So what I need is: Separate out the fixes and minor changes that have no effect on support or introduce new constraints on future changes. Get those out of the way. Then with what's left, sort out the impact in terms of additional support, testing, constraints etc. Then work out what the options are. E.g. we support multiple lock managers. How do your changes affect each of these, including sanlock? New features should only be available where they are tested and supported: if some combination doesn't make sense or won't be tested properly, don't allow that combination. In extreme cases, use configure settings as the method of control (e.g. if a distro decided it didn't want --node that would need to be a configure option). Man pages need to be correct - if an option doesn't work with some lock manager, it should say that (or not mention it if under configure's control).
