Driver Packaging

The normal delivery vehicle for software is to create a package that contains all of the software components. A package provides a controlled mechanism for installation and removal of all the components of a software product. Developers can utilize the driver actions in the Image Packaging System (IPS) to perform tasks while packaging the driver. Refer to the following documents for more information:

In prior versions of Oracle Solaris, the SVR4 packaging system was used, which required including postinstall and preremove scripts in the package to run add_drv(1M) and rem_drv(1M) commands. Existing driver packages using these commands may still be installed on Oracle Solaris 11.
