If you're a package maintainer and your package already uses xulrunner,

If the rpath is eliminated, how do we know when things really *do* need

gecko-libs 1.9 exports only frozen interfaces so ideally we don't need to rebuild any package unless we move to a completely new gecko (firefox 4 ;-))

I don't find that rationale particularly confidence-inspiring. (Since when did software development proceed "ideally"? ;-)

Are we sure there are no external symbols accessible from public headers that aren't considered "frozen"? Or are we just sure that blessed interfaces are frozen?

I don't like the idea of playing without a net here. soversions are how we track backward compatibility; software that doesn't follow conventions *should* be handled with the kind of caution that is reflected in (for example) an rpath. It's a pain in the ass because it breaks a lot. But it breaks *predictably*. I'm sure I'm as unhappy with the rebuilds as anyone; but I *like* determinism *a lot*.

Do we have any statements of intent from upstream regarding these issues? A commitment to change library names when frozen interfaces change, perhaps?
