Currently, the ${CLFS} directory and
        all of its subdirectories are owned by the user clfs, a user that exists only on the host system.
        For security reasons, the ${CLFS} root directory and all of its
        subdirectories should be owned by root. Change the ownership for ${CLFS} and its
        subdirectories by running this command:
      
chown -Rv 0:0 ${CLFS}
      
        The following files are to be owned by the group utmp not by root.
      
chgrp -v 13 ${CLFS}/var/run/utmp ${CLFS}/var/log/lastlog
