+*** install nix configuration file
+I wish I could do this with a nix-like thing, but sadly, there are several
+complications.
+- for MacOS, this is nix-darwin.
+- for Ubuntu, there is nothing that can do it.
+- There _is_ a way to do something similar with home manager, but it sets the
+  _user_ nix settings, _not_ the system settings. This is not overly surprising,
+  but it does mean that it can't be the sole solution for setting
+  configurations, if you need to set up caches/substituters.
+  At the very least, I would need some *other* way besides home manager to
+  sepecify that my user is a trusted user. But, then, there becomes a question
+  of bootstrapping (nix settings needed before home manager ever runs), so I
+  think its overall easier to just hack a thing with bash.
