 <title>Host System Requirements</title>
 <?dbhtml filename="hostreqs.html"?>
 
-<para>See testing.</para>
+<para>The host must be running at least a 2.6.2 kernel compiled with
+GCC-3.0 or higher. There are two main reasons for this high
+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. Secondly, 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>In order to determine whether the host kernel meets the
+requirements outlined above, run the following command:</para>
+
+<screen><userinput>cat /proc/version</userinput></screen>
+
+<para>This will produce output similar to:</para>
+
+<screen><computeroutput>Linux version 2.6.2 (user@host) (gcc version 3.4.0) #1
+    Tue Apr 20 21:22:18 GMT 2004</computeroutput></screen>
+
+<para>If the results of the above command state that the host kernel
+was not compiled using a GCC-3.0 (or later) compiler, one will need to
+be compiled.  The host system will then need to be rebooted to use the
+newly compiled kernel. Instructions for compiling the kernel and
+configuring the boot loader (assuming the host uses GRUB) are located
+in <xref linkend="chapter-bootable"/>.</para>
