Actually, what would be even a better idea is if we made sure we save 
nothing to the root file system. This is fairly common practice with 
embedded devices (where you usually use the root file system as a 
cramfs/squashfs image, which is mounted read only).

The main advantage of the single file notion is an upgrade path that is 
smooth. With a single file filesystem you don't get partial upgrades and 
other %@#$@!# that tends to screw up the end user. It is not as fun for 
developers, because changing anything requires going back to the dev env 
and regenerating the image, but it is much more end users friendly.

Maybe for the consumer edition?
