Fantastic review!
Thank you so much for this: very clear, very thorough, it scattered all
remaining confusions! I thumb up for a blog post! :D
While I had understood most of it, I was completely ignorant of the separation
between the .drv closure and the output closure. It all makes much more sense now.
I think the documentation of `--gc-keep-outputs` ought to be updated.

I find emacs-guix tremendously useful, I highly recommend you give it a try (the
learning curve is very flat). Any reason why you'd rather not use it?

No, I'm talking total disk usage here. If I ask 5G back, then `df /` tells me
that root has about 3-4G free, it never has the promised amount. Can someone
confirm this? Might be a bug.
