<para>The reason for the kernel version requirement is that we specify
that version when building <application>glibc</application> in
<xref linkend="chapter-cross-tools"/> and
<xref linkend="chapter-building-system"/>,
at the recommendation of the developers. It is also required by
udev.</para>
<para>If the host kernel is earlier than &min-kernel; you will need to replace
the kernel with a more up to date version. There are two ways
you can go about this. First, see if your Linux vendor provides a &min-kernel;
or later kernel package. If so, you may wish to install it. If your
vendor doesn't offer an acceptable kernel package, or you would prefer not to
install it, you can compile a kernel yourself. Instructions for
compiling the kernel and configuring the boot loader (assuming the host
uses GRUB) are located in <xref linkend="chapter-bootable"/>.</para>
