FYI, Emacs is now built and tested in FedoraĒs continuous integration testing system, Koschei. Only the Emacs version packaged in each Fedora release are tested, so this isnĒt terribly useful for uncovering new bugs introduced through Emacs development. However, it should help uncover when, for example, compiler or library changes cause trouble. Testing is done by running `make check`. This only happens in rawhide (FedoraĒs development snapshot) for now, but will trickle into stable versions of Fedora as they are released. https://koschei.fedoraproject.org/package/emacs -- Peter Oliver
