+#       askfirst and respawn are started next.
+#       For askfirst, before running the specified process, init displays
+#       the line "Please press Enter to activate this console"
+#       and then waits for the user to press enter before starting it.
+#
+#       shutdown actions are run on halt/reboot/poweroff, or on SIGQUIT.
+#       Then the machine is halted/rebooted/powered off, or for SIGQUIT,
+#       restart action is exec'ed (init process is replaced by that process).
+#       If no restart action specified, SIGQUIT has no effect.
+#
+#       ctrlaltdel actions are run when SIGINT is received
+#       (this might be initiated by Ctrl-Alt-Del key combination).
+#       After they complete, normal processing of askfirst / respawn resumes.
