+# This is a "morph deploy" configure extension to configure a Baserock
+# build node, as part of a distributed building cluster. It uses the
+# following variables from the environment:
+#
+# * DISTBUILD_CONTROLLER: if 'yes', machine is set up as the controller.
+# * DISTBUILD_WORKER: if 'yes', machine is set up as a worker.
+# * TROVE_ID: hostname and Trove prefix of the server to pull source
+# from and push built artifacts to.
+#
+# The following variable is optional:
+#
+# * ARTIFACT_CACHE_SERVER: by default artifacts are pushed to the same
+# Trove that served the source, but you can use a different one.
+#
+# The following variable is required for worker nodes only:
+#
+# * CONTROLLERHOST: hostname or IP address of distbuild controller machine.
+# * WORKER_SSH_KEY: identity used to authenticate with Trove
+#
+# The following variable is required for the controller node only:
+#
+# * WORKERS: hostnames or IP address of worker nodes, comma-separated.
+

+# that when users invoke "morph", they don't need to manually
+# specify it, or to manually add another configuration file to
+# use. However, the setting may only be set for the distbuild
+# initiator (which is what the user invokes), so in ALL other
+# configuration files we unset it.

+# We disable the disk space requirement checks on non-worker nodes.
