Changing (guix build utils) is an extreme case, but pretty much. I keep a TODO list of things I want to do on that branch, and once it gets big enough, I try to implement all at once before starting the Big Rebuild. Then go do something else until a node in the graph fails to build. Berlin typically has substitutes all the way up to 'guix', so it's "not that bad" unless you are changing the really low layers. > Cheers, and sorry for the mishaps! No worries, and sorry for the angry comment. :-)
