Emulating NixOS' impermanence module on Fedora Atomic

Jump

  • So, the basic premise of the impermanence module is to flush all state on (re)boot. By default, NixOS is already capable of rebuilding your entire system from the config file(s). The impermanence module simply aids in achieving the desired system workflow for no state without reinventing the wheel. In effect, It's as if you've just done a reinstall and setup everything as you like. But you get to experience this on every reboot. For someone that's perpetually disturbed by state, which has been the case since my Windows-days*, this would finally grant me a peace of mind that I've been yearning for years. So, to answer your question, it would help me get (at least one step) closer to stateless Fedora Atomic without giving up general usability.

  • You would have been right if the entire filesystem were to be immutable. However, for Fedora Atomic, /var and /etc are writable. Thankfully so, as most people wouldn't want a totally locked down operating system. Heck, no general-purpose distro (or OS otherwise) tries to achieve that level of immutability by default.
