Ok, I'm playing around with thin and nginx now. I am into sinatra and padrino and stuff.
So, I am creating sockets for thin so nginx can read them. I need a directory in /run
I've decided to create a directory called thin; with 2770 permissions and owner/group would be renich/nginx (for now; when done, I'll create the app's own user).
There is a standard way to do this. Just create a file:
d /run/thin 2770 renich nginx -
Now, how do I make the tmpfiles regenerate without restarting? Fairly easy:
su -c 'systemd-tmpfiles --create'
man 8 systemd-tmpfiles
