v2.2.0

Added

• Enhanced debugging via environment variable: NFS_LOG_LEVEL=DEBUG. This also produces less cluttered log output during regular, non-debug operation.

Fixed

• idmapd would not start when NFS_VERSION=3
• allow Kerberos without idmapd. Most users will probably want to run them together, but it isn't required.
• NFS_VERSION environment variable sanity check allowed invalid values
• status code of rpc.svcgssd was not properly checked
• idmapd debug output was invisible
