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

# Enable DBus by default because we use DBus activation.
#
# Drop privileges and become the 'dnsmasq' user. It is recommended by dnsmasq
# upstream to run dnsmasq as an isolated user that does not run any other
# processes, owns no files and has no shell. The default 'nobody' user has a
# shell and might be used for other processes.
#
# Debian-specific: add /etc/dnsmasq.d to config search path (with the exception
# of .dpkg-*). Packages such as libvirt leave config files there.
#
# --pid-file without argument disables writing a PIDfile, we don't need one.
