+a backup copy is made though. Information is read out of these
+backup copies and restored to the new files by the
+loncaparestoreconfigurations script. To ensure that
+new file permissions and ownerships are installed, a final set of
+chown and chmod commands are called for each of
+the configuration files.

+If you are truly paranoid, you can just make the +Makefile.configinstall file and then save, copy, +and restore all the configuration values yourself. +loncaparestoreconfigurations is pretty smart though, has yet to +fail, and besides, a backup copy is always made (time-stamped so that backup +copies are not overwritten). +
