# that it provides as the default.  Otherwise use /etc/resolv.conf as
# the default.

# If IGNORE_RESOLVCONF is set in /etc/default/dnsmasq or an explicit
# filename is set there then this inhibits the use of the resolvconf-provided
# information.

# Note that if the resolvconf package is installed it is not possible to
# override it just by configuration in /etc/dnsmasq.conf, it is necessary
# to set IGNORE_RESOLVCONF=yes in /etc/default/dnsmasq.
