+          By default, when the kernel crash is captured, the root file system is mounted, and <command>/sbin/init</command> is run. To change this behavior, open the <filename>/etc/kdump.conf</filename> configuration file in a text editor such as <application>vi</application> or <application>nano</application>, remove the hash sign (<quote>#</quote>) from the beginning of the <literal>#default shell</literal> line, and replace the value with a desired action as described in <xref linkend="table-kdump-configuration-cli-action-actions" />. For example:
