-------------------------------------------------------------------------
Added by putting in /sites/XFS/Updates/
-------------------------------------------------------------------------
The XFS-ized RHELv3 kernel built by the SGI folks (Eric Sandeen) and related
packages.  The xfs-modules package has been merged back into the kernel RPM
so there it is no more.  This enables the use of this kernel as a BOOT kernel
to install on XFS formated system disks (/, /usr, /var, etc.)

-------------------------------------------------------------------------
Anaconda needed to be modified to enable formating the system disks with XFS.
-------------------------------------------------------------------------
Anaconda

	anaconda-9.1.2-2.7.SL.XFS.i386.rpm
	anaconda-runtime-9.1.2-2.7.SL.XFS.i386.rpm
-------------------------------------------------------------------------
These Java RPMS are not installed by default as /sites/example/base/comps* 
does not include them.  They can be installed via "yum" after
the system is rebooted.
The XFS-release is installed by default by adding it to /sites/XFS/base/comps*.
--------------------------------------------------------------------------
Java

        j2sdk-1.4.2_05-fcs.i586.rpm

	XFS-release-3.0.1-7.i386.rpm

	Contains /etc/redhat-release which defines release name.
----------------------------------------------------------------------------
Modifed by putting in /sites/XFS/Updates/
-----------------------------------------------------------------------------
Mozilla

	The latest stable release of mozilla was 1.7.2.  It was decided to
	include it because of it's features, such as stability and a
	spellchecker.  All of it's devel rpms were put into notsupported.

		mozilla-1.7.2-0.2.0.EL.i386.rpm
		mozilla-chat-1.7.2-0.2.0.EL.i386.rpm
		mozilla-dom-inspector-1.7.2-0.2.0.EL.i386.rpm
		mozilla-js-debugger-1.7.2-0.2.0.EL.i386.rpm
		mozilla-mail-1.7.2-0.2.0.EL.i386.rpm
		mozilla-nspr-1.7.2-0.2.0.EL.i386.rpm
		mozilla-nss-1.7.2-0.2.0.EL.i386.rpm

-----------------------------------------------------------------------------
Installer changes
-----------------------------------------------------------------------------
It uses kernel-BOOT-2.4.21-15.EL.sgi3.i386.rpm as the installer kernel by
putting it in /sites/example/Updates/ .

The gui final install screen suggests that you go to www.cern.ch/linux for 
support:-)(Just a example)
This was done by getting the /iw/congrats_gui.py file from the anaconda SRPM
and modifying it and putting it in /sites/example/RHupdates/iw/ .  This is
only a example of changing the installer.
