The Solaris suninstall program mounts the system's file systems on /a. The file systems remain mounted on /a until the system reboots. You can use the finish script to add, change, or remove files from the newly installed file system hierarchy by modifying the file systems that are respective to /a.
Output from the finish script is deposited in /var/sadm/finish.log.
Ensure that root owns the finish script and that the permissions are set to 644.
You can use custom JumpStart Environment variables in your finish scripts. For a list of environment variables, see "Custom JumpStart Environment Variables".
Save finish scripts in the JumpStart directory.
