+description     "Job to trigger boot services"
+author          "chromium-os-dev@chromium.org"
+
+# This job is used as a milestone marker for jobs that are run at
+# system boot right after chromeos_startup.
+#
+# Specifically, tasks that should start right after chromeos_startup should
+# use syntax like:
+#   start on starting boot-services
+#   stop on stopping boot-services
+#
+# Tasks that want to wait for all boot services to be ready should use
+# syntax like:
+#   start on started boot-services
+
+# In startup.conf we see "telinit 2", which kicks us off.
+start on runlevel 2
+stop on starting halt or starting reboot
+
+# We purposely omit the main process.  upstart marks us running
+# on the first event, and ignores all subsequent events until we
+# stop.
