A note about socket files not to be placed in /tmp

[gamboz]

I've lost some time configuring apache-uwsgi interaction via unix domain sockets because I had the socket created by uwsgi in /tmp, but apache did not see it because it was launched by systemd with PrivateTemp=true.

So I'm proposing to add a note for who might have the same issue.

Ideally, under systemd you'd just use a systemd managed .socket
https://www.freedesktop.org/software/systemd/man/systemd.socket.html

that way you don't need to bother with setting up permissions to the socket and the uwsgi service and the nginx service.

@gdamjan yes. My point was only to remind ignorant people (like me) about this systemd behavior :)
