This is a second attempt at firmware grouping so we can have dracut only pull one firmware into the initramfs instead of a bunch of legacy ones. v1 got derailed when it was pointed out that ordering isn't consistent in modinfo with C to sections, so that plan no longer was feasible. This was the simplest next best option, it keeps the group tags, and adds a new list of acceptable firmwares. New dracut will ignore legacy firmware in favour of the list, old dracut will just read the legacy info lines. This is ugly because it requires duplication, but I can't think of a nice way beyond horrible unscaleable C preprocessor tricks to make it nicer. Dave.
