+ <para>
+ <command>kernel-install</command> is used to install and remove kernel and

+ </para>
+
+ <para><command>kernel-install</command> will execute the files
+ located in the directory <filename>/usr/lib/kernel/install.d/</filename>
+ and the local administration directory <filename>/etc/kernel/install.d/</filename>.
+ All files are collectively sorted and executed in lexical order, regardless of the directory in
+ which they live. However, files with identical filenames replace each other.
+ Files in <filename>/etc/kernel/install.d/</filename> take precedence over files with the same name
+ in <filename>/usr/lib/kernel/install.d/</filename>. This can be used to override a system-supplied
+ executables with a local file if needed; a symbolic link in <filename>/etc/kernel/install.d/</filename>
+ with the same name as an executable in <filename>/usr/lib/kernel/install.d/</filename>,
+ pointing to <filename>/dev/null</filename>, disables the executable entirely. Executables must have the
+ extension <literal>.install</literal>; other extensions are ignored.</para>
+
+ <para>An executable should return <constant>0</constant> on success. It may also
+ return <constant>77</constant> to cause the whole operation to terminate
+ (executables later in lexical order will be skipped).</para>
