We are going to have to rebuild all the libraries, that's not an option because of the ABI change. The problem is not to avoid this, but to find a way of doing an online upgrade. The real problem we have to avoid is breaking system tools that are required to perform the upgrade in the intermediate steps. I don't rule out that will require us to pull this trick with some libraries in addition to libc, but I don't think it will be all of them. Just doing libc will probably fix the majority of the issues, though.
