can probably be simplified with something like:

Thank you for pointing that out! I've implemented the suggested simplification.

This comment enhances the safety of recursive deletion in `rm` by introducing two key features to prevent accidental data loss. `--one-file-system`: When specified, `rm` will not traverse into directories that are on a different file system from the one on which the traversal began, this prevents `rm -r` from accidentally deleting data on mounted volumes. `--preserve-root=all`: The `--preserve-root` option is enhanced to accept an optional argument, `all`. When set to `all`, `rm` will refuse to remove any directory that is a mount point. The default behavior (`--preserve-root` without an argument) remains, protecting only the root directory (`/`).

I see the Smack tests are failing in the CI here and it appears that its due to no space left on device. I'm guessing its caused when downloading the arch linux img |
