Environments that use the Custom JumpStartTM method to perform unattended system installations require minimal tuning to suppress the first boot prompts.
A sample script, set_nfs4_domain, is provided in the Solaris 10 distribution media and is located in the ${CDrom_mnt_pt}/Solaris_10/Misc/jumpstart_sample directory. A copy of this script should be modified to set the NFS4_DOMAIN variable to site-specific needs and be called from within JumpStart's finish script. The target system's NFSv4 domain is therefore preconfigured as part of the JumpStart finish phase, and thus suppresses any first boot prompts.
Follow these steps to perform unattended installations:
Create a copy of the set_nfs4_domain script in the same directory as your JumpStart's finish.sh scripts.
Edit the script and set the NFS4_DOMAIN variable to your specific needs.
Edit your finish.sh script and append a call to set_nfs4_domain.
Perform the JumpStart installations as usual.
