You're saying booting with the same kernel but kdbus not compiled in works?

This is triggered by running through pam from outside the gfx-session
but on a shared VT. It's not directly related to kdbus, though. It's
fixed in systemd-git. As a workaround, you can remove pam_systemd from
the sudo/su pam config.
