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.
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.
For the Solaris 10 release, a sample JumpStart script, set_nfs4_domain, was provided on media to prevent being prompted during a JumpStart installation. This script suppressed the NFSv4 prompt during installation. This script is no longer required. Starting with the Solaris 10 5/09release, use the sysidcfg keyword, nfs4_domain that suppresses being prompted. The set_nfs4_domain script no longer works to suppress a prompt.
If you have non-global zones installed and the new nfs4_domain keyword exists in the sysidcfg file, the first boot of a non-global zone sets the domain. Otherwise, the Solaris interactive installation program comes up and you are prompted to provide a domain name before the boot process completes.
