We do not have redundant environment right now.

There have been attempts in the past, but they fell short in flexibility
and/or robustness. Nowadays we normally do not use environment in
products anymore, so this isn't much of an issue.

If you have flash I would consider using UBI for the environment. With
atomic LEB change a robust environment could be implemented fairly
easily.
