Trying to get Linux Live from Linux-Live.org work

echo “Now press Enter…”
read junk

I’m confused from the very beginning.  Why do we need to

CHANGEDIR=$(dirname $(readlink -f $0))
echo “Changing current directory to $CHANGEDIR”
cd $CHANGEDIR

The script ends up erroring at

echo “Using kernel modules from $ROOT/$LMK”

I’ll have to look for a good wordpress module for code where there are line numbers…
