# This is written under the assumption that p4broker was installed via the
# official package distribution (and not some custom way). All broker nodes
# have configuration that lives in ${BASE_DIR}/${NODE_NAME}/broker.cfg.
#
# This broker.cfg file should be split into two separate components that live
# in the individual node directory:
#  - header.inc
#  - maintenance.inc
#
# The header is the normal broker config during regular operation.
#
# The maintenance is a file that will be apprended to the header whenever
# maintenance is on. It should contain the word 'maintenance' SOMEWHERE in it,
# and similarly the header file should NOT contain the word. This is used to
# determine the current state of the node's config.
