Do we even need this code at all? As far as I can tell from the git logs, the idea is to support users who hand-modify config-devices.mak. But do we want to support that? I would think of config-devices.mak as an internal part of the build machinery, and the bit you can edit as a user is the stuff in default-configs/. thanks -- PMM
