I don't see a way to set the context of the socket that systemd listens on. If there is a way to do this please tell me otherwise I'd like to see an option (SELinuxCreateContext?) added to be able to set the context (setsockcreatecon) to be used by systemd when creating the socket. Currently as an extra layer of security I add code called in the socket activation ExecStartPre process to check that the source context (peercon) can connect to the target context (getcon). If a sockets context was set by systemd I would have to perform this additional check as my SELinux policy would do it for me.
