=head1 SYNOPSIS
usage: make-kpkg [options] [target [target ...]]
=cut
=head1 DESCRIPTION
This manual page explains the Debian B<make-kpkg> utility,
which is used to create the kernel related Debian packĀ
ages. This utility needs to be run from a top level Linux
kernel source directory.
=cut
=head1 OPTIONS
=over 3
=item B<--help> Print out a usage message.
=item B<--revision> number
=over 2
Sets the Debian revision number for the packages produced to the
argument B<number>. This has certain constraints: It only has an
effect during the configure phase. I suggest you run make-kpkg clean
unless you know what you are doing. Secondly, it may contain only
alphanumerics and the characters + . (full stop, and plus)
and must contain a digit. B<NOTE>: No hyphens allowed. (Look at the
Debian policy manual for details).
Optionally, you may prepend the revision with a digit followed by a colon (:)
This is because B<dpkg> imposes an ordering on version numbers,
so that it can tell whether packages are being up- or downgraded and
so that dselect can tell whether a package it finds available is
newer than the one installed on the system.
=back
=item B<--append-to-version> foo
=item B<--append_to_version> foo
This argument (B<foo>) is appended to the value of the EXTRAVERSION
variable present in the kernel Makefile. Since EXTRAVERSION is a
component of the kernel version, it is also added to the Debian
package name, and, as such must obey the policy governing the package
name. That means it may contain only B<lowercase> alphanumerics and
the characters - + . (full stop, hyphen, and plus). Uppercase letters
are not permitted under the Policy for a new package.
Please note that you must run a B<make-kpkg clean> after configuring
the kernel using make (x|menu)?config, since that creates
include/linux/version.h without the appended version I<foo>.
=back
=item B<--added-modules> foo
=item B<--added_modules> foo
=over 2
The argument should be a comma or space separated list of additional
add-on modules (not in the main kernel tree) that you wish to
build when you invoke the modules_blah targets. You may give full path
names of the directory the modules reside in, or just the module name
if it can be found in C<MODULE_LOC>, which defaults to /usr/src/modules.
The default is that all modules in C<MODULE_LOC> are compiled when
the modules_blah targets are invoked.
=back
=item B<--arch> foo
=over 2
Sets the architecture. This is mostly useful when cross compiling.
=back
=item B<--cross-compile> foo
=item B<--cross_compile> foo
=over 2
Sets the target string. This is mostly useful when cross compiling.
=back
=item B<--subarch> foo
=over 2
Some architectures (the Alpha, and the m68k) require a different
kernel for each subarchitecture. This option provides a way of
specifying it as an argument to make-kpkg. Please note that additional
support for subarchitectures may be required in the kernel sources to
actually make this do anything.
=back
=item B<--arch-in-name> foo
=item B<--arch_in_name> foo
=over 2
This option uses an extended name for the kernel image package by
embedding the subarchitecture in the image name, so one could write a
script to create multiple subarchitectures one after the other. You
may also do this by setting the environment variable ARCH_IN_NAME.
=back
=item B<--stem> foo
=over 2
This option determines the stem of the name of the packages. This is
set to C<kernel> by default. You may also do this by setting the
environment variable KPKG_STEM.
=item B<--pgpsign> name
=over 2
Set the string used to sign the B<changes> file for any external modules
in I</usr/src/modules/> using PGP. This option will override the builtin
default and the site wide customizations stored in the file
I</etc/kernel-pkg.conf>.
=back
=item B<--config> I<target>
=over 2
Change the type of configure done from the default C<oldconfig>.
I<target> must be one of C<oldconfig>, C<config>, C<menuconfig>,
C<xconfig>, C<gconfig>, or C<old>, C<menu>, C<g> or C<x>.
=back
=item B<--targets>
=over 2
Prints out a list of known targets. See the Section B<Targets> below.
=back
=item B<--noexec>
=over 2
Pass a B<-n> option to the I<make> so that commands are merely
printed to the screen but not actually executed. This is very
useful for debugging.
=back
=item B<--verbose>
=over 2
Pass a B<V=1> option to the I<make> so that commands are verbosely
printed to the screen while executed. This is very useful for debugging.
=back
=item B<--initrd>
=over 2
If make-kpkg is generating a linux-image package, perform any actions
necessary for a kernel loaded using initrd
This may include extra dependencies, and modifications to maintainer
scripts. It has no effect when make-kpkg is not making a linux-image
package.(The INITRD_OK variable is now obsolete).
=back
=item B<-j> -I<jobs>, B<--jobs> -I<jobs> Set CONCURRENCY_LEVEL=-I<jobs>
=item B<--overlay-dir> /path/to/directory
=over 2
The specified directory should contain files that will be placed in
C<./debian> directory of the kernel sources, in preparation to
building the debian packages. The files will replace anything in
C</usr/share/kernel-package> that would normally be placed there, and
it is up to the user to make sure that the files in the overlay
directory are compatible. f you break C<make-kpkg> with an overlay
file, you get to keep the pieces.
Please note that C<overlay-dir/Control> and C<overlay-dir/changelog>
are special, and variable substitution is done on these files.
If a C<overlay-dir/post-install> executable (or executable script)
exists, it shall be run immediately after C<./debian> is
populated. The script shall be executed in the C<./debian>
directory. This can be used, For instance, to delete files the user
does not want, or to take actions other than simple replacement.
=back
=item B<--zimage>
=over 2
Makes a zImage kernel rather than a bzImage kernel (the default).
Useful for people having problems with bzImage kernels.
=back
=item B<--bzimage>
=over 2
Makes a bzImage kernel. Useful for people who want a bzImage kernel
on sites where the default is zImage kernels.
=back
=item B<--rootcmd>
=over 2
The command that provides a means of gaining superuser access (for
example, `sudo' or `fakeroot') as needed by dpkg-buildpackages' C<-r>
option.
=back
=item B<--us>
=over 2
This option is passed to dpkg-buildpackage, and directs that package
not to sign the source. This is only relevant to the buildpackage
target.
=back
=item B<--uc>
=over 2
This option is passed to dpkg-buildpackage, and directs that package
not to sign the changelog. This is only relevant to the buildpackage
target.
=back
=back
The options may be shortened to the smallest unique string, and may be
entered with either a - or a -- prefix, and you may use a space or an
= symbol between an option string and a value. Please refer to man
Getopt::Long for details on how the options may be entered.

This target runs the targets B<clean>, B<build>, and B<binary>, and
produces the complete package using B<dpkg-buildpackage>.
=back
=item B<binary>
=over 3
This target produces all five Debian kernel packages by running the
targets B<kernel_source>, B<kernel_headers>, B<kernel_manual>,
B<kernel_doc> and B<kernel_image>.
=back
=item B<kernel_source>
=over 3
This target produces a debianised package of the Linux kernel
sources.
=back
=item B<kernel_headers>
=over 3
This target produces a Debian package containing the header files
included in the Linux kernel.
=back
=item B<kernel_doc>
=over 3
This target produces a Debian package containing the documentation
included in the Linux kernel.
=back
=item B<kernel_manual>
=over 3
This target produces a Debian package containing the section 9 manual
pages included in the Linux kernel.
=back
=item B<kernel_image>
=over 3
This target produces a Debian package of the Linux kernel source
image, and any modules configured in the kernel configuration file
I<.config>. On deletion, the package checks the version of the kernel
running, and refuses to delete a running kernel.
=back
=item B<kernel_debug>
=over 3
This target produces a Debian package of just the debugging symbols
for a linux kernel, and is not meant to be bootable.
=back
=item B<build>
=over 3
This target, used by target B<kernel_image> above, compiles the Linux
kernel image.
=back
=item B<modules>
=over 3
This target allows you to build all add-on modules and packages that
are very dependent on the precise kernel version they are compiled for
at the same time you build your kernel image. This target expects to
find the modules or packages under /usr/src/modules, and, for all such
directories, changes to I</usr/src/modules/x>, and runs the B<kdist> rule in
the local I<debian.rules> file. This target should create the B<Debian>
module package(s), and may also produce a compressed tar file, and a
compressed diff file, with I<md5sums> recorded in a changes file using
B<dpkg-genchanges>. The file is signed by the same identity that would
be used to sign the kernel packages.
=back
=item B<modules_config>
=over 3
This target allows you to configure all packages under
I</usr/src/modules>.
=back
=item B<modules_image>
=over 3
This target allows you to build all packages under I</usr/src/modules>,
but does not create the source or diff files, and does not create and
sign a changes file.
=back
=item B<modules_clean>
=over 3
This target allows you to clean the modules directories.
=back
=item B<configure>
=over 3
This target allows people to create the debian directory and create a
configuration timestamp, so that any special edits to
configuration-generated files are not stomped over later.

=head1 FILES
Apart from the runtime options, the debian.rules file run by B<make-kpkg>
also looks for site-wide defaults in the file I</etc/kernel-pkg.conf>.
The default configuration allows there to be a site wide override for
the full name and email address of the person responsible for
maintaining the kernel packages on the site, but the
I</etc/kernel-pkg.conf> file is actually a I<Makefile> snippet, and any
legal make directives may be included in there. B<Note>: Caution is
urged with this file, since you can totally change the way that the
make is run by suitably editing this file. Please look at
I</usr/share/doc/kernel-package/Problems.gz> for a list of known
problems while compiling kernel images.
