the choices saved in the .config file. If there is no such file, it behaves like make config, a text
interface that asks all questions (hundreds of them) one a time. If the .config file already exists
but doesn't mention all the existing options, then this method will only ask questions for which
the file has no saved answer.
TIP
make-kpkg --config
make-kpkg can be told to use configuration methods other than make oldco
nfig, by indicating the target (menuconfig, xconfig or gconfig) in the makekpkg
invocation with the --config option.
8.10.4. Compiling and Building the Package
NOTE
Clean up before rebuilding
If you have already compiled once in the directory and wish to recompile with
new sources, you must run fakeroot make-kpkg clean. Additionally, this
allows generating a package with a new name (different --append-to-version
seing).
TIP
Kernel package headers
make-kpkg uses information contained in the /etc/kernel-pkg.conf file to
generate headers for the Debian kernel package. It is recommended to edit
this file with correct information if you wish to publish your kernel package.
Once the kernel configuration is ready, the make-kpkg command provided by Debian compiles
the kernel, then generates the corresponding Debian package (or packages). Just like make,
make-kpkg takes the name of a target to execute as an argument: kernel-image generates a compiled
kernel package, kernel-doc a package containing the documentation included with the
kernel, kernel-headers a package of kernel header files (.h files for the kernel in the include/
directory, which is useful for compilation of some external modules), and kernel-source creates
a package containing the kernel sources.
make-kpkg also accepts several parameters: --append-to-version suffix appends suffix to the
name of the kernel; the suffix is also included in the package name. --revision revision defines
the version number of the package generated. Debian uses certain suffixes to identify standard
kernels, compiled specifically for a given processor, or with certain options (-486, -686, -686-
bigmem, -amd64, -vserver-686, -vserver-686-bigmem, -openvz-686, -xen-686). These suffixes
are best avoided for local packages, so that they can be easily recognized from official packages
issued by the Debian project.
The make-kpkg program performs actions normally restricted to the root user when creating
the Debian package; however, it can be tricked into working under a normal user's identity,
with fakeroot (see sidebar “fakeroot” (page 414)).
