<h1>
The Debian GNU/Linux FAQ
<br>Chapter 10 - Debian and the kernel
</h1>

<hr>

<h2><a name="s-non-debian-kernel"></a>10.1 Can I install and compile a kernel without some Debian-specific tweaking?</h2>

<p>
Yes.
</p>

<p>
There's only one common catch: the Debian C libraries are built with the most
recent <em>stable</em> releases of the <strong>kernel</strong> headers.  If you
happen to need to compile a program with kernel headers newer than the ones
from the stable branch, then you should either upgrade the package containing
the headers (<code>libc6-dev</code>), or use the new headers from an unpacked
tree of the newer kernel.  That is, if the kernel sources are in
<code>/usr/src/linux</code>, then you should add
<samp>-I/usr/src/linux/include/</samp> to your command line when compiling.
</p>

<hr>

<h2><a name="s-customkernel"></a>10.2 What tools does Debian provide to build custom kernels?</h2>

<p>
Users who wish to (or must) build a custom kernel are encouraged to download
the package <code>kernel-package</code>.  This package contains the script to
build the kernel package, and provides the capability to create a Debian
<code>linux-image-<var>version</var></code> package just by running the command
</p>

<pre>
     make-kpkg --initrd kernel_image
</pre>

<p>
in the top-level kernel source directory.  Help is available by executing the
command
</p>

<pre>
     make-kpkg --help
</pre>

<p>
and through the manual page <code>make-kpkg(1)</code>.
</p>

<p>
Users must separately download the source code for the most recent kernel (or
the kernel of their choice) from their favorite Linux archive site, unless a
<code>linux-source-<var>version</var></code> package is available (where
<var>version</var> stands for the kernel version).
</p>

<p>
Detailed instructions for using the <code>kernel-package</code> package are
given in the file <code>/usr/share/doc/kernel-package/README.gz</code>.
</p>

<hr>

<h2><a name="s-custombootdisk"></a>10.3 How can I make a custom boot floppy?</h2>

<p>
This task is greatly aided by the Debian package <code>boot-floppies</code>,
normally found in the <samp>admin</samp> section of the Debian FTP archive.
Shell scripts in this package produce boot floppies in the
<samp>SYSLINUX</samp> format.  These are <samp>MS-DOS</samp> formatted floppies
whose master boot records have been altered so that they boot Linux directly
(or whatever other operating system has been defined in the
<code>syslinux.cfg</code> file on the floppy).  Other scripts in this package
produce emergency root disks and can even reproduce the base disks.
</p>

<p>
You will find more information about this in the
<code>/usr/share/doc/boot-floppies/README</code> file after installing the
<code>boot-floppies</code> package.
</p>

<hr>

<h2><a name="s-modules"></a>10.4 What special provisions does Debian provide to deal with modules?</h2>

<p>
Debian's <code>modconf</code> package provides a shell script
(<code>/usr/sbin/modconf</code>) which can be used to customize the
configuration of modules.  This script presents a menu-based interface,
prompting the user for particulars on the loadable device drivers in his
system.  The responses are used to customize the file
<code>/etc/modules.conf</code> (which lists aliases, and other arguments that
must be used in conjunction with various modules) through files in
<code>/etc/modutils/</code>, and <code>/etc/modules</code> (which lists the
modules that must be loaded at boot time).
</p>

<p>
Like the (new) <code>Configure.help</code> files that are now available to
support the construction of custom kernels, the <code>modconf</code> package
comes with a series of help files (in <code>/usr/lib/modules_help/</code>)
which provide detailed information on appropriate arguments for each of the
modules.
</p>

<hr>

<h2><a name="s-removeoldkernel"></a>10.5 Can I safely de-install an old kernel package, and if so, how?</h2>

<p>
Yes.  The <code>linux-image-<var>NNN</var>.prerm</code> script checks to see
whether the kernel you are currently running is the same as the kernel you are
trying to de-install.  Therefore you can remove unwanted kernel image packages
using this command:
</p>

<pre>
     dpkg --purge linux-image-<var>NNN</var>
</pre>

<p>
(replace <var>NNN</var> with your kernel version and revision number, of
course)
</p>
