Hi Dieter,

Here are my patches:

1/ Modified automated_script

. /etc/archiso/functions

automated_script ()
    script="$(cmdline_param script)"
    if [ -n $script ] ; then
        stat_busy "Configuring $script"
        if [[ $script =~ ^http:// || $script =~ ^ftp:// ]] ; then
            wget "$script" -q -O /tmp/startup_script >/dev/null
            cp $script /tmp/startup_script
        if [ $rt -eq 0 ] ; then
            chmod +x /tmp/startup_script
            echo "/tmp/startup_script" >> /root/.bash_profile

add_hook multi_end automated_script

2/ Modified inittab

c1:2345:respawn:/sbin/agetty -n -l /usr/bin/autologin -8 38400 tty1 linux

3/ New /usr/bin/autologin

/bin/login -f root

I tested successfully everyting (through PXE) with the following scripts:

aif -p interactive

And also (for automatic install, this procedure needs a web server, I wrote 
something for that purpose and will publish it):

mac=$(ifconfig eth0 | sed -n 's/.*HWaddr \([a-zA-Z0-9:]*\).*/\1/p')
wget "$mac" -q -O /tmp/aif_profile >/dev/null
aif -p automatic -c /tmp/aif_profile
wget "$mac" -q -O - >/dev/null

The MOTD get displayed in both cases.

BTW, something changed in archlinux-2011.02.01-core-x86_64.iso; archiso-pxe-
server is working with archlinux-2011.01.09-core-x86_64.iso but not with the 
newer 2011.02.01 version (nbd-server problem).
