Thanks.  On reflection, I think I'll go via 6.1 (more target practice),
use GENERIC if there's any trouble, then to 6-stable as a smaller step.

Good reminders; this box won't be critical till it's all working ..

Good to confirm.  I haven't so many ports installed that I couldn't
start from scratch if it all fell over, so I can play with ports and
packages till I finally learn how to use all the tools effectively.
