My computers and servers (mostly nix) configuration

Options

# in a NixOS module
{
	local.ports."<name>" = 4242; # Shorthand
	local.ports."<name>" = {
		number = 4242;
		string = "4242"; # Read-only
		public = true; # Opens firewall depending on tcp/udp value
		tcp = true;
		udp = false;
	};
}

# in a Home Manager module
{
	local.flags = {
		onlyCached = true; # dictate if you prefer to use cached pkgs
		useZen = true; # use the Zen fork or vanilla Firefox
	};
}
