What are you suggesting we do? The kernel has historically had difficulty determining the status of GSS support in user space. One way to remedy this would be to have "systemctl disable nfs-server.service" blacklist the kernel's GSS module, and "systemctl enable nfs-server.service" remove the blacklisting. This mechanism would have to be sensitive to both gssd and svcgssd, of course. -- Chuck Lever chuck[dot]lever[at]oracle[dot]com
