+# Note that this recipe explicitly creates a serial-getty@ service for every tty
+# in SERIAL_CONSOLES. This is typically not always needed with systemd as it
+# will probe at boot and generate getty instances for any active consoles as
+# required.  This recipe (enabled via disabling serial-getty-generator in systemd)
+# should only be used if the generator is not appropriate.
