The upper mountpoint is mostly transparent, so that the lower mountpoint is accessible. * A typical use case is mounting a tmpfs filesystem as the upper and a read-only FS as the lower mp. This way files can be edited transparently even on a RO filesystem without actually modifying it. -* The current unionfs is completely broken as it relies on the whiteout VFS technique which is not supported by HAMMER. +* The current unionfs is completely broken as it relies on the whiteout VFS technique which is not supported by HAMMER. A new unionfs implementation should not rely on archaic methods such as whiteout. Meta information: -- 2.41.0
