HP Tru64 UNIX Version 5.1B-2 and Higher Patch Kit Installation Instructions (March 2009)

Caution:
As with any system update, entering a Ctrl/c during this phase could leave the operating system
software environment in an inconsistent and nonrecoverable state.
Removing Patches Containing Customized Files
If you use dupatch to remove a patch containing a customized file, messages similar to the
following may appear in the session log file, /var/adm/patch/log/session.log:
- Tru64_UNIX_V5.1B / Network Patches:
Patch 25020.00 - SP04 OSFCLINET540 (SSRT3653 SSRT2384 SSRT2275 ...)
Customization found in ./etc/inetd.conf.
Before the backup was restored, we had saved a copy of this file in:
./etc/inetd.conf.PreDel_OSFPAT02502000540
Please compare ./etc/inetd.conf with this saved copy.
If there are extra customizations you want to keep, you would need
to merge them into ./etc/inetd.conf manually.
./etc/inetd.conf.PreDel_OSFPAT02502000540
can be removed afterwards.
This message warns you to examine the removed patch for any customized files it may contain,
which in this example is the file /etc/inetd.conf. In order to keep those customizations, you
will have to manually add them.
The following are examples of such customized files:
• /usr/var/spool/cron/crontabs/root
• /etc/sysconfigtab
• /usr/var/adm/sendmail/sendmail.cf
Release Patches Do Not Automatically Supersede CSPs
Release patches do not automatically supersede dupatch-based Customer-Specific patches
(CSPs). Any Release patch blocked by a CSP will result in a dupatch message. See “Patch
Installation Blocked by Installed Patch or Subset ” for more information. See the release notes of
the new style patch kits for a list of CSPs that are included in those patch kits. The Patch Summary
and Release Notes document included with Version 5.1B-2 and higher includes a list of CSPs that
were reconciled in the patch kit.
Impact on System Upgrades to Later Versions of Tru64 UNIX
In the presence of patches of layered products, certain procedures used to upgrade a system to
a later version of Tru64 UNIX can lead to inconsistencies among operating system and layered
product objects.
NOTE: After successfully installing a new version of Tru64 UNIX, you should obtain and install
the latest patch kit that is applicable to that version.
Some Patch Kits Cannot Be Removed
You cannot remove a patch kit on systems that have New Hardware Delivery 7 (NHD-7) kit
installed when either of the following conditions exist:
