We could do so, should I provide a proper patch? On the other hand I think this approach is a workaround to circumvent the MTD architecture flaws mostly needed in embedded systems where we control the whole environment. Should we really introduce this switch to the whole bunch of users working with mainline distros on their beagle style HW? I think the user space tool approach is more useful there. regards Andreas Bie=DFmann --IKCdnde46RKgR5j1CfdkxkxTUs0HdWDod Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJSogrGAAoJEHPlkEBPIQBj20MQALfiflIznOyUspyjX0LX+NXi HQoBdeg6tqb28LNp46NZoFU2GSEAGtpn4xyBQIZ9u6M4Ed4a9w0r3djSkR5/n6zD CvMyEPPh3g3Viv/lo9YSzkydYN68CYBiVNOVxfs28lG6JCn7+I3B1qSwznMXYqqd WfjozV8EVPK41JqIsIKv3d0mpVEPCH2ZUGa/nH+CuZaHxOsWp4uKjUs2StQCJs3z tNO6pQBK5IzV1ctKqC5HslDO8iDgGwThQ3PmtG07uV1o30c1jhNEuXTh4sK5SI5s kmFIkfxFbwaTKwF+mz0CjstRpBmYKAv/53kRwswQJjIU+Lf0+FCUA44FZ1FyrnmW fJXlMNMsMjVjq6q6ZyKZsm75fzEalOyFZZKaWE27LJpeCbDAqgHtB+uz2kgqqb2w dS1vRXAnQDXeFKUc9P2371WeqS1pm4ismjeyLqBTtXBWKhoWmlzIZazvFs+FTPb8 dJw+07r2ZDQCkbrSXfYA16yIj2u8nZTXm7lG/nwh0AwJfiRc1xmpNwE7FKf+yfzW ULYnuelVgybrX/3/sIjBsjseJpew/RDM0wP/nK2Wq8jtS3aa5FlFW1PWAUYRsuxd 69pAmKkyb0NasveI1wiGwjmKh6y+k+sy4Uwle1hxdbKD3qLuTSVMdG7/z9QkT27Q a2jHmyVVHLJuziEPtQ6N =/sZU -----END PGP SIGNATURE----- --IKCdnde46RKgR5j1CfdkxkxTUs0HdWDod--
