I thought about this again.

I would find this message more useful from the new, updated barebox
rather than from the barebox that does the update. This way we could
also see the message with offline updates when for example a SD
card has been updated on an external host. Also we would have more
freedom to react on an outdated environment in the next steps. We could
for example make it configurable to completely ignore an outdated
environment or just to issue a warning message.
Doing this should be fairly simple, we could store the barebox version
in a nv variable and compare the variable with the current version
during startup.

What do you think?

Sascha
