docker-register.service

	# I was hoping that marking this service global would allow me to start it with:
	#
	# fleetctl load docker-register.service
	#
	# Instead, I had to go onto each CoreOS host and do:
	#
	# cp docker-register.service /etc/systemd/system/
	# systemctl enable docker-register.service
	# systemctl start docker-register.service

rspec spies: spy on unstubbed method

	# This spec demonstrates how rspec's and_call_original
	# allows spying on real objects without affecting their
	# behaviour. In the following output from rspec, note
	# that real output ("Moo!") actually goes to $stdout,
	# even though the latter's puts method was stubbed.
	#
	# Cow
	# before it speaks
	# is considered quiet
	# when it speaks
