### Check existing issues - [x] I've verified that this bug isn't described by any existing issues. ### Bug description When a part stages a symlink to another folder in itself, there's no way to `organize:` that away. Even if you unstage the original symlink, the copying process is still stepping on its own toes. ### Steps to reproduce `snapcraft pack` the attached YAML ### Environment Just a normal `snapcraft pack` on Ubuntu. ### snapcraft.yaml ```yaml name: xkb-test base: core26 build-base: devel version: '0.1' summary: Single-line elevator pitch for your amazing snap description: Description grade: devel confinement: strict parts: my-part: plugin: nil stage-packages: - xkb-data stage: - -usr/share/X11/xkb organize: usr/share/xkeyboard-config-2: usr/share/X11/xkb ``` ### Log output ```shell ::
