This would also be an advantage of this new feature.

To use an external stored environment *only* for development purposes or tests
and to keep the possibility to do so.
The production system should always use a well defined built-in default
environment (but without an error message due to an empty storage which always
looks more like "it works by accident").

No. If the environment is broken (but valid from the checksum point of view)
this new feature wouldn't help.
Repairing a broken environment/barebox is a different issue.

Juergen
