Following is an example of a prototype ﬁle for a driver add-on package.

For more information, refer to the prototype(4) manual page.

postinstall 14

The following steps should be performed in a postinstall script to install a DSP:

1. Change directory to /tmp/xyzzy, where the DSP ﬁles were installed.

2. Execute idinstall -a and pass it the DSP name. This creates the

needed directories and moves the DSP contents to the appropriate loca-

tions. If the idinstall -a fails, the package was already installed.

3. If the DSP has already been installed, idinstall -u command is used

to update the package, using the ﬁles from the DSP.

NOTE

DSPs should always use the idinstall -P option. This way

all the ﬁles installed are recorded in the contents ﬁle.

4. Run the idbuild command without any options to create a new UNIX

system kernel when the system is rebooted.

5. removef any /tmp ﬁles installed.
