What I really want is a really stable base OS that's managed totally separately from the individual packages I install. It's the experience one gets with MacOS + Homebrew and it's way better than an "... and the kitchen sink" distro that manages your kernel and basic interface-providing software with the same tool & process that installs and updates Super Tux. (yes I know there are ways to use another package manager on a given Linux distro, even homebrew, but I'd rather see a strong distro built around that idea, not even trying to provide every-friggin'-thing in the distro's software repos)
