Most of the considerations brought up for medium installation scenarios in Section 2.1, “Deploying up to 10 Workstations” still hold true for large scale deployments. However, with a growing number of installation targets, the benefits of a fully automated installation method outweigh its disadvantages.
It pays off to invest a considerable amount of time to create a sophisticated rule and class framework in AutoYaST to match the requirements of a huge deployment site. Not having to touch each target separately can save you a tremendous amount of time depending on the scope of your installation project.
