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.
