That is to  late. Once the PE address is configured, sysctl does only 
avoid to learn/generate the next one. It does not delete the first 
PE-adress. Of course the static address should be preferred, but this is 
not the case.

systemd is also new for me. At the moment I use the compatibility-script 
  /etc/init.d/boot.local for correct/reloading some things, but this ugly.
