Also, don't edit any Maemo scripts to mount Ed partition... ED chroot will mount everything for You when needed. Also, mount point /.debian/ is created automatically during ED installation.

All you have to do, is to mount Your newly created partition (You can do it even from Gpared liveCD, it doesn't need to be done from within Maemo itself), mount Your image via loopback command, and copy Ed content.

On ED thread, eight wrote step-by-step instruction about mounting and copying if You have partition created already - check it for instructions.
