### Bug Description Files or directories seem to disappear if an organize key is an empty string. I can't find the pattern by which the file disappears, but pretty consistently there is at least one missing file/directory. They either don't make it into the install directory or are removed during the organize process. ### To Reproduce Consider the part YAML below. When used as-is, the expected behaviour occurs: ``` (craft-parts) lengau@ratel:~/Work/Code/craft-parts$ python -m craft_parts prime INFO:craft_parts.executor.executor:Installing build-packages Execute: Pull a Execute: Overlay a Execute: Build a Execute: Stage a Execute: Prime a (craft-parts) lengau@ratel:~/Work/Code/craft-parts$ tree prime prime ├── my-dir │   └── subdir-a │   └── file └── my-file 3 directories, 2 files ``` When organizing `'*'` to `''`, it works as expected as well: ``` (craft-parts) lengau@ratel:~/Work/Code/craft-parts$ python -m craft_parts clean Clean all parts. (craft-parts) lengau@ratel:~/Work/Code/craft-parts$ python -m craft_parts prime INFO:craft_parts.executor.executor:Installing build-packages Execute: Pull a Execute: Overlay a Execute: Build a Execute: Stage a Execute: Prime a (craft-parts) lengau@ratel:~/Work/Code/craft-parts$ tree prime prime ├── my-dir │   └── subdir-a │   └── file └── my-file 3 directories, 2 files ``` However, when organizing from an empty string, a file goes missing: ``` (craft-parts) lengau@ratel:~/Work/Code/craft-parts$ python -m craft_parts clean Clean all parts. (craft-parts) lengau@ratel:~/Work/Code/craft-parts$ python -m craft_parts prime INFO:craft_parts.executor.executor:Installing build-packages Execute: Pull a Execute: Overlay a Execute: Build a Error: Failed to copy '/home/lengau/Work/Code/craft-parts/parts/a/install/my-file': no such file or directory. (craft-parts) lengau@ratel:~/Work/Code/craft-parts$ tree parts/a/install/ parts/a/install/ └── my-dir └── subdir-a └── file 3 directories, 1 file ``` If you comment out the creation of `my-file`, then `my-dir/subdir-a/file` goes missing instead: ``` (craft-parts) lengau@ratel:~/Work/Code/craft-parts$ python -m craft_parts clean Clean all parts. (craft-parts) lengau@ratel:~/Work/Code/craft-parts$ python -m craft_parts prime INFO:craft_parts.executor.executor:Installing build-packages Execute: Pull a Execute: Overlay a Execute: Build a Error: Failed to copy '/home/lengau/Work/Code/craft-parts/parts/a/install/my-dir/subdir-a/file': no such file or directory.
