Hi Martin,

The option all_squash does not affect files or directories.
It replaces RPC request credentials sent by nfs client with
user nobody:nobody. The newly created files will be owned by
nobody:nobody, if parent directory permission
(and export rules) allow to do so.

Best regards,
   Tigran.
