I think it was not the question that it should be locked so everybody have to install it. It was more, that in a default installation hdparm should be installed. And disable udma for cdroms was a bad thing. It is not just needed for viewing dvd. Burning cd's should never ever take 80% of the CPU !! So disabling dma and don't install hdparm IS a bug. At least the user should decide and not the dma for cdroms silently dropped. > to watch dvds, you may prefer having an x server and a good video > card, but you don't need them, you can go with libaa for rendering. > > recommendation != absolute requires right but 'absolut requires' nobody spoke about.

The question for me is: why was this done ? Are there so many buggy cdroms out there, that it causes more problems then not ? And why only disabling it then hdparm is installed ? It is far from logical for me. I had countless people with this cdrom-problem.
