 - Certain OpenTelemetry instrumentation will not work with Bun, because Bun does not support Node's `register` hook. This means that some libraries that rely on this hook will not work with Bun.
 - If Bun is installed via Homebrew (e.g. `/opt/homebrew/bin/bun`), you may see an `ENOENT: spawn /Users/<you>/.bun/bin/bun` error because the CLI expects Bun at the default install path. **Workaround:** create a symlink:
   ```bash
-  ln -s $(which bun) ~/.bun/bin/bun
+  mkdir -p ~/.bun/bin && ln -s $(which bun) ~/.bun/bin/bun
   ```
