FWIW, if these were packages in Debian (and, > presumably, Ubuntu), that would be a severity: serious/release critical bug. I believe this is actually a problem with radosgw statically linking some of the same stuff that librados includes, and not with the librados ABI changes. We need to fix that somehow.. In the meantime, though, setting the radosgw package to require a matching librados2 ought to do the trick. > It'd also be nice to be able to do things like mixing newer radosgw while also > keeping the old librados2 on the system.
