. We are fairly good about 
aborting a mount attempt if it really doesn't look like a JFFS2 partition, 
but if you have the partitioning wrong so that the range we try to mount 
includes some JFFS2 _and_ something important, that's still going to break.
