Hi Maxim, Thanks for the reply and info.
I don't mind doing the work to find out exactly what is being logged with deep understanding of Guile/Guix's logging mechanism. A bird's eye view while still understanding the low level and commenting on it. It will require some time to do that research and write a good explanation. I'm in no rush so I will try unless someone else gets to it first. Might be good to talk with the person who wrote that logging to discuss the information and concepts involved in the context of guile and guix. all best, jgart
