 > 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.
