swap file

Thanks for informing me of the drawbacks of my idea of using the pendrive. I suppose it isn't a good idea seeing as how you only get a limited number of writes to it.

About the  solidstate drives: I guess i have a wish list now:D

Seriously though my dad says they have memory on PCI so I will look into that.... then hesaid he would give  me his computer after he finished digitizing all of his vinyl. It is a Presario with 256M  of RAM and an AMDK7. Hmmmmmmm, presario isn't known for it's Linux friendliness is it.
