By default root on a client is mapped to user nobody on an NFS server. If a user or group ID is 0, Amazon EFS treats that user as the root user, and bypasses permissions checks (allowing access and modification to all file system objects). Root-squashing allows an NFS server to map any incoming user ID 0 or guest ID 0 to another number that does not have super user privileges, often -2 (the nobody user).

The Game took on the gameplay of NFS: Most Wanted and NFS Carbon, focusing on illegal street racing, tuning cars and police chases, and added MMO elements to the mix. If your applications require the root users on NFS clients to access Secure NFS filesystems with root privileges then a unique root user credential needs to be created for every NFS client system that will be configured in a filesystems’ “root=” access list. Root: The Tabletop Roleplaying Game is a game of woodland creatures fighting for money, justice, and freedom from powers far greater than them. All requests of a non-root user on are attempted as the same user on the server (user mapping). This might result in a failure of such features as vMotion.
