-<title>Why we copy the kernel headers and don't symlink them</title>
-
-<para>In the past, it was common practice for people to symlink the
-/usr/include/linux and asm directories to /usr/src/linux/include/linux
-and asm respectively. This is a <emphasis>bad</emphasis> idea as
-this extract from a post by Linus Torvalds to the Linux Kernel
-Mailing List points out:</para>
-
-<screen>I would suggest that people who compile new kernels should:
-
- - not have a single symbolic link in sight (except the one that the
- kernel build itself sets up, namely the "linux/include/asm" symlink
- that is only used for the internal kernel compile itself)
-
-And yes, this is what I do. My /usr/src/linux still has the old 2.2.13
-header files, even though I haven't run a 2.2.13 kernel in a _loong_
-time. But those headers were what glibc was compiled against, so those
-headers are what matches the library object files.
-
-And this is actually what has been the suggested environment for at
-least the last five years. I don't know why the symlink business keeps
-on living on, like a bad zombie. Pretty much every distribution still
-has that broken symlink, and people still remember that the linux
-sources should go into "/usr/src/linux" even though that hasn't been
-true in a _loong_ time.</screen>
-
-<para>The relevant part here is where he states that the headers should
-be the ones which <emphasis>glibc was compiled against</emphasis>. These are
-the headers which should remain accessible and so by copying them, we ensure
-that we follow these guidelines. Also note that as long as you don't have
-those symlinks, it is perfectly fine to have the kernel sources
-in <filename>/usr/src/linux</filename>.</para>
