Hi Stefan, sorry in advance for (very) short response due to time constraints on my part.

I wrote a blog post with possible workaround some time back, hopefully it will serve in place of longer response: https://wolfsden.cz/blog/post/what-goes-into-guix-shaped-hole.html Hope this helps, Tomas -- There are only two hard things in Computer Science: cache invalidation, naming things and off-by-one errors.
