Ouch, indeed.

Probably. Same for Xfce I guess?
While at it these GNOME and Xfce services should probably do everything
needed to get a full-blown GNOME/Xfce environment.

OK, interesting. Same thing with the power-off button in Xfce/GNOME, I
guess?

What about adding a ‘gnome-session-service’ and an
‘xfce4-session-service’, each of which would extend polkit (the latter
would also pass the Thunar policies)?
Eventually, we could change the SLiM service to be extended by these two
things.

OK!
