NFS errno values

The following system call errno values are the result of various NFS call failures:

EINTR
A system call was interrupted when the intr option was used on a hard-mounted filesystem.

EACCES
A user attempted to access a file without proper credentials. This error is usually caused by mapping root or anonymous users to nobody, a user that has almost no permissions on files in the exported filesystem.

EBUSY
The superuser attempted to unmount a filesystem that was in use on the NFS client.

ENOSPC
The fileserver has run out of room on the disk to which the client is attempting an NFS write operation.

ESTALE
An NFS client has asked the server to reference a file that has either been freed or reused by another client.

EREMOTE
An attempt was made to NFS-mount a filesystem that is itself NFS-mounted on the server. Multihop NFS-mounts are not allowed. This error is reported by mount on the NFS client.
