Description of Problem:
While doing an upgrade from RC1 to RC2, the installer prompts me to create
a swap file. I had previously created a swap file in RC1, and this went
undetected, as bext I can see.
While an upgrade from RC1->RC2 is unsupported, the installer should be able
to detect and existing swap file in /etc/fstab on upgrade, (Or, if it does,
it doesn't say so!) and not prompt to create a new one.
you needed even more swap, it did the right thing.
