Binary diff's have existed for a while ;)

But it is the  same situation for a a apt-get updates on a filesystem
you know exactly what is there: you know what is there, thus you can
upgrade that perfectly without any issues.


One thing to consider with such upgrades though is that one might want
to have "dual-image", but I think that is pushing it a bit.

There is a big reason why people tend to state "do not turn off the
device while upgrading".

Noting that CHIP has a boot repair mode:

Thus in the case of a 'wrong flash', we could have a tool that just
flashes it that way as a way of recovery ;)
