If either of those files is missing, then rpc.svcgssd needs to run. In one case, the gssproxy daemon isn't available for some reason. In the other case the kernel cannot make use of it. Is that not correct? That is exactly the rule that I (tried to) encode in the service file with these two conditions. NeilBrown
