As far as I know you won't need jffs2 (or any other fs for flash
memory). It is meant to be used on embedded devices that directly access
the flash memory. In your case, the CF-disk takes care of wear leveling.
Just use ext2. However, you could still get problems because, as far as
I know, wear leveling needs to be tuned for the FS and most probably no
one tuned the CF-disk for ext2. Maybe you could use fat instead...
