initscript mentions using /etc/sysconfig/trafficserver, but doesn't use it

The initscript says:

1. Fedora:
2. When this file is installed as /etc/rc.d/init.d/trafficserver
3. and added to the chkconfig system with `chkconfig --add trafficserver`
4. then the default values of these variables can be overridden
5. in the /etc/sysconfig/trafficserver file

but doesn't source /etc/sysconfig/trafficserver as it indicate it should. It needs to source this file.
