I'm super excited about this talk and I hope I get really good footage 
of it so that I can put up a good clean video of it for others to check out.

 From my experiences with systemd, there has been little truth to most 
of FUD that people were passing around before is hit Ubuntu for the 
first time.  I've found it to be very stable, and it fixed many of the 
service starting issues that I was experiencing with some of my systems. 
  And for one of my projects is also brought with it super easy to setup 
multi-seat systems.  I also haven't experienced it taking over 
everything in my systems.  Pretty much everything that I used to do 
under sysvinit still works under systemd, granted you can get a few more 
bells and whistles if you do it the systemd way, but you don't have to 
(at least not yet).... but that's my experience and there are definitely 
use cases that would require over init systems, but for me, I'm sold and 
can't wait to find out more about some more goodies it brings to the plate.
