[ENOTSUP] The file identified by fd cannot be associated with
the ACL because the file system on which the file is
located does not support this.
[EPERM] The process does not have appropriate privilege to
perform the operation to set the ACL.
[EROFS] This function requires modification of a file system
which is currently read-only.
