sorry for the comment after this is merged, but how do you use the UI path that this creates?

For me, I have to specify uiDir = "${pkgs.moonfire-nvr}/lib/ui/jhbw1r5q3vsp886vvg72wbgwaypp391x-moonfire-nvr-ui-0.7.7"; to get it to work.

This seems awkward and crucially like it is not a stable file path.

Is this a bug? But then I'm not sure how this was a bug as presumably this wasn't committed without being tried? :S

Same problem. This seems wrong to me as well.

@gaelreyrol Can you clarify if this symlink was intended?

/nix/store/c0v8rfg69c042ck81vbmfhqgmlsbp2jd-moonfire-nvr-0.7.7/lib/ui/n9c8ijzh0ndgp6s5h88ix41wfhfxycpz-moonfire-nvr-ui-0.7.7 -> /nix/store/n9c8ijzh0ndgp6s5h88ix41wfhfxycpz-moonfire-nvr-ui-0.7.7/

Shouldn't it be

/nix/store/c0v8rfg69c042ck81vbmfhqgmlsbp2jd-moonfire-nvr-0.7.7/lib/ui -> /nix/store/n9c8ijzh0ndgp6s5h88ix41wfhfxycpz-moonfire-nvr-ui-0.7.7/

?

Because the path is not stable across updates, it makes it impossible to write a config or NixOS service for it.

I suspect it should be:

    mkdir -p $out/lib
    ln -s ${ui} $out/lib/ui
