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.
In prior releases, the /etc/.NFS4inst_state.domain file was created by the sysidnfs4 program. This file would suppress the prompt for an NFSv4 domain name during installation. This file is no longer created. Use the sysidcfg keyword, nfs4_domain, instead.
