ÂIn lieu of stackable file system approaches, I was hoping to see those VFS-based approaches get the support needed to get merged, and yet they have not. ÂIt appears that development of the VFS-based approaches has stalled, sadly. ÂTo be fair, I have argued before that adding a lot of code to the VFS "just" to support unioning was a bad idea (see http://lkml.org/lkml/2007/12/13/242). ÂAnd I also felt that it was going to be hard to support approaches which required changes (however small) to many individual file systems (e.g., to add native whiteout support). But was I'd have been happy to see a VFS-based approach get merged, if the Powers That Be[â] sanctioned it. Is there any reason why unionmount could not use the xattrs which are natively supported by most filesystem already like overlayfs does? That would cut on the sheer number of patches required to get it working.
