From 058c3ffb7105a3303c3aeebfc9bf410356970e64 Mon Sep 17 00:00:00 2001
From: Steve Kemp <steve@steve.org.uk>
Date: Tue, 13 Jan 2015 11:16:05 +0000
Subject: Removed the deprecated `custodian-instances` script.

This was designed to deploy multiple workers on a single
host, via consistent "runit" system.  It is no longer in use.
