MCREATE has no effect in Linux. On Plan 9, it means something different than what you are trying to use it for. Read Plan 9's bind(1) and bind(2) if you are interested. > 2.

The createfile function in the lib9p library manipulates File trees and doesn't have anything to do with 9P proper, but the "cannot clone open fid" is a 9P error; Russ
