This is a very simple plymouth theme for nixos containing a static image of the nixos logo.
To install it, you would add this to your nixos configuration file :
let
redflake-plymouth-src = pkgs.fetchFromGitHub {
owner = "Red-Flake";
repo = "redflake-plymouth";
rev = "master";
sha256 = "";
};
redflake-plymouth = pkgs.callPackage redflake-plymouth-src {};
in
{
boot.plymouth = {
enable = true;
themePackages = [ redflake-plymouth ];
theme = "redflake-plymouth";
};
}
