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>9.2 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>kernel-image-<var>version</var></code> package just by running the -command -</p> - -<pre> - make-kpkg 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>kernel-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>. -Briefly, one should: -</p> -<ul> -<li> -<p> -Unpack the kernel sources, and <samp>cd</samp> to the newly created directory. -</p> -</li> -</ul> -<ul> -<li> -<p> -Modify the kernel configuration using one of these commands: -</p> -<ul> -<li> -<p> -<samp>make config</samp> (for a text-based interface). -</p> -</li> -</ul> -<ul> -<li> -<p> -<samp>make menuconfig</samp> (for an ncurses-based menu driven interface). -Note that to use this option, the <code>libncurses5-dev</code> package must be -installed. -</p> -</li> -</ul> -<ul> -<li> -<p> -<samp>make xconfig</samp> (for an X11 interface). Using this option requires -that relevant X and Tcl/Tk packages be installed. -</p> -</li> -</ul> - -<p> -Any of the above steps generates a new <samp>.config</samp> in the top-level -kernel source directory. -</p> -</li> -</ul> -<ul> -<li> -<p> -Execute the command: <samp>make-kpkg -rev Custom.<var>N</var> -kernel_image</samp>, where <var>N</var> is a revision number assigned by the -user. The new Debian archive thus formed would have revision -Custom.<var>N</var>, e.g. <code>kernel-image-2.2.14_Custom.1_i386.deb</code> -for the Linux kernel 2.2.14 on i386. -</p> -</li> -</ul> -<ul> -<li> -<p> -Install the package created. -</p> -<ul> -<li> -<p> -Run <samp>dpkg --install -../kernel-image-<var>VVV</var>_Custom.<var>N</var>_i386.deb</samp> to install -the kernel itself. The installation script will: -</p> -<ul> -<li> -<p> -run the boot loader (grub, LILO or some other) if needed, -</p> -</li> -</ul> -<ul> -<li> -<p> -install the custom kernel in -<code>/boot/vmlinuz_<var>VVV</var>-Custom.<var>N</var></code>, and set up -appropriate symbolic links to the most recent kernel version. -</p> -</li> -</ul> -<ul> -<li> -<p> -prompt the user to make a boot floppy. This boot floppy will contain the raw -kernel only. See <a href="#s-custombootdisk">How can I make a custom boot -floppy?, Section 9.3</a>. -</p> -</li> -</ul> -</li> -</ul> -<ul> -<li> -<p> -To employ secondary boot loaders such as <code>loadlin</code>, copy this image -to other locations (e.g. to an <samp>MS-DOS</samp> partition). -</p> -</li> -</ul> -</li> -</ul> - -<hr> - -<h2><a name="s-custombootdisk"></a>9.3 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>9.4 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>9.5 Can I safely de-install an old kernel package, and if so, how?</h2> - -<p> -Yes. The <code>kernel-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 --force-remove-essential kernel-image-<var>NNN</var> -</pre> - -<p> -(replace <var>NNN</var> with your kernel version and revision number, of -course) -</p> - -<hr> - -<p> -[ <a href="ch-uptodate.en.html">previous</a> ] -[ <a href="index.en.html#contents">Contents</a> ] -[ <a href="ch-basic_defs.en.html">1</a> ] -[ <a href="ch-getting.en.html">2</a> ] -[ <a href="ch-compat.en.html">3</a> ] -[ <a href="ch-software.en.html">4</a> ] -[ <a href="ch-ftparchives.en.html">5</a> ] -[ <a href="ch-pkg_basics.en.html">6</a> ] -[ <a href="ch-pkgtools.en.html">7</a> ] -[ <a href="ch-uptodate.en.html">8</a> ] -[ 9 ] -[ <a href="ch-customizing.en.html">10</a> ] -[ <a href="ch-support.en.html">11</a> ] -[ <a href="ch-contributing.en.html">12</a> ] -[ <a href="ch-redistrib.en.html">13</a> ] -[ <a href="ch-nexttime.en.html">14</a> ] -[ <a href="ch-faqinfo.en.html">15</a> ] -[ <a href="ch-customizing.en.html">next</a> ] -</p> - -<hr> - -<p> -The Debian GNU/Linux FAQ -</p> - -<address> -version 3.1.5, 17 January 2007<br> -<br> -Authors are listed at <a href="ch-faqinfo.en.html#s-authors">Debian FAQ Authors</a><br> -<br> -</address> -<hr> - -</body> - -</html> - +ch-kernel.en.html
