From d345b36b483fec8fb2def5f3acdc2d3c5faa94eb Mon Sep 17 00:00:00 2001
From: Dan McGee <dan@archlinux.org>
Date: Sun, 19 Jun 2011 16:04:25 -0500
Subject: [PATCH] Set hostname via /proc if file is available
On Linux, the hostname can be set via this file if available, precluding
the need for a `hostname` binary.
