And as I said, the userspace propagation will actually need to turn off in-kernel propagation which fits setting airgroups to 0. johannes --=-+paLlOx76aXM3HpXtx// Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIcBAABAgAGBQJJPYRMAAoJEKVg1VMiehFYI/UQAJF6Rf8iNBYrS3+4ckhdNaDv L3cEk030jiYXrRgn0D9EiVGZFpMmiAXDHlyr5QZFqkub8vwO6WIGYJJuNcRWu5g3 7TLK2ToPCTmiM/DpSrNQjFLCd4Hty+hucAsusgTgMUPmvbUvHL4MX+ZxwyfmiwA1 AadmU4kBBMDI2qSJxHLlTjEMspgRrZaWWqTK6g8kSDbEe2B6tFUC2IPregyGQxat 1z6tAD7gM3K+VzyLh4THeTYGVNgeQVFMohqO76nvQQMRV1Oma7w4Rmjov/4UnvCd xDj9dfhLIg7yTdQtxPbS8p5/cZ1BwSbmHwHOoUHUnzHMGmNYcJdj44qBPB9BYYp3 UzyVgwpp0vZelBXIFaSq1XiN6Bzs+LXTz/aBevFa2vGdcrCbdmSE3d438JXSjOIP HttSAn+GU5t97qLOw5ZGz0enRgO4nRPYDps3nLffW3JU+yzcbdUEYE4vl8hfZSPP ggUaiPSlifrEv90nHrRuuyvLId7IFQPCes0NfnZ8Zto2xx/lDSpmmdWgTLHeAaPk xuG5cgOcfkjLIga3L8xrMrZpe04hsmBkqE1DvTqN3fdwZBvpyhD8Naiu/V9aO5V3 YshUbjjUVTv0yJRkMCRZimVOHDKsU5i8MDbadmxCwUaRgwaL3G0ZiKND/fupyoT2 1aoJM6hzga+gE2xsmYTr =Nw8M -----END PGP SIGNATURE----- --=-+paLlOx76aXM3HpXtx//--
