Hello, I am rather fond of the Libertinus Mono font for Emacs, as I like my Monospace fonts to have Serifs. As others may like the font as well I have created a patch to add it to the fonts package. This being the first patch I have ever submitted to Guix I'm not entirely sure I did everything right, I followed the Submitting Patches part of the manual as close as I could, but I may have made a mistake somewhere, so feel free to correct me where needed. I have included the patch generated by git format-patch as an attachment. Sincerely yours, -Tim Van den Langenbergh
