Yes, and I agree that it would be ideal to have the derivations built
prior to system activation -- that way, the activation scripts could be
included in 'show-what-to-build*'.

Yes. You raise another very good reason for why system activation should
be carried out by a single, atomic activation script :)

Regards,
Jakob
