# This spec demonstrates how rspec's and_call_original

# that real output ("Moo!") actually goes to $stdout,

# 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
