   Perhaps this is the same initscripts bug that was introduced with
OM2008.9, causing it to fail to boot if you upgraded from OM2008.8 with opkg
instead of installing a new image? The bug is that /etc/init.d/udev tries to
write to the rootfs before it has been remounted rw. Example patch which I
use to get OM2008 going after the upgrade:

--- /mnt/flash/etc/init.d/udev~	2008-11-24 04:20:49.000000000 +0100

(You'd get a message something like 'tar: Unable to open devices'.)

   The rootfs should always be mounted ro at first.
