I've got a new homeserver/NAS (Network Attached Storage), previously I was using some Raspberry Pis, but I've wanted for a while a low power board that has SATA ports for attaching hard drives and one that could run GNU Guix, and the ZimaBoard 2 looked like it might be a good option.

A cool thing about Guix (and probably functional package managers in general) is, that derivations form a directed acyclic graph, which means that all packages with their dependencies or system configurations can be represented as such. Another, even cooler, thing is, that Guix provides a graphing…

I've raised a few PRs against the Guix Codeberg repository recently, and each time I've done so with Forgejo's AGit workflow. This workflow is pretty nice, and allows me to raise a PR entirely from within Emacs. To do that, I've been using this code in my Emacs config to add an extra option to the…
