Sandboxing

[mal content]

Hi.

This is mostly hypothetical, just because I want to see how knowledgeable
people would go about achieving it:

I want to sandbox Mozilla Firefox. For the sake of example, I'm running it
under my own user account. The idea is that it should be allowed to
connect to the X server, it should be allowed to write to ~/.mozilla and
/tmp.

I expect some configurations would want access to audio devices in
/dev, but for simplicity, that's ignored here.

All other filesystem access is denied.

Ready...

Go!
