[andhow]

Boot To Gecko is not a project to build an operation system.

IIUC, Mozilla is planning to reuse Linux and core components of Android. If anything, I would think Boot To Gecko would be better thought of as a shell around the OS. Using process separation (underway for a while now in the Electrolysis project) bugs/leaks/crashes in Gecko should be isolated and not significantly more disruptive than in normal Firefox.

I think the major value provided by (and work required for) Boot To Gecko will be on creating open standards (in the open) for access to the device so that web platform can be a first class citizen of the device.
