+# This oneshot service checks for /usr/bin/{reboot,poweroff,halt,shutdown}
+# and if they are part of runit-void it renames them and copies the 66 
+# utilities in their place. It must be enabled, especially if one
+# changes between the two init systems. There is a similar script in
+# runit core-services -part of the boot-66serv package- that does the
+# opposite and runs by default with runit. 
+# The service makes sure that the user has the proper utilities for the 
+# init system they are currently running.
