I’d forgotten about Myrlyn. I guess I never switched over to it from the older YaST software updater, which does not have the equivalent of ‘zypper dup’. But from what I read now, Myrlyn does, so that is good.
Discover does not, however. Not only does it not do the equivalent of ‘zypper dup’ it does not resolve package conflicts that can arise with external repos.
For anyone reading whose not familiar, on Tumbleweed, ‘zypper dup’ (or the Myrlyn equivalent) is what you need to run periodically to update to the latest snapshot (and being a rolling distro, new snapshots come out anywhere from every day to every few days, depending how the automated testing goes).



Hierarchical taxonomies always run into problems because there are multiple equally valid ways to organize things. Hierarchies are inherently a wrong-headed approach. Subjects are inherently multidimensional. Hierarchies wind up forcing you to stack categorization on different properties on different levels of the hierarchy and it winds up arbitrary which ones you preference over others.
The tendency to reach for hierarchies is a bias we inherit from life in the physical world. A physical object can only be in one place at a time, so we organise physical objects in hierarchies by necessity. Rooms, cabinets, drawers, files. This is not a necessary limitation on computer system but people keep insisting of using them anyway.
