This helps. It’s not really documented with the other overrides:
https://nixos.org/manual/nixpkgs/stable/#chap-overrides
Seems to be a previous question:
But I did find a reasonable example:
https://nixos.wiki/wiki/Overlays
Using that has gotten me to the type error again I mentioned in the other thread. If I just comment out meta.maintainers then I get:
building the system configuration...
error: value is a set while a list was expected

installApplication.nix:

mv -n "$app" $out/Applications/

meta = with lib; {
description = description;
homepage = homepage;

}
Error seems to happen even if I comment out the overlays that use installApplication.nix (without commenting them out in the system packages).
I also get an error about running out of memory, but apparently Firefox is using 16.8 GB so that’s my next troubleshooting step…
