I'm not really sure of the details, but as I mentioned on IRC, 
that commit stopped me from being able to boot. I grafted a new 
version of the Shepherd and reconfigured my system, and when it 
came up my screen was filled with messages complaining that it 
couldn't create things in /dev because they already existed. I 
tested the commits since the previous release and that was the one 
that caused my problem.

I'd like to investigate further, but I have no idea what could be 
causing it. All I have to go on so far is that I think the udev 
service is getting respawned repeatedly, but I don't know why that 
commit would cause that problem. After reverting that commit I 
could successfully boot back into my system and everything is 
working properly again.
