here it is:

Obviously, in recent busyboxes, sourcing a non-existent file makes busybox
(silently?) exit, which in case of scripts/live leads to an immediate kernel
panic since the root fs is not yet mounted.

Wrapping the "./tmp/net-${device}.conf" into a

                if [ -e "/tmp/net-${device}.conf" ]; then
                  . /tmp/net-${device}.conf
                fi

in scripts/live solved the issue for me.

I tried remastering grml64-small_testing_20120528.iso using Debian sid with
grml-live 0.19.5 and 0.19.3, resulting in an ISO that also kernel panics on
network boot. The original daily iso works fine.

Here is my grml-live command line:

sudo grml-live -V -e ../grml64-small_testing_20120528.iso -s wheezy -c
DEBORPHAN,GRMLBASE,RELEASE,AMD64,IGNORE -r "Zugschlus" -g grml64-zg -o
~/grml-zg/ -v 20120712

Ok.

Booting current grml64-small from the network fails with a kernel panic. serial
console output from a KVM VM is attached as daily.bootlog.

My ipxe config file is:
#!ipxe

kernel http://192.168.19.254/boot/vmlinuz
fetch=http://192.168.19.254/boot/grml64-small.squashfs quiet boot=live lang=us
nomce apm=power-off noprompt noeject vga=791 debug=1 serial console=ttyS0,57600n8
initrd http://192.168.19.254/boot/initrd.img
boot

The last .iso that works fine with network boot is
grml64-small_testing_20120528.iso. Starting with
grml64-small_testing_20120612.iso, the kernel panic shows itself. This includes
http://daily.grml.org/grml64-small_testing/2012-07-06_05-31-17/grml64-small_testing_20120706.iso.

For some reasons, all but the first line is eaten by something.
