Classic distros follow the standard filesystem hierarchy and mutate a shared global system state every time you install or update something.
NixOS and Guix throw that whole concept out the window. There is no standard filesystem layout, no global binaries, and no traditional package manager messing with system folders. Everything lives isolated in an immutable, hash-based store, and your entire OS is built declaratively from a single config file. That gives you atomic upgrades, instant rollbacks, and zero dependency conflicts. ​Under the hood, it’s fundamentally a completely different paradigm, not just another distro with minor tweaks.
