Cloud Init script for building a coreos cluster at home on XenServer using Cloud-Init and ETCD2

This Cloud-init script can be used to bootstrap a Xen based CoreOS server through Xen orchestra.

Features;

  1. Workaround for the lack of /etc/environment on 'unsupported' hypervisors
  2. Static IP allocation to deal with dhcp causing problems (On my network at least)
  3. etcd2 bootstrap discovery using public service and discovery tokens
    1. Manual reconfiguration to allow for membership changes after cluster is operational

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.
