Project mention: Tar files made in macOS generate "xattr" errors when expanded in Linux | news.ycombinator.com | 2026-05-03
Per this 2018 page, GNU tar seems to work with SCHILY.* encoded xattrs, but not LIBARCHIVE.* ones:
* https://mgorny.pl/articles/portability-of-tar-features.html#...
* Via: https://github.com/mxmlnkn/ratarmount/issues/145
bsdtar ≥3.7.2 apparently adds both types to its files for maximum portability:
* https://github.com/libarchive/libarchive/pull/691/files#diff...
AFAICT, bsdtar will default to "ustar" format, but will auto-switch to "pax" if needed.
