rcolistete, I'm running xephwm as root, from debian-m5-v3e.img.ext2. I only added -fullscreen and deleted +kb for some reason , the rest was there 'out-of-the-box'. It's not as if I knew enough about Xephyr and xinit to add something like parent windows

Also another thing: can I use an image built by debootstrap with these scripts? (archived, with a FS etc.)
