What you are describing sounds like plain old debian. Stable thing that you can occasionnally update, perfect for all your server stuff. All my servers run CLI debian (probably won’t be your case as you mentionned some gaming on it too) and I tend to forget about updating them (or even having them to be honnest) due to how stable the damn thing is.

Isn’t it a hacky one person foss project? of course the thing is gonna be dodgy, I’m neither shocked nor worried about it.
