I forgot another important piece of information (because i lost the original response while trying to reproduce the bug): udev is started in rcS.d, way before elogind, which is in rc2.d. The result is that, at boot, udev clearly logs that it does not detect cgroups, so it will not make its sigkilling spree. But after elogind is started, the cgroups are created. udev really needs to be restarted after that point to have it detect the cgroups and trigger the bug. That, and udev must detect that its parent pid is 1, which can happen quickly when launched by start-stop-daemon --background.
