I'm interested in booting-off-flash (i.e. like livecd) for more secure online banking at home.
I like System Rescue CD, but AFAIK it doesn't have the wifi drivers. (These are convenient)
Ubuntu LiveCD has the wi-fi drivers, but also has a lot of stuff I don't need
I'd like a way to save some basic config settings (e.g. wifi SSID and passphrase), so that wifi works upon startup, i.e. without having to re-enter the settings.
What's the best way to 'roll my own slightly-customized boot-from-flash live cd?
