At the time of writing this document, HP is currently investigating
the potential impact to HP-UX released Operating System software
products. As further information becomes available HP will provide
notice of the availability of any necessary patches through standard
security bulletin announcements and be available from your normal
HP Services support channel.

HP Tru64 UNIX/TruCluster Server:

Early Release Patches (ERPs) are now available for all supported
versions of HP Tru64 UNIX/TruCluster Server. 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 recommend
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.
