7.7. Configure Red Hat Linux
Red Hat Linux stores parameters concerning system start up in
the file /etc/sysconfig/init.
Alter the parameter BOOTUP to use
terminal-independent commands to write the
OK,
PASSED and
FAILED messages. These messages
will no longer appear in green, yellow or red. The comments in
/etc/sysconfig/init suggest that any value
other than color will do, but it seems that
BOOTUP must be set to
serial.
Alter the PROMPT parameter to disallow
interactive start up. Allowing an unauthenticated keystroke to stop
system services is not robust against line noise and allows anyone
that dials in during system boot to deny services.
Red Hat Linux runs a hardware
discoverer, named kudzu. When
attempting to identify a serial port
Kudzu resets the serial port. This
stops the serial console. Kudzu is
configured from the file
/etc/sysconfig/kudzu.
Kudzu can be prevented from
resetting hardware by setting the configuration parameter
SAFE to yes.
