        Yet Jessie is already frozen, so I guess we may see Debian 8
        released in the first half (if not quarter) of 2015.

        Personally, I’d suggest retaining GnuTLS 2 support until a month
        or two after that at the least.

        Yes, although I’d rather question the necessity of building
        Emacs ‘master’ on an LTS GNU/Linux system.  If the intent is to
        use the last decade’s versions of Libc and Coreutils, – why
        Emacs has to be newer than that?

        Especially given that the older versions of the system, when
        necessary to support legacy software, could be just as well be
        run in chroot(2) environments.  (Or even be entirely “virtual.”)
