This document will mainly describe how to use the following options and give examples. Thanks.

Maybe we should add one paragraph to introduce /etc/sysconfig/kdump.


The configuration file for `kdump` kernel is `/etc/sysconfig/kdump`. `etc/sysconfig/kdump` controls the `kdump` kernel command line parameters. And there are only two main options we need to modify, KDUMP_COMMANDLINE_REMOVE and KDUMP_COMMANDLINE_APPEND.

KDUMP_COMMANDLINE_REMOVE
------------------------

...

KDUMP_COMMANDLINE_APPEND
------------------------

...

For the rest of options, refer to the "/etc/sysconfig/kdump".
