If your system is running the Solaris 8, Solaris 8 6/00, Solaris 8 10/00, Solaris 8 1/01, or Solaris 8 4/01 operating environment and you want to apply patches released in the Solaris 8 7/01 operating environment without losing patches you previously applied to your system, install the Solaris 8 MU5. Patches applied using the MU5 can be backed out.
If your system is running the Solaris 8 operating environment, or a Solaris 8 Update release, and you want to fully upgrade to new features and hardware support, install the Solaris 8 7/01 operating environment. The patches applied by installing the Solaris 8 7/01 operating environment will replace any previously installed Solaris 8 patches and cannot be backed out of the release.
Maintenance Updates are primarily designed to update the Solaris operating environment to a known, tested patch-level. If you want to apply a particular patch, and only that patch, do so through your normal support channels.
The name of this product is Solaris 8 MU5, but code or package path names might use Solaris 2.8 or SunOSTM 5.8. Always follow the code or path as it is written in this document.
