Some additional info:
I use the mtd stuff from mtd-snapshot-20050524.tar.bz2 with a 2.6.11
kernel. I executed patchkernel.sh from the mtd package.
I created a jffs2 image with
mkfs.jffs2 -e 16384 -qnd my_rootfs -o jffs2.img
Then I flashed the image with nand write.jffs2 (or from linux with
nandwrite).
A "ls" shows me the contents of the image as expected.

Then I boot linux and mount my jffs2 partiton. I deleted the uImage from
it. A "ls" from linux shows me that it is deleted.
Then I rebooted and did a "ls" from u-boot.

The uImage is still there. And "bin, dev, etc, initrd, lib" are listed
twice.
Then I deleted the "www directory" and the ls of u-boot gives me
