I got caught out by this not generating hardlinks. At this point it's probably part of our "ABI", so just add a note in the docs. Signed-off-by: Colin Walters <[email protected]>

There was a problem hiding this comment.
Not the maintainer (thanks for the review of my PRs!). I'm also a newb when it comes to a lot of the details of tar implementations and details. Leaving a comment here so you can dismiss/hide it and it won't take up space on the main thread.
- What is the behavior when it encounters hardlinks? Will it copy them like Add doc hint that default is different than
tar#366? Would it make sense to spell out what "never create[ing] hardlinks" means in practice? I would appreciate that info when viewing the docs. - Do you know if that behavior is intentional or accidental? I.e. Could this perhaps be a bug to be fixed rather than a behavior to be documented? Genuine question.
- If it's intentional, could adding a method to the builder like
preserve_hardlinks(bool)be a way forward?
My goal here is to better understand the library and its existing behavior and to explore and understand the possibility of ways we could improve this library or possibly the PR.
