It sounds like since this series removes dmg from the list of modularized drivers, there is a libbz2 dependency that may get pulled in from the dmg driver. I believe Fam was suggesting moving that part of the dmg driver into its own module (although not modularizing the entire dmg driver). Does that sound like a correct interpretation Fam? I do like the idea, but I'm a little hesitant to put that into this series because I'd like to keep this series fairly simple so that hopefully there doesn't need to be too much more discussion about it. My internship will be ending soon so I'd prefer this series be finished sooner rather than later. Also I don't think anything in this series excludes this idea from being added later if we want. Of course there is always room for discussion, so if there are other thoughts I'm happy to listen. Colin
