Tim Steinbach- Sane System Management with NixOS - I Do Declare!- λC 2019

Can you imagine a world in which you’re not worried about OS or package upgrades? Where you can just roll back bad configuration? Package dependencies never collide? Everything is configured in one place? You can have that world TODAY! Be aware: After this talk, you will want to format your laptop. Do you know why your OS has configuration files are all over the place? Or why the binaries on your $PATH come from a wide variety of places? Yeah, me neither. The fact is, it can be painful to find what you are looking for. There is a better way! Binaries rely on libraries. Where are those? And what if I need to update the libraries? Can you ensure the binaries will continue to work? Yes “Reboot your computer to apply the update.” Are you worried? Don’t worry, be happy! The Nix package manager and NixOS—a Linux distribution built on top of Nix—are a declarative way of setting up a system. Package rollbacks are trivial, making bad updates nothing more than a nuisance. Packages are accompanied by their dependencies and statically linked, allowing for multiple versions of the same library or application to live side-by-side. Finally, since the entire system (including installed applications) is configured from a single place, hunting through /etc and ~/.config is finally a thing of the past.
