I don’t use NixOS for my home server mainly because of lack of MAC (SELinux or AppArmor). I use Ansible to configure AlmaLinux from package installation to firewall to systemd services.

I use NixOS for desktop and development machines.

Ansible and Nix. Code is the document.

I think Linux enshitifcation will happen when Linus Torvalds is no longer the benevolent dictator. I assume bigtech would add more DRM crap for more usecases etc, regular (unintentional) userspace breaking for desktop users since development would be focused for server/cloud computing etc.
