Hello Guix, it has come to my attention due to the recent reporting of #45830 and some conversation in IRC, that cups-service-type adds an lp group, which is already defined in %base-groups. Since both share the same definition, this is not too big an issue, but it prohibits us from using a hard error for #45770.
I can currently think of two solutions: Either remove the lp group from cups-service-type or remove it from base-groups. Neither sounds particularly awesome. Perhaps we could also delete identical duplicates before asserting that there are none for #45770, but that sounds like a little much effort. Any ideas how else to solve this? Regards, Leo
