   Early Release Patches (ERPs) are now available for all
   supported versions of HP Tru64 UNIX. The ERP kits use
   dupatch to install and will not install over any
   Customer Specific Patches (CSPs) which have file
   intersections with the ERPs. Contact your normal support
   channel and request HP Tru64 services elevate a case to
   Support Engineering if a CSP must be merged with one of
   the ERPs.

   Please review the README file for each patch prior to
   installation.

After completing the update, HP and Compaq strongly
recommends that you perform an immediate backup of
the system disk so that any subsequent restore operations
begin with updated software. Otherwise, the updates must
be re-applied after a future restore operation. Also, if
at some future time the system is upgraded to a later
patch release or version release, reinstall the
appropriate ERP.
