Yesterday's replacement of Consolekit by elogind works fine in kernel 4.9.* but not in kernel 4.4.*, as it hangs for about 15 seconds at "starting dbus."
Unfortunately, kernel 4.4.* is the last kernel that works with Xwindows on the (admittedly dreadful) Via VX800 chipset.
Suggestions beyond "learn to live with the boot delay"?
