Discussion in #ceph-devel today:

< ktdreyer> I was looking into the way that ceph currently bundles a copy 
                  of libs3 as a git submodule
< ktdreyer> was that done because we needed changes that libs3 upstream 
                  wouldn't accept? or upstream was just dying? or just 
                  convenience?
< dmick> dim memory of "the domain was hardcoded"?

[...snip...]

< ktdreyer> Ubuntu has its own libs3 package, but Fedora doesn't
< yehudasa> ktdreyer, libs3 was not part of any distribution
< ktdreyer> yehudasa: if we were to get libs3 into the distros, could we 
            use it?
< yehudasa> ktdreyer, I'll need to check, we made some changes to the 
            library, but some of the stuff that we made went upstream
< ktdreyer> yehudasa: thanks
< yehudasa> ktdreyer, looking at it now I don't see anything essential 
            that went in after my changes were merged upstream. There 
            are some bug fixes there though
< ktdreyer> yehudasa: looking at 
            https://github.com/ceph/libs3/commits/master , I see there's 
            some GNUmakefile changes, plus dalgraff's changes - were 
            those all?
< yehudasa> ktdreyer, there were other changes prior to that, but they 
            went upstream
< ktdreyer> ah good
< yehudasa> we only need libs3 for running rest-bench, btw. Not sure if 
            it's worth the trouble
< ktdreyer> ok, that's good to know
