Magic? ;-) Something in the packaging of binfmt-support and/or qemu-user-static? I was just following instructions I picked up on the web. I can assure you the work because I had a disk crash a while back and did a system re-install including following these instructions to setup my ARM chroot again. (That's one of the reasons I write my own crib sheets when I do a task like this :-) -- Tixy -- To UNSUBSCRIBE, email to debian-release-requ...@lists.debian.org with a subject of "unsubscribe".
