Issue

Documentation says that /opt/cni/config is default configuration path; however if it is not explicitly set, the fingerprinter returns client.fingerprint_mgr: CNI config dir is not set or does not exist, skipping: cni_config_dir=

I do see that there is a default being set in

nomad/client/config/config.go

Line 333 in 311886b

CNIConfigDir: "/opt/cni/config",

So I'm not sure why we aren't seeing the expected default.

I confirm that. Today I have to define cni_path & cni_config_dir in client config:

client {
  cni_path = "/opt/cni/bin"
  cni_config_dir = "/opt/cni/config"
}

Default values are overriten in agent convertClientConfig function:

nomad/command/agent/agent.go

Lines 642 to 643 in 311886b

	conf.CNIPath = agentConfig.Client.CNIPath
	conf.CNIConfigDir = agentConfig.Client.CNIConfigDir
