This is actually a bug in ubuntu-release-upgrader. The downloaded wily.tar.gz contains *its own* version of invoke-rc.d, and it's wildly out of date (pre-vivid at least). I extracted the tarball and diffed its imported/invoke-rc.d against /usr/sbin/invoke-rc.d and get http://paste.ubuntu.com/12888661/ -- IOW, all the systemd support is completely missing.
