It operates according to three rules:\n  1) The first directory is read-only and the second one is writeable. New files\n     are created under the writeable directory, but read from both directories.\n  2) If a file exists under both directories, the one under the read-only\n     directory is preferred. This improves security, as files (e.g /bin/login)\n     cannot be overwritten using external access to the writeable directory.\n  3) Non-root processes cannot open new file descriptors via luufs (e.g open\n     files), but can use existing file descriptors.\n\nTherefore, luufs can be used to secure servers: they can be trapped under a\nluufs mount point (using chroot), with a writeable directory mounted with the\nMS_NOEXEC and MS_NODEV flags.\n\nIn addition, luufs has a read-only mirroring mode, in which a directory is\nmirrored and changes are disallowed. It is similar to a bind mount, but may be\nread-only even if the specified directory is writable.\n\nLegal Information\n=================\n\nluufs is licensed under the MIT license, see COPYING for the license\ntext.
