Subject: [PATCH] examples: add systemd socket and service files
Date: Tue, 17 Nov 2015 21:45:22 +0000	[thread overview]
Message-ID: <20151117214522.12986-1-e@80x24.org> (raw)

Since we have init scripts, we ought to have the equivalent for
systemd users who cannot upgrade via the normal SIGUSR2 mechanism;
but can use multiple services: "unicorn@1" + h"unicorn@2" to
accomplish the same thing.

Based on examples by Christos Trochalakis <yatiohi@ideopolis.gr>
