P.S. I did not get those errors on my terminal, though.

[root at elan /root]# rm -rf /mnt/jffs2/*

Hence Yes!

P.S. I also got some strange (debug type) messages from JFFS2 on the
terminal I
was running the program at, but NOT on the serial console (why?)
I sent those to Frederic. I don't have access to those here, but maybe
Frederic
can forward them to you. It may help decipher what is going on.
