/sbin/eraseall /dev/mtd8
mkdir /flash/opt2
# Mount the file system
mount -t jffs2 /dev/mtdblock4 /flash/opt2

# and use it.
# I've transfered all the X stuff to the new jffs2 partition and mount it instead of the X11R6 directory of the cramfs root
mount -t jffs2 /dev/mtdblock4 /usr/X11R6

More infos about partitions
http://agendawiki.com/cgi-bin/aw.pl?FlashDiskPartitions
and about starting for maintanance via minicom
http://agendawiki.com/cgi-bin/aw.pl?BootingForMaintanance

I recommend the following procedure
- flashing of kernel
- flashing of root
- start via minicom
$linux console=ttyS0,115200 1
# I use bash
bash
# starting rc.sysinit
/etc/rc.d/rc.sysinit
# maybe increasing the printk logging level helps before starting
echo 10 > /proc/sys/kernel/printk
cat /proc/kmsg &


TODO:
- I think it's a starting point but jffs2 for agenda has to be checked for stability
