The Patch Kit Installation Instructions and the Patch Summary and Release
Notes documents provide patch kit installation and removal instructions
and a summary of each patch. Please read these documents prior to
installing patches on your system.

The patches in this ERP kit will also be available in the next mainstream
patch kit - HP Tru64 UNIX 4.0G Patch Kit 4.

INSTALLATION NOTES:

1) Install this kit with the dupatch utility that is included in the patch
   kit. You may need to baseline your system if you have manually changed
   system files on your system. The dupatch utility provides the baselining
   capability.

2) The patch in this ERP kit DOES have file intersections with a
   previous ERP for SSRT1-41U, SSRT0742U, and SSRT0759U. Please
   see Superceded Patch list section below.

3) This ERP kit will NOT install over any Customer Specific Patches (CSPs)
   which have file intersections with this ERP kit. Contact your normal
   Service Provider for assistance if the installation of this ERP kit is
   blocked by any of your installed CSPs.

INSTALLATION PREREQUISITES:

You must have installed HP Tru64 UNIX 4.0G PK3 (BL17) prior to installing
this Early Release Patch Kit.

SUPERSEDED PATCH LIST:

This patch kit supersedes the following Tru64 UNIX patch kit:

1) Tru64 UNIX Security Vulnerability SSRT1-41U, SSRT0742U, SSRT0759U

   4.0G T64V40GB17-C0009303-12856-E-20020115.tar

This ERP kit is built so it will install over the SSRT1-41U, SSRT0742U,
SSRT0759U patch or standalone. However, installation will be blocked if any
other patches have been installed that affect the distributed file(s) in
the patch kit.
