Hi! The more I read what you say the more I think that what you want is not a working stream implementation to do filesystem ops, but a way to emulate a virtual file system using stream. I don't think it is the goal of our stream implementation to do that. Tools like FuseFS are I think our str

Hi! But what about getting the metadata (as opposed to setting it)? I Most metadata widely used is covered by stat. I.e. for my itch (having functioning filesystem wrapper) it is not needed. But that doesn't mean it can't be done for other purposes :) -- Stanislav Malyshev, Software Archit
