If you're wondering why #concourse_ci `fly set-pipeline -p ...` is suddenly showing a diff with embedded "\n", on your multiline YAML then it's probably because you have trailing whitespace.
```yaml
- |
export METAL_ENV=native
tar xzf fsfm/*.tar.gz --strip-components=1 -C fsfm/
```
```diff
- - "export METAL_ENV=native\ntar xzf fsfm/*.tar.gz --strip-components=1 -C fsfm/\ntar
+ - |
+ export METAL_ENV=native
+ tar xzf fsfm/*.tar.gz --strip-components=1 -C fsfm/
```
