That's a bit unfair, FC6's installer suggested swap = RAM
when I installed it on a Intel Mac Mini with 2GB of RAM.
(I used FC6 since it 'just works' in the Mac Mini's EFI
environment).

I doubled it manually simply because I remembered how painful
the 2.2-->2.4 move was when the swap requirement became
double the amount of RAM.
