You'd theoretically want it to take effect when creating the live image,
which implies in the spin-kickstart's file's %pre. That's a glorious hack,
however.

A cleaner way to do it is to *package* it in in a spin specific package that
gets pulled in by the appropriate spin early in the transaction so it's
there for all services. So, for example, fedora-release requires:

spin-preset

and you have a myspin-release package that provides:

spin-preset.

And you then have some generic-preset package for the DVD install.

Of course, this is back-of-the-envelope design one drink into the evening -
I'm open to better ideas.
