As requested by cjwatson the i386 flavour names are generic and
generic-pae. -server has been removed in Karmic, so the upgrade paths
should be:

Jaunty server --> Karmic generic-pae
Jaunty generic --> Karmic generic

As soon as the ports flavours are integrated, their upgrade paths should
be the obvious choices.

Jaunty 386 --> Karmic 386, etc
