Indeed, my system does have a really slow disk, so it would not surprise 
me if that contributed to it. Of course that shouldn't matter, but that's 
the only thing I can think it. It would be nice to hear if sirgazil can 
reproduce the fix since I think they were having the same problem on their 
computer.

I agree that fixing is better than removing. Good luck debugging. I'm 
happy to test, but am currently out of ideas.

I'm glad that you took this well :). However, while I'm often sarcastic, I 
wasn't trying to be here. What I was trying to express was that while I'm 
currently running my system with gnome-initial-setup removed doesn't mean 
that I don't appreciate the change to make it present by default. 
Fortunately for me, Guix makes this easy compared to other systems!

Best,
Jack
