Not quite. The new files use a different implementation of a similar API
which doesn't generate any uci calls directly anymore. Instead, an
intermediate file - /etc/board.json - is emitted, which gets used to
generate the default config in a generic way.

Please test the current code, it should have a bridge automatically
without any changes to the existing scripts.
