Yes.

RFS uses internally a canonical form to pass arguments back and forth between
the server and the client machines. The caller converts its arguments into this
canonical form and the callee converts this canonical form back into structures
or whatever types are needed, making it independent of any byte-ordering or
alignment requirements.
