Currently on Fedora Silverblue. I think I'm settling there for a base system/local hypervisor. Tried NixOS but, as someone who has been Linuxing and programming for over a decade, I don't think it is for me (I don't like the syntax or need for a DSL - give me a tool that uses a standardized language like JSON or YAML, not one that forces me to use a language that is of no use anywhere else - not to mention the garbage documentation; if the Getting Started docs don't result in a system that is functional including a networking stack, it is insufficient and no, Discord is not documentation).
