The default value is described in the manual. And how about this one? +The special I/O requests from aufs include a part of copy-up, lookup, +directory handling, pseudo-link and xino file operations. +For example, Unix filesystems allow you to rmdir(2) which has no write +permission bit, if its parent directory has write permission bit. In aufs, the +removing direcoty may or may not have whiteout or 'dir opaque' mark as its +child. And aufs needs to unlink(2) them before rmdir(2). +Therefore aufs delegates the actual unlink(2) and rmdir(2) to another kernel +thread which has been created already and has a superuser privilege.
