Eh? I thought in linux we have competing cdb authors on purpose. For example, how sr decides if a device is writable differs from how ide-cd decides if a device is writable. I thought that the powers that be like linux that way. No? Having multiple cdb authors necessarily means that the cdb's passed thru one kind of transport or another do differ any time the multiple versions of copy-edited authoring code differ. In particular, people designing an unusual device to work with linux have to repeat their work: once for sr, again for ide-cd, and so on. No? Pat LaVarre
