Non-VFS-based stacking solution - UnionFS, Aufs and the new Overlay FS Overayfs is essentially a rewrite of UnionMount (implemented in VFS layer), to be a filesystem. They both have several unresolved issues by design "name-based union", and I have pointed out on LKML several times. For example, here is a URL of my last post about it. http://marc.info/?l=linux-kernel&m=136310958022160&w=2 > The use case that I am looking from the stackable filesystem is that > of "diskless node handling" (for CERN where it is required to provide > a faster diskless > booting to the Large Hadron Collider Beauty nodes). Just out of curious, I remember a guy in CERN had posted a message to aufs-users ML. http://www.mail-archive.com/aufs-users@lists.sourceforge.net/msg04020.html Are you co-working with him? Or CERN totally stopped using aufs? J. R. Okajima -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
