[systemd-devel] How soon after login can I rely on systemd --user having reached sockets.target?

Ok, and login off would just be something like 'systemctl stop gnome.target'?

I sometime login from the same seat multiple times (to test my X settings).
But I agree Xephyr would probably be better for this case.

I could imagine having several virtual machines that connects via ssh -X to
the main computer to launch graphical sessions (so that there is no need to
install it on the vms); in this case there would be a need to start the
same target but with different displays. And the solution I outlined on my
preceding mail using instances target templates work very well (and it does
since a long time, I was very impressed when I tried it and it worked out
of the box); but having 'hooks' on logind would help a bit.

But this is not really an important feature request for me, it was just an
idea in passing.
