     4: Subject: Don't use nix-store --add in tests
     5: Message-Id: <fa8c590ff58037c6-0-artemis@nixos>
     6: resolution: fixed
     7: 
     8: inNixedDir calls 'nix-store --add'. This can cause problems, since the
     9: output doesn't get picked up by the Nix garbage collector as a
    10: reference, i.e. we might have derivation A which depends on B and C,
    11: where C is the result of `nix-store --add`. As long as A is "alive", the
    12: garbage collector won't delete B, but it might still delete C since it
    13: doesn't realise that A needs it.
