 ``CVMFS_XATTR_PRIVILEGED_GIDS``. Extended attributes to which 
 this should apply are listed in ``CVMFS_XATTR_PROTECTED_XATTRS``.
 Note that those attributes must be listed in their full name, e.g. ``user.fqrn``,
 ``user.rawlink`` or ``xfsroot.rawlink``. Most of the extended attributes
 will have the prefix ``user.``. If uncertain, they can be looked up in the source
 code of ``cvmfs/magic_xattr.cc``.
