A few questions: Could this be done as a stackable file system (vnode layer distributed file system) or did you have something else in mind (i.e. specifically a full implementation of a network filesystem including storage layer)? Why not a port of an existing network filesystem say from Linux? (A BSD rewrite could be done, if the code was GPLed.) Would cross-platform capabilities make sense? How do you see this comparing to device-level solutions? I know the argument can be made to implement file systems/storage abstractions at multiple layers, but I thought I might ask. The other thing is there a wealth of filesystem papers out there, any in specific caught your eye? > Eric > > > > -- > ------------------------------------------------------------------------ > Eric Anderson Sr. Systems Administrator Centaur Technology > A lost ounce of gold may be found, a lost moment of time never. > ------------------------------------------------------------------------ -- Allan Fields
