+    <title>Description</title>
+    <para>
+      <command>kernel-install</command> is used to install and remove kernel and
+      initramfs images to and from <filename>/boot</filename>.
+    </para>
+
+    <para>kernel-install 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 directories in
+    which they live. However, files with identical file names 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 /dev/null, disables the executable entirely. Executables must have the
+    extension .install; other extensions are ignored.</para>
