I don't expect to make any final decision on what to do next until after Jessie ships. Meanwhile this list has been helpful in pointing me to possibilities that are worth evaluating. At this time I am particularly interested in three possibilities: (1) Using Jessie with some Wheezy packages to avoid systemd. (2) Devuan. (3) Using Funtoo to build binary packages for internal distro. Despite the effort put into systemd-shim I am concerned that it is continuously churned by the unstable systemd interfaces it tries to emulate. I do not consider it a viable solution. --Mike
