I think it really is abuse of fwcutter. What if you don't want any proprietary firmware at all, but still want an SPROM image? What about distros that do _not_ automatically use fwcutter to put proprietary fw in place for legal reasons? (Which most likely is the majority of distributions). Why create yet another dependency on fwcutter. I thought the long term plan was to get rid of proprietary firmware and fwcutter? Is it really such a big deal for a distribution to include yet another tiny opensource package? If that really is a problem for a distribution, they should just completely stop doing their distro. -- Greetings, Michael. _______________________________________________ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
