   For safety reasons (so as to not mess up a machine's configuration),
   configuration files are NOT installed during this step.  This means
   that files such as /etc/httpd/access.conf, /etc/smb.conf, /etc/atalk/config,
   /home/httpd/html/res/adm/includes/copyright.tab, and
   /home/httpd/spare.tab are not overwritten, but remain as old, non-updated
   copies.  (To automatically update these files and save/restore
   their encoded machine configuration, you must run "make configinstall").

   Configuration files are installed during this step.  This means
   that files such as /etc/httpd/access.conf, /etc/smb.conf, /etc/atalk/config,
   /home/httpd/html/res/adm/includes/copyright.tab, and
   /home/httpd/spare.tab are overwritten.  Before being overwritten,
   a backup copy is made though.  Information is read out of these
   backup copies and restored to the new files by the
   <TT>loncaparestoreconfigurations</TT> script.  To ensure that
   new file permissions and ownerships are installed, a final set of
   <TT>chown</TT> and <TT>chmod</TT> commands are called upon all
   the configuration files.

   <STRONG>For the truly paranoid</STRONG>
   <P>
   If you are truly paranoid, you can just make the
   <TT>Makefile.configinstall</TT> file and then save, copy,
   and restore all the configuration values yourself.
   <TT>loncaparestoreconfigurations</TT> 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).

   Never never never never never manually install the

   the existing /etc/passwd file).

   <STRONG>Configuration files</STRONG>
   <P>
   Configuration files are automatically saved with the file suffix
   ".rpmsave".  So <TT>/etc/httpd/conf/access.conf</TT> is saved as 
   <TT>/etc/httpd/conf/access.conf.rpmsave</TT>.  You can restore
   the machine-specific configuration information by running
   the <TT>/usr/sbin/loncaparestoreconfigurations</TT>.  However,
   a <B>warning</B> is important here.  If you install an RPM twice
   without restoring your configuration, you will overwrite the
   ".rpmsave" files.

   files, compiled binaries, directories, and links as they should eventually
   occur on the '/' filesystem location.

   <P>
   <TT>loncom/build/make_rpm.pl</TT> is robust (tested over the
   span of months) and, unlike other automated RPM-builders, cleanly
   builds new RPMs without any after-effect of temporary files left
   on the system.  (On the negative side, there are a number of
   LON-CAPA specific customizations inside make_rpm.pl which, for
   the sake of reusability, should eventually be removed).  Two new RPMs
   are generated: LON-CAPA-base-3.1-1.i386 and LON-CAPA-setup-3.1-1.i386.rpm
   (again, never manually install LON-CAPA-setup-3.1-1.i386.rpm).
