Drivers are delivered to customers in packages. A package can be added and removed from the system using a standard mechanism (see the Application Packaging Guide).
Test that the driver has been correctly packaged to ensure that the end user will be able to add it to and remove it from a system. In testing, the package should be installed and removed from every type of media on which it will be released and on several system configurations. Packages must not make unwarranted assumptions about the directory environment of the target system. Certain valid assumptions, however, may be made about where standard kernel files are kept. It is a good idea to test adding and removing of packages on newly-installed machines that have not been modified for a development environment. It is a common packaging error for a package to use a tool or file that exists only in a development environment, or only on the driver writer's own development system. For example, no tools from Source Compatibility package, SUNWscpu, should be used in driver installation programs.
The driver installation must be tested on a minimal Solaris system without any of the optional packages installed.
