        Release Notes: This minor feature enhancement release handles symlinks for /bin, /lib, and /sbin if they point into /usr (as Fedora 17 does) and uses -pthreads instead of -lpthreads, if available, so it will compile on some modern Linux versions.

            Software with a similar purpose: Plash

            You might also be interested in Plash, which also creates
            restricted environments for running programs in. Like
            jailkit, you can specify what files a process can access, but
            you don't need to copy the files, so it's more lightweight
            and flexible. You can grant a process read-only or
            read-write access to specific directories, mapped at any
            point in the file namespace.
