These are the slides from my FOSDEM 2016 talk ElectroBSD – Getting a reproducible BSD out of the door.
Currently the slides match the ones I used for the talk, but I will probably polish and extend them in the future and transcribe the Q/A at the end of the talk once the video is up (provided the recordings aren't lost again).
