Let's make this an excercise in dogfooding: let's turn on more security features for all our long-running services. Specifically: - Turn on RestrictRealtime=yes for all of them - Turn on ProtectKernelTunables=yes and ProtectControlGroups=yes for most of them - Turn on RestrictAddressFamilies= for all of them, but different sets of address families for each Also, always order settings in the unit files, that the various sandboxing features are close together. Add a couple of missing, older settings for a numbre of unit files. Note that this change turns off AF_INET/AF_INET6 from udevd, thus effectively turning of networking from udev rule commands. Since this might break stuff (that is already broken I'd argue) this is documented in NEWS.
