We can't append symlinks to an attribute group, though. I'd need to create
a lot of struct devices just to get the desired directory hiearchy. And
then each of those "devices" will have their own "power" group, which
really doesn't make any sense for what we're trying to show. Is that
really the right way to do this, or something else I'm missing?
