Hello. As I posted http://www.turnkeylinux.org/docs/tklpatch/development#comment-1296 My patch conf looks like this :

#!/bin/bash -ex

HOSTNAME=somehost
# set hostname
echo "$HOSTNAME" > /etc/hostname
sed -i "s|127.0.1.1 \(.*\)|127.0.1.1 $HOSTNAME|" /etc/hosts
 

I have nothing in deb/ or overlay/

As I mentioned the result is iso that is loading busybox shell. couldn't see any errors on the kernel boot messages.

One thing I should mention is that I'm running the tklpatch from other distro and not ubuntu. don't know if that matters.

Any hints ?
