# We run dnsmasq via the /etc/init.d/dnsmasq script which acts as a
# wrapper picking up extra configuration files and then execs dnsmasq
# itself, when called with the "systemd-exec" function.

# (from upstream)
# The systemd-*-resolvconf functions configure (and deconfigure)
# resolvconf to work with the dnsmasq DNS server. They're called like
# this to get correct error handling (ie don't start-resolvconf if the
# dnsmasq daemon fails to start.
