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

<footnote>

<para>Nowadays actually CPIO archives used as an "initramfs", rather than "initrd". See

to and from the boot loader partition, referred to as <varname>$BOOT</varname> here. It will usually be
|
|
one of <filename>/boot/</filename>, <filename>/efi/</filename>, or <filename>/boot/efi/</filename>, see
|
|
below.</para>
|
|
|
|
<para><command>kernel-install</command> will run the executable files ("plugins") 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 placed in these directories 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>

<title>Commands</title>

<para>The following commands are understood:</para>

<variablelist>

|
|
<listitem>
|
|
<para>This command expects a kernel version string and a path to a kernel image file as arguments.
|
|
Optionally, one or more initrd images may be specified as well (note that plugins might generate
|
|
additional ones). <command>kernel-install</command> calls the executable files from
|
|
<filename>/usr/lib/kernel/install.d/*.install</filename> and
|
|
<filename>/etc/kernel/install.d/*.install</filename> (i.e. the plugins) with the following
|
|
arguments:</para>
|
|
|
|
<programlisting>add <replaceable>KERNEL-VERSION</replaceable> <filename>$BOOT/<replaceable>ENTRY-TOKEN</replaceable>/<replaceable>KERNEL-VERSION</replaceable>/</filename> <replaceable>KERNEL-IMAGE</replaceable> [<replaceable>INITRD-FILE</replaceable> ...]</programlisting>
|
|
|
|
<para>The third argument directly refers to the path where to place kernel images, initrd
|
|
images and other resources for <ulink url="https://uapi-group.org/specifications/specs/boot_loader_specification">Boot
|
|
Loader Specification</ulink> Type #1 entries (the "entry directory"). If other boot loader schemes
|
|
are used the parameter may be ignored. The <replaceable>ENTRY-TOKEN</replaceable> string is
|
|
typically the machine ID and is supposed to identify the local installation on the system. For
|
|
details see below.</para>

|

If <replaceable>INITRD-FILE</replaceable>s are provided, it also copies them to
|

<filename>$BOOT/<replaceable>ENTRY-TOKEN</replaceable>/<replaceable>KERNEL_VERSION</replaceable>/<replaceable>INITRD-FILE</replaceable></filename>.

It also creates a boot loader entry according to the <ulink

|

<filename>$BOOT/loader/entries/<replaceable>ENTRY-TOKEN</replaceable>-<replaceable>KERNEL-VERSION</replaceable>.conf</filename>.
|

The title of the entry is the <replaceable>PRETTY_NAME</replaceable> parameter specified in

<para>If <option>--verbose</option> is used, <varname>$KERNEL_INSTALL_VERBOSE=1</varname> will be
|
|
exported for plugins. They may output additional logs in this case.</para>
|
|
|
|
<para><varname>$KERNEL_INSTALL_MACHINE_ID</varname> is set for the plugins to the desired machine-id to
|
|
use. It's always a 128-bit ID. Normally it's read from <filename>/etc/machine-id</filename>, but it can
|
|
also be overridden via <varname>$MACHINE_ID</varname> (see below). If not specified via these methods,
|
|
a fallback value will generated by <command>kernel-install</command> and used only for a single
|
|
invocation.</para>
|
|
|
|
<para><varname>$KERNEL_INSTALL_ENTRY_TOKEN</varname> is set for the plugins to the desired entry
|
|
"token" to use. It's an identifier that shall be used to identify the local installation, and is often
|
|
the machine ID, i.e. same as <varname>$KERNEL_INSTALL_MACHINE_ID</varname>, but might also be a
|
|
different type of identifier, for example a fixed string or the <varname>ID=</varname>,
|
|
<varname>IMAGE_ID=</varname> values from <filename>/etc/os-release</filename>. The string passed here
|
|
will be used to name Boot Loader Specification entries, or the directories the kernel image and initial
|
|
RAM disk images are placed into.</para>
|
|
|
|
<para>Note that while <varname>$KERNEL_INSTALL_ENTRY_TOKEN</varname> and
|
|
<varname>$KERNEL_INSTALL_MACHINE_ID</varname> are often set to the same value, the latter is guaranteed
|
|
to be a valid 32 character ID in lowercase hexadecimals while the former can be any short string. The
|
|
entry token to use is read from <filename>/etc/kernel/entry-token</filename>, if it exists. Otherwise a
|
|
few possible candidates below <varname>$BOOT</varname> are checked for Boot Loader Specification Type 1
|
|
entry directories, and if found the entry token is derived from that. If that is not successful,
|
|
<varname>$KERNEL_INSTALL_MACHINE_ID</varname> is used as fallback.</para>
|
|
|
|
<para><varname>$KERNEL_INSTALL_BOOT_ROOT</varname> is set for the plugins to the absolute path of the
|
|
root directory (mount point, usually) of the hierarchy where boot loader entries, kernel images, and
|
|
associated resources should be placed. This usually is the path where the XBOOTLDR partition or the ESP
|
|
(EFI System Partition) are mounted, and also conceptually referred to as <varname>$BOOT</varname>. Can
|
|
be overridden by setting <varname>$BOOT_ROOT</varname> (see below).</para>
|
|
|
|
<para><varname>$KERNEL_INSTALL_LAYOUT=bls|uki|other|...</varname> is set for the plugins to specify the
|
|
installation layout. Defaults to <option>bls</option> if
|
|
<filename>$BOOT/<replaceable>ENTRY-TOKEN</replaceable></filename> exists, or <option>other</option>
|
|
otherwise. Additional layout names may be defined by convention. If a plugin uses a special layout,
|
|
it's encouraged to declare its own layout name and configure <varname>layout=</varname> in
|
|
<filename>install.conf</filename> upon initial installation. The following values are currently

understood:</para>
