# Script to make a cluster for testing unit files stuck in a "No such
# file or directory" state.

# We make 5 nodes, all set up with etcd & fleet on CoreOS, but
# otherwise nothing special.

# Note: The environment variable SSH_SOURCE_CIDR should be set to a
# CIDR where you'd like to ssh from. In our case, this is the external
# address of our corporate firewall; obviously it'll be something
# different for other people.
