Important Information About Begin Scripts

• Do not specify something in the script that would prevent the mounting of file systems onto /a during an initial or upgrade installation. If the JumpStart program cannot mount the file systems onto /a, an error occurs and installation fails.

• During the installation, output from the begin script is deposited in /tmp/begin.log. After the installation is completed, the log file is redirected to /var/sadm/system/logs/begin.log.

• Ensure that root owns the begin script and that the permissions are set to 644.

• You can use custom JumpStart environment variables in your begin scripts. For a list of environment variables, see Custom JumpStart Environment Variables.

• Save begin scripts in the JumpStart directory.
