opkg update && opkg install blockd mount-utils
mount -t ext4 /dev/mobile-disk/overload /overlay
This problem is caused by
If your mount configuration is written in
/etc/config/fstab will be use
/sbin/block mount disk.
but in my testing
/sbin/block not Overlay mount/overlay
Hope to fix this problem
I'm testing this all out with mdadm + LVM but it seems that rc.d always takes over and runs first. My System Log says that it cannot find the UUID for my LVM for extroot and later on I see My VolumeGroup. Also for mdadm... it starts and stops, it's called twice in rc.d.
Anyone an idea about that ?
