-      listed as "sclp_line0" in ``/dev/`` and "ttyS0" was listed in
-      ``/proc/console``, you would do the following::
-
-         SERIAL_CONSOLES_CHECK = "slcp_line0:ttyS0"

-      This variable is currently only supported with SysVinit (i.e. not
-      with systemd). Note that :term:`SERIAL_CONSOLES_CHECK` also requires
