then there is wayback, which is kinda a bridge between any filesystem, and the version controlled, so lets say you have /mnt/bigstorage, with a mofo raid mounted, then you do this: mkdir /mnt/cvsfs fusemount wayback_thing /mnt/bigstorage /mnt/cvsfs.. ^^ not how you do, but you get the idea. http://wayback.sourceforge.net/ > >It is one of my university projects to make this kind of filesystem or > >modify some existing filesystem eg ReiserFS. > > > > > Please send a design document. > > >Any sugestions how to implement or where to start?
