Hello, I try to port systemd to a live distro. The biggest problem is that they work with modules. So before the start up can be processed all the modules needs to be packed out and copied to memory. The script for that is this : #!/bin/bash# Activate a module, while running LiveCD.# Include it into live directory structure on the fly## Author: Tomas M. <http://www.linux-live.org># Modifications for Porteus by fanthom/brokenman MODULE=$(readlink -f "$1") # Make sure that only one (two for root) instance of 'activate' script is runningpid=`ps a | egrep -v 'grep|xterm' | grep -c -w /opt/porteus-scripts/activate`while [ $pid -gt 3 ]; do echo "too many activations - sleeping 1 sec..." && sleep 1 pid=`ps a | egrep -v 'grep|xterm' | grep -c -w /opt/porteus-scripts/activate`done # Switch to rootif [ "$DISPLAY" ]; then if [ `whoami` != "root" ]; then xterm -T "Please enter root's password below" -e su -c "/opt/porteus-scripts/xactivate $MODULE && sleep 2" exit fielse if [ `whoami` != "root" ]; then echo "Please enter root's password below" su -c "/opt/porteus-scripts/activate $MODULE" exit fifi if [ "$2" = "-k" ]; then CALLED_BY_GUI_HELPER=1fi if [ -e /opt/porteus-scripts/xactivate -a "$DISPLAY" -a !
