When enabling extended attribute support in a tar file (--xattrs) all extended attributes are stored in the archive, however when the same archive is extracted only the user.* extended attributes are extracted. To have all the extended attributes read and applied on extraction one must also use the '--xattrs-include=*' option. I find this behavior surprising and especially so given that the documentation indicates that "By default, when `--xattr' is used, all names are stored in the archive (or extracted, if using `--extract')"[1].
I'm happy to help working on resolving this issue but it isn't clear to me whether the program or the documentation is incorrect. I've read some of this mailing list's archive but didn't find an explanation as to why restoration of only 'user.*' extended attributes would not be a bug[2].
