Installation#

With flakes:

{
  inputs.sessiond.url = "git+https://tangled.org/r0chd.pl/sessiond";
}

Use inputs.sessiond as sessiond in the examples below.

With npins:

npins add git --name sessiond https://tangled.org/r0chd.pl/sessiond --branch master

Import the pinned source in your configuration:

let
  sources = import ./npins;
  sessiond = import sources.sessiond.outPath { };
in
{
  # ...
}

Import the NixOS module:

{
  imports = [
    sessiond.nixosModules.default
  ];
}

or if you're using finix:

{
  imports = [
    sessiond.finixModules.default
  ];
}

Configuration#

Enable sessiond:

{
  services.sessiond.enable = true;
}

To enable the PAM module for another PAM service:

{
  security.pam.services.<service>.sessiond = true;
}

Available options:

{
  services.sessiond = {
    enable = true;
    package = pkgs.sessiond;
    seat = {
      user = "root";
      group = "seat";
    };
  };
}
