             HP TRU64 UNIX

             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.

          http://www.support.compaq.com/patches/whats-new.shtml

        After completing the update, HP strongly recommends that you
        perform an immediate backup of your system disk so that any
        subsequent restore operations begin with updated software.
        Otherwise, you must reapply the update after a future restore
        operation. Also, if at some future time you upgrade your system to
        a later patch version, you may need to reapply the appropriate
        update.
