# Script to add global static routes to the system
#
#
### BEGIN INIT INFO
# Provides: networking-routes
# Required-Start: $network $local_fs
# Required-Stop: $local_fs
# Default-Start: S
# Default-Stop:
# Short-Description: Establish global networking routes for the system
# Description: Define global network routes for the system using
# the configuration defined in /etc/network/routes
# Global routes can be either routes for which
# the associated interface cannot be determined
# beforehand (maybe the device name is not known)
# or 'reject' routes to prevent the system from
# communicating with remote networks.
