Layered products and TMPDIR environment variable

The default location for application temporary files is in the /tmp directory of the root filesystem. The TMPDIR environment variable is typically used in shell programming to override this setting. If TMPDIR is set to a location outside the root filesystem, it might interfere with the installation of layered products (such as the Virtual Disk Manager, VisionFS, and so on). The most common symptom of this problem is deletion of the mdevice(F) file.

When installing any layered products, ensure that the TMPDIR environment variable is not set or is set to a directory on the root filesystem partition.

Optional Services upgrade from Release 5.0.4 and later

Some documentation for products on the Optional Services CD-ROM might refer to upgrading Optional Services from SCO OpenServer Release 5.0.0 or 5.0.2. Upgrades of Optional Services products are only supported from SCO OpenServer Release 5.0.4 and later.

Context-sensitive help and online documentation

Context-sensitive help and online documentation for any given technology is normally included as a documentation package within that technology. If you choose not to install or subsequently remove the documentation package, you will not have access to help or online documentation for that technology.

Online documentation for some technologies is bundled with a related technology. Therefore, if you choose not to install a documentation package or remove one later, you might also be removing the online documentation for another, related technology.

The online help for scohelp(XC) (Help on Help) is available only if the Graphics documentation package is installed.

If third-party software does not install, change rel= value

If a third-party software product will not install because the base operating system (or a component of it) is the wrong release, change the rel= value in the appropriate perms file from rel=5.0.6 to rel=3.2.4. This is because some custom-installed third-party products check this value before allowing the installation to proceed. Check with the software vendor before trying this, as certain packages are kernel-dependent. You must change the line back to rel=5.0.6 after installing the software product.

Ignore netconfig message at end of NFS installation

The netconfig utility runs automatically when NFS® is installed on SCO OpenServer systems. Disregard the screen message at the end of the installation script that directs you to run it again.
