The longer I use computers the more I think having an OS-core plus separated user-applications is the way to go. As user I don't care/think a lot about the core, it should just work. Apps should be totally isolated from the base system and be up-to-date. Updating the base should never impact apps, updating apps should never break the base system. Right now I use openSUSE Tumbleweed[0] and Guix[1] for applications. This gives me an up-to-date OS with the ability to rollback OS updates (thanks to openSUSE snapper and btrfs). Guix is a functional package manager with rollback support & reproducible builds, which allows you to have multiple versions of the same library installed so that different applications can make use of them. The above combination solves a lot of problems traditional packaging systems have. I also follow to some extend the Snap[2] packaging world. I like the security idea Snap brings to the table, but right now the snap thing is still work in progress.
