Actually, I am not sure that is true any more.

For me with systemd installed and a couple of desktops

 apt-get install sysvinit-core elogind libpam-elogind libpam-elogind-compat

doesn't remove anything other than systemd et al.

Obviously the systemd prerm complains, but you can work around that with "rmdir
/run/systemd/system" first which circumvents the prerm check. Obviously you need
to reboot immediately.
