I have the following directory structure: ``` $ tree . . ├── files │   ├── a.txt │   └── b.txt └── rockcraft.yaml ``` And in `rockcraft.yaml` I want to organize those two text files, but I make a typo and point both to `etc/newfiles/a.txt`: ``` name: leftover summary: Permissions description: Permissions license: Apache-2.0 version: "0.0.1" base: ubuntu:22.04 parts: default-config: plugin: dump source: files organize: a.txt: etc/newfiles/a.txt b.txt: etc/newfiles/a.txt stage: - etc/newfiles/a.txt - etc/newfiles/b.txt ``` `rockcraft pack` then expectedly fails: ``` $ rockcraft -v pack (...) :: + cp --archive --link --no-dereference . /root/parts/default-config/install Failed to organize part 'default-config': trying to organize file 'b.txt' to 'etc/newfiles/a.txt', but 'etc/newfiles/a.txt' already exists.
