+  <para>LFS is designed to be built in one session.  That is, the
+  instructions assume that the system will not be shut down
+  during the process.  That does not mean that the system has to
+  be done in one sitting.  The issue is that certain procedures
+  have to be re-accomplished after a reboot if resuming LFS at
+  different points.</para>
