translucency loadable kernel module

translucency is a loadable kernel module for Linux that virtually merges two directories, making it possible to overwrite files on read-only media and compile projects (such as the Linux kernel) with different options without copying sources each time. No user-space tools have to be changed. The process is also known as inheriting (ifs), stacking, translucency (tfs), loopback (lofs), and overlay (ovlfs).
