<para>There are two main reasons for the kernel version requirement. First,
the Native POSIX Threading Library (NPTL) test suite will segfault if the
host's kernel has not been compiled with GCC-3.0 or a later version. Second,
the 2.6.2 or later version of the kernel is required for the use of Udev.
Udev creates devices dynamically by reading from the <systemitem
class="filesystem">sysfs</systemitem> file system. However, support for this
filesystem has only recently been implemented in most of the kernel drivers.
We must be sure that all critical system devices get created properly.</para>
<para>The reason for the kernel version requirement is that TLS support in
Binutils don't be built and the Native POSIX Threading Library (NPTL)
test suite will segfault if the host's kernel isn't a 2.6 kernel and has
not been compiled with GCC-3.0 or a later version.</para>

outlined above, run the following command:</para>

compiling the kernel and configuring the boot loader (assuming the host
uses GRUB) are located in <xref linkend="chapter-bootable"/>.</para>
