Description David Strauss 2014-02-19 08:03:42 UTC 
Restart should, generally, do the same thing as stop+start, but it doesn't for sockets. This is for systemd v208, but I don't think anything in master would have substantially changed this particular behavior.

Comment 1 David Strauss 2014-02-19 08:04:26 UTC 
To be more explicit without requiring a reading of my console logs, restart also starts the corresponding service, not just the socket.
