Similar to
<link linkend='var-SERIAL_CONSOLES'><filename>SERIAL_CONSOLES</filename></link>
except the device is checked for existence before attempting
to enable it.
Specifies serial consoles, which must be listed in
<link linkend='var-SERIAL_CONSOLES'><filename>SERIAL_CONSOLES</filename></link>,
to check against <filename>/proc/console</filename>
before enabling them using getty.
This variable allows aliasing in the format:
&lt;device&gt;:&lt;alias&gt;.
If a device was listed as "sclp_line0"
in <filename>/dev/</filename> and "ttyS0" was listed
in <filename>/proc/console</filename>, you would do the
following:
<literallayout class='monospaced'>
SERIAL_CONSOLES_CHECK = "slcp_line0:ttyS0"
</literallayout>
This variable is currently only supported with SysVinit
(i.e. not with systemd).
