13 | <para>LFS is designed to be built in one session. That is, the

14 | instructions assume that the system will not be shut down

15 | during the process. This does not mean that the system has to
|
---|
16 | be built in one sitting. The issue is that certain procedures
|

17 | must be repeated after a reboot when resuming LFS at
|

18 | different points.</para>
