John,
I fixed this in trunk. Please copy the attached file to
$OSCAR_HOME/packages/ganglia/scripts
If you need to rerun this (such that you apply the change to an image) you
should do:
cd $OSCAR_HOME/packages/ganglia
env OSCAR_PACKAGE_HOME=`pwd` scripts/post_rpm_nochroot
/var/lib/systemimager/images/$YOURIMAGENAME
Regards,
Erich
