Long time, no see

lightdm-1.6.2-1 is there. And so is Xephyr 1.12.4-6.2+b2.
The latter works with the usual procedure. The former does change the procedure a bit. The patch referring to removing stale files does not apply at all. I just don't use it any more... and as far as I know there has been some activity in the lightdm project regarding removing any stale files at runtime. So now only the patch adding the "common-vt" option is required.
Below is what I applied:

diff --git a/src/lightdm.c b/src/lightdm.c

And it works, as of October 5th, 2013.
