yes this is what happens with init=/bin/bash

VFS: Mounted root (jffs2 filesystem) readonly.
Mounted devfs on /dev
Freeing unused kernel memory: 56k init 4k openfirmware
Starting userspace with /bin/bash
Starting userspace with /sbin/init 
Kernel panic: No init found.  Try passing init= option to kernel.

I have booted from jffs2 one time (the first time I tried) but I had syslogd
starting in the init script and jffs2 creates data everytime something
happens that syslogd saves that creates more log ... Well I could not do much
before the disk was full so I did this steps.

erased the flash with erase /dev/mtd/0 0 128  (I have 8MB flash)

mounted /dev/mtdblock/0 on /mnt/mtd

Created the filesystem with (yes I know cp has -x option)

find / -type d -xdev -exec mkdir /mnt/mtd/{} \;
find / -type f -xdev -exec cp -dpvf {} /mnt/mtd/{} \;

It is not possible to boot from the result of this.
