* The script needs to run with root permissions in order to
do the ipset operations. So remove code to drop the permissions
on startup.
* Adjust execute calls to use the proper functions from
general functions.
* Add some code to set the correct ownership (nobody:nobody) for
changed files during script runtime.
Fixes#13072.
