    2222    libraries. They are unneeded and potentially harmful when using dynamic

     43      backed up for later reuse. In case of fatal failures in the subsequent

     45      (more carefully) is the best option to recover. Unfortunately, all the
     46      temporary files will be removed, too. To avoid spending extra time to
     47      redo something which has been built successfully, creating a backup of
     48      the current LFS system may prove useful.
