Draft: ElementaryOS pantheon desktop w/ systemd
Doesn't get very far yet... The pantheon greeter is totally broken.
lightdm PAM config needs to be adjusted to reference pam_systemd.so instead of pam_elogind.so (maybe we should add a symlink?).
If you make it to the desktop by using the GTK greeter (and choose "secure session" for wayland) then you'll just get a wallpaper and a lot of kernel messages about wingpanel crashing with SIGTRAP.
Haven't debugged further.
