The add_drv command accepts a path-name specification for the device_driver parameter. This feature might be removed in a future release.
In the Solaris 9 software, the following warning message is written to STDERR when a path name is specified:
Warning: pathname support will be discontinued in future releases of add_drv.
During the installation process, warning messages that are generated by the use of the path-name specification will appear in the install_log file.
For more information, see the add_drv(1M) man page.
