So I'm kinda liking the idea of a #Declarative OS - that is, one where I can edit a config file (or whatever) to indicate the basic system setup, apps, gsettings (since I'm a Gnomie) and so on. Then hit "Update" or "Deploy" or whatever, reboot, and there's the system, as specified.
THEN... I can take that file over to another computer and BOOM, same setup, same apps, same basic desktop setup, etc.
#BlendOS does this with an easily editable yaml file. #NixOS does this with a .nix file that is significantly more complicated, but also more powerful.
Anyone know any other OSes like that?
