Software Engineer Small-Business (50 or fewer emp.) 9/26/2019 "Manage your entire Linux system configuration using a single language" 4.5/5 What do you like best about NixOS? • One language and syntax to configure every aspect of the system • Dependable and accurate control of system states • Ability to back out upgrades, even if the system is unbootable • Create isolated, disposable environments for trying new packages • Create software build environments with just the dependencies you need • No worrying whether installing some dependency or tool is going to mess up your system Review collected by and hosted on G2.com. What do you dislike about NixOS? • Closed-source binaries are harder to install and keep working • Not everything works all the time Review collected by and hosted on G2.com. Recommendations to others considering NixOS: Take some time to understand the paradigm since it's significantly different from other Linix distros. You can also kick the tyres a bit by using Nix on top of a regular Linux distro, but keep in mind that using Nix to manage the OS itself is a huge step up from just managing packages. Review collected by and hosted on G2.com. What problems is NixOS solving and how is that benefiting you? • Fearless system upgrades! • No accretion of junk over time • A sane software development environment that uses a single paradigm for all languages Review collected by and hosted on G2.com.

DevOps/AS3/C++ Developer Entertainment Small-Business (50 or fewer emp.) 10/18/2017 "NixOS user and NixOS server admin, devops" 5/5 What do you like best about NixOS? - reproducibility and deduplication, and many other benefits from Nix package manager - configuration management united with system configuration - actually, quite fast for deploys - upgrades can be rolled back without fear, because it doesn't manage state - functional language as configuration language. Immutability, referential transparency and laziness are really cool! - good and evolving community - easy to patch packages, easy to create new packages (Nix benefits) - open world module system for configuration, where it is easy to manage dependencies and harder to make errors Review collected by and hosted on G2.com. What do you dislike about NixOS? - poor reflection support (why is disk space occupied, why is this option enabled) - poor stackoverflow community - often you should dive into deep internals of NixOS and Linux to figure out how to fix/overcome problems - has bugs - security updates (and unattended upgrades) exist but are a bad story - project is still in experimental state, so enterprises rarely adopt it - community has not enough manpower - typical NixOS admin should be more proficient than typical Ubuntu admin - doesn't have support for all features from upstream (for example, reloading services instead of restarting is still an open problem) Review collected by and hosted on G2.com. Recommendations to others considering NixOS: Learn Nix language Don't be afraid to dig into NixOS internals Don't be afraid to fork it and modify when in need Review collected by and hosted on G2.com. What problems is NixOS solving and how is that benefiting you? Move system configuration into some central place Managing root servers with many-many services and containers. It's really cool that you can remove some service from configuration and it will be really removed from system - no need to mark explicitly to remove some service. This helped to keep servers in a clean state Review collected by and hosted on G2.com.
