Was on the phone and only quickly looked up the latest version. So I only updated to 40, not rawhide.
Sure Gentoo had dependency resolution. Does Gentoo still have use flags? Because that makes dependency resolution much hardere It’s not enough to know the dependeicies, you also have to know all the use flags you dedend on. And if a maintainer adds a use flag for a feature you depend on, you have to add that dependency as well or people who disable that flag break with your package.
I’d be surprised if gentoo was considered stable, if you make heavy use of use-flags - if they still exist.
edit Maybe your “dependency resolution” is a new automatic thing that identifies dependencies including use flags automaticallt? It was automatidally done, only if the maintainers put the right stuff in their ebuilds.
