### BEGIN INIT INFO
# Provides:          resolvconf
# Required-Start:    $local_fs
# Required-Stop:     $local_fs
# X-Start-Before:    networking ifupdown
# Default-Start:     S
# Default-Stop:      0 6
# Short-Description: Nameserver information manager
# Description:       This service manages the list of nameserver addresses
#                    used by the libc resolver and name service caches
### END INIT INFO
#
# This file is part of the resolvconf package.
#
# We really need "X-Stop-Before: networking ifupdown" too because
# terminal ifdowns shouldn't update resolv.conf;
# however there is unfortunately no such thing as "X-Stop-Before".
#
# This file is not used in Ubuntu.
#

# Don't use set -e; check return status instead.
