# Restconf direct start/stop using RPC and config enable flag (as alternative to systemd or other)
# According tot he following behaviour:
# - on RPC start, if enable is true, start the service, if false, error or ignore it
# - on RPC stop, stop the service
# - on backend start make the state as configured
# - on enable change, make the state as configured
# - No restconf config means enable: false (extra rule)
# See test_restconf_netns for network namespaces
# Magic line must be first in script (see README.md)
