# Fedora CoreOS 8 Hacker News commenters recommended Fedora CoreOS and 4 criticized it, November 2025 to November 2026. It was recommended in 6 of 13 months. **Verdict:** Recommended for servers that update themselves and run containers with little upkeep, and config kept in one place. Critics say Ignition-based setup is too involved for one-off systems. ## Why people recommend it - Immutable OS with safe A/B updates (2 comments): "this kind of management seems ideal, A/B safe testing for boot" ([source](https://news.ycombinator.com/item?id=48916727)) "FCOS Atomic. Completely agree. Immutable host." ([source](https://news.ycombinator.com/item?id=48933844)) - Low upkeep, predictable operation (2 comments): "silently and successfully auto-updated both the OS and the service container for years with no intervention" ([source](https://news.ycombinator.com/item?id=49504326)) "The predictability and drop in toil is so nice." ([source](https://news.ycombinator.com/item?id=46581363)) ## What people warn about - Involved setup, many moving parts (3 comments): "the recommended method to configure the system with ignition files and one shot systemd units to be too involved for making a one off system" ([source](https://news.ycombinator.com/item?id=47481341)) "multiple moving parts all configured independently? CoreOS, Terraform and a dependence on Vultr thing" ([source](https://news.ycombinator.com/item?id=46581855)) "it has a lot less bureaucracy than something like CoreOS" ([source](https://news.ycombinator.com/item?id=47897502)) ## Alternatives hackers recommend - [SmartOS](https://hackerapproved.com/p/smartos.md): 20 recommend - [Red Hat Enterprise Linux subscription](https://hackerapproved.com/p/red-hat.md): 16 recommend - [IncusOS](https://hackerapproved.com/p/incusos.md): 15 recommend - [YunoHost](https://hackerapproved.com/p/yunohost.md): 7 recommend ## Cite as Hacker Approved, "Fedora CoreOS", https://hackerapproved.com/p/fedora-coreos/ (counts from 1,795,640 Hacker News comments, November 2025 to November 2026).
