Thanks, I'll queue up something like the following patch.
Comments/corrections greatly appreciated:

From: Eric Wong <normalperson@yhbt.net>
Subject: [PATCH] doc: update documentation for systemd + PrivateTmp users
The PrivateTmp feature of systemd breaks the usage of /tmp for the
shared Unix domain socket between nginx and unicorn, so discourage the
use of /tmp in that case.
While we're at it, use consistent paths for everything and use an
obviously intended-for-user-customization "/path/to" prefix instead
of "/tmp"
