I did a “dist-upgrade” on my kFreeBSD debian / gnu test machine today, and upon restart, X11 failed to start. :-(
I realize that this debian port is incredibly volatile and experimental, so I don’t want to sound like I’m complaining, just reporting my experience. I’m confident that in good time the problem will be fixed. I had just gotten iceweasel to work on it, so I’m looking forward to getting back to that stage.
