Ah, sorry, I overlooked this. For the volume mount _O_CREAT is no
required, of course. It is expected, that the volume already exists.

The PNUT filesystem doesn't require explicit mounting, all will be done
when registering the device. Mounting is required only for multivolume
or changeable devices.

Something like

 fh = _open("PNUT:testfile.txt", _O_CREAT | _O_TRUNC);

should work immediately, without mounting the volume first.

Please try and check the example in nut/app/ftpd.
