By default, tar will not include any extended attribute (xattr) when creating archives, and thus will not store capabilties either (as they are stored in the xattr 'security.capability'). Using option --xattrs is enough to create a tarball with all the xattrs attached to a file. However, extracting all xattrs from a tarball requires that --xattrs-include='*' be used. This is not symetric (but on purpose, as per the documentation), and so is confusing to some. So, we use --xattrs-include='*' to create the archive, so as to be explicit that we want all xattrs to be stored. Signed-off-by: "Yann E.
