<title>Installation of the kernel headers</title>
|
|
|
|
<para>We won't be compiling a new kernel yet -- we'll do that when we have
|
|
finished the installation of all the packages. But as some packages need the
|
|
kernel header files, we're going to unpack the kernel archive now, set it up,
|
|
and copy the header files to where they will be found by these packages.</para>
|
|
|
|
<para>It is important to note that the files in the kernel source directory
|
|
are not owned by root. Whenever you unpack a package as user root (like we
|
|
do here inside chroot), the files end up having the user and group ID's of
|
|
whatever they were on the packager's computer. This is usually not a
|
|
problem for any other package you install because you remove the source
|
|
tree after the installation. But the Linux kernel source tree is often kept
|
|
around for a long time, so there's a chance whatever userid was used will
|
|
be assigned to somebody on your machine, and that person would get write
|
|
access to the kernel source.</para>
|
|
|
|
<para>In light of this, you might want to run <userinput>chown
|
|
0.0</userinput> on the linux-&kernel-version; directory to ensure all files
|
|
are owned by user <emphasis>root</emphasis>.</para>
|
|
|
|
<para>The kernel headers are installed by running the following
|
|
commands:</para>
|
|
|
|

|
