Locating Installed Packages and Variable Data

It is a good idea to follow the packaging recommendations produced by the Linux community -- the recommendations help prevent the cluttering of /opt by code and /var by application data. These recommendations suggest including the vendor and package name in the location of the code and data. As an illustration, consider the following example.

Suppose IBM develops a new application called "abc." The package should ideally be installed in /opt/ibm/abc. The related data should be located in /var/opt/ibm/abc and not simply /var.
