The following information is important to know about finish scripts:
The Trusted Solaris installation program mounts the workstation's file systems onto /a. The file systems remain mounted on /a until the workstation reboots. Therefore, you can use the finish script to add, change, or remove files from the newly installed file system hierarchy by modifying the file systems respective to /a.
Finish scripts should be owned by root and have permissions equal to 644.
