  35. <para>The Linux kernel needs to expose an Application Programming Interface
  36. (API) for the system's C library (Glibc in LFS) to use. This is done
  37. by way of sanitizing various C header files that are shipped in the Linux
  38. kernel source tarball.</para>

  41. <para>Now extract the user-visible kernel headers from the source.
  42. They are placed in an intermediate local directory and copied to the needed
  43. location because the extraction process removes any existing files in
  44. the target directory.</para>
