+    <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><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 /dev/null, disables the executable entirely. Executables must have the
+    extension <literal>.install</literal>; other extensions are ignored.</para>

+          <filename>/usr/lib/kernel/install.d/*.install</filename> and

+          It also creates a boot loader entry according to the boot
+          loader specification in
+          <filename>/boot/loader/entries/<replaceable>MACHINE-ID</replaceable>-<replaceable>KERNEL-VERSION</replaceable>.conf</filename>.

+          missing), or "GNU/Linux
+          <replaceable>KERNEL-VERSION</replaceable>", if unset.  If
+          the file <filename>initrd</filename> is found next to the
