/ and swap sizing (was: Fresh install Kubuntu 13.10: how best...)

[Cody Smith]

the max I use for swap is roughly 500mb more than the available ram (I.E.
8gb RAM, 8.5GB swap), never seems to hurt to have a little more swap than
RAM, but yet, I have plenty of storage (1.5TB total), so I'm not sure how
doable that is in lower storage systems.
