The protocol doesn't have explicit support for it, just as NFSv4.0 doesn't in the case of security on /, but we can still support a form of "negotiation" in both cases by doing a linear search through the supported flavors and trying each one. I agree that we should do that. I don't think it necessarily needs to be done *before* any of the other changes that have been discussed, so it could be done as a second step. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
