You should choose a custom JumpStart installation when you have to install Trusted Solaris software on:
Many hosts.
Particular groups of hosts.
For example, the following scenario would be ideal for performing custom JumpStart installations:
You need to install the Trusted Solaris software on 100 new workstations.
The engineering group owns 70 out of the 100 new workstations, and its workstations must be installed as standalone workstations with the developer software group.
The analysis group owns 30 out of the 100 new workstations, and its workstations must be installed as standalone clients with the end user software group.
These installations would be time-consuming and tedious if you chose to perform an interactive installation on each workstation.
