hello, I use nixos-rebuild to deploy my remote nixos like this:
nixos-rebuild switch --fast --flake '.#router' --target-host root@192.168.123.176 --build-host root@nixbuilder
but i have a custom module config like this:
{ lib, config, pkgs, ... }:
with lib;
let
cfg = config.services.ad-upstream;
in
{
options.services.ad-upstream = {
enable = mkOption {
default = false;
description = "Enable AdguardHome upstream service";
};
path = mkOption {
default = null;
type = types.nullOr types.path;
description = "Path to upstream.sh";
};
};
config = mkIf cfg.enable {
systemd.services.ad-upstream = {
description = "AdguardHome upstream service";
after = ["network-online.target"];
serviceConfig = {
ExecStart = cfg.path;
};
};
systemd.timers.ad-upstream = {
description = "AdguardHome upstream timer";
after = ["network-online.target"];
wantedBy = ["multi-user.target"];
timerConfig = {
OnCalendar = "*-*-* 5:00";
Unit = "ad-upstream.service";
};
};
};
}
and module config defined in the configuration.nix :
services.ad-upstream.enable = true;
services.ad-upstream.path = ./upstream.sh;
the ./upstream.sh and the upstream.nix (module) under my configuration.nix directory.
we know that when nixos-rebuild with flake, it will copy the current directory to the /nix/store/xxxx-source, but after i run “nixos-rebuild” to deploy remote machine, the nix/store/xxxx-source not on the target machine. so the services.ad-upstream.path = ./upstream.shconfig will broken because of ./upstream.sh not exist.
any one have idea about this case?
the ad-upstream.service content, and the ExecStart path not exist.
