Flake activation is path-sensitive #127

Closed NobbZ closed 2 years ago

NobbZ commented 3 years ago

I built my simple config using flakes, though when o run the activation script it errors:

[nix-shell:~/nixos-config]$ ./result/activate
Activating linkBinSh
Activating linkUsrBinEnv
Activating installLogin
Activating installLoginInner

Does it activate if you add nixFlakes to the list of packages inside the config?

NobbZ commented 3 years ago

Same error:

[nix-shell:~/nixos-config]$ ./result/activate           Activating linkBinSh
Activating linkUsrBinEnv

Activating installPackages

The relevant part seems to be the final line where it searches for a ~/result, while I run ~/nixos-config/result/activate with ~/nixos-config as PWD.

Probably some pathes hardcoded that shouldn't be?

NobbZ commented 3 years ago

Activation succeeded after I created a symlink ~/result to ~/nixos-config/result

I am not sure why this should not work but the problematic lines are https://github.com/t184256/nix-on-droid/blob/master/modules/build/activation.nix#L131-L137.

Could you add something like the following and post the results?

{
  build.activationBefore.printDebug = ''
    echo "0: $0"
  '';
}

Is resolved by https://github.com/t184256/nix-on-droid/pull/136
