# Test the config file and refuse starting if it is not valid.
ExecStartPre=/usr/sbin/dnsmasq --test

# 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.
#
# It also adds the command-line flags
#    --keep-in-foreground --pid-file --enable-dbus 
# to disable writing a pid-file (not needed with systemd) and 
# enable DBus by default because we use DBus activation.
#
ExecStart=/etc/init.d/dnsmasq systemd-exec

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