> Flash uses the JumpStart framework. The difference is that Flash lays

> Flash is exceptionally suited to situations where you have to deploy

> package form. Flash is also ideal for situations where you need to
> install a large number of systems with an identical software stack.
> My new JumpStart book has several chapters on using Flash:

> A single archive will suffice.
