I'm looking to set up a simple internet kiosk in the lobby of a motel. For security, I think it's best if I set up a simple Linux distribution whose only user-accessible program is a browser.
Would it be a good idea to take a distro like Ubuntu, set up a limited user account, and uninstall everything except a browser? It might also be possible to use a minimal VM like Blackbox and configure the browser to start when the computer is booted. Alternatively, I've seen some distros that have already been configured for kiosk use - anybody have experience using one?
How would you recommend configuring the system to discard any changes on reboot? It would be nice to allow the browser to be able to write temp files, but I don't want users to be able to make permanent changes to the system.
What browser would you recommend? Firefox is the traditional choice, but there are some other contenders. I know that Arora and Chromium aren't fully baked yet, but I am a fan of the WebKit rendering engine and I am hoping that it's possible to use somehow.
