install.log collision

[garrett-hopper]

I should be able to use separate packages instead of the aggregated rust package, right?

In rust-overlay.nix:

  # For each channel:
  #   latest.rustChannels.nightly.cargo
  #   latest.rustChannels.nightly.rust   # Aggregate all others. (recommended)
  #   latest.rustChannels.nightly.rustc
  #   latest.rustChannels.nightly.rust-analysis
  #   latest.rustChannels.nightly.rust-docs
  #   latest.rustChannels.nightly.rust-src
  #   latest.rustChannels.nightly.rust-std

When I try to install multiple:

    latest.rustChannels.nightly.rustc
    latest.rustChannels.nightly.rust-src

I get a collision on the install.log file:

collision between `/nix/store/hy56ymz16hq44n2pbci3hq8mnpkn0q8d-rust-src-1.47.0-nightly-2020-08-22-663d2f5cd/lib/rustlib/install.log' and `/nix/store/0rz0qfkz3avn1fqrlph82biq0n79j1az-rustc-1.47.0-nightly-2020-08-22-663d2f5cd/lib/rustlib/install.log'
