# We can't really know when networking is actually up and running from
# a simple "Required-Start: $network", so instead just use curl with
# a bunch of retries and hope it works. We could use more sophisticated
# dependency mechanisms provided by systemd, but ideally we can just use
# a single script to service both CentOS 6.5 and CentOS 7 installs, hence
# reasoning for using `wget --retry-connrefused` below. Using `curl --retry`
# fails immediately because it only handles connection timeouts, not connection
# refused cases.
# See https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/

# Nothing wrong with set -e here since we're not doing anything complex
set -e
