For the past couple of months, systemd has been emitting some warning messages on my systems that have Stork package enabled. They look like this:

Jun 07 08:49:49 stork22 systemd[1]: Configuration file /lib/systemd/system/isc-stork-server.service is marked world-writable. Please remove world writability permission bits. Proceeding anyway.
