| Subject: pam_systemd: do not set XDG_RUNTIME_DIR if the session's original user is not the same as the newly logged in one
| It's better not to set any XDG_RUNTIME_DIR at all rather than one of a
| different user. So let's do this.

Subject: login: revert lazy session-activation on non-VT seats
Existing applications like gdm already depend on new sessions to get
immediately activated on seats without VTs. Fixes a bug reported as:
[systemd-devel] systemd 208:trouble with inactive user sessions at non-seat0 seats
This patch restores the original behavior. We either need to add a new
flag for session-creation or some other heuristic to avoid activating new
sessions in the future.
