nixFlakes wants itself in the target store when building from a flake with --store

[vikanezrimaya]

$ sudo mkdir -p /mnt/test
$ sudo mount -t tmpfs tmpfs /mnt/test
$ nix build --store /mnt/test git+https://gitlab.com/vikanezrimaya/nix-flake#nixosConfigurations.maria.config.system.build.toplevel --extra-substituters auto?trusted=1
error: path '/nix/store/1a5hpb0ya1svwxdsny23ra5y75w3cnj6-nix-2.4pre20200403_3473b19' is not valid

This is how nixos-install worked previously (except no flakes! they weren't invented yet). I expected it to work the same with flakes. I was recommended to file an issue when telling this story in IRC.

Copying nixFlakes to the target store with nix-store --export $(nix-store -qR /nix/store/1a5hpb0ya1svwxdsny23ra5y75w3cnj6-nix-2.4pre20200403_3473b19) | nix-store --store /mnt/test --import is a suitable workaround.

Probably related:

$ nix copy --to local?root=/mnt/test $PWD#activationPackage.maria
warning: Git tree '/home/kisik21/Projects/vika-flake' is dirty

Interesting. Looks like this is fixed, therefore closing.
