Fakeroot-ng runs a program while fooling it into
thinking it is running with root privileges. When
the program does something that only root can do
(e.g. create a device file), fakeroot-ng emulates
the appropriate system calls so that the program
gets a consistent view of its actions. Unlike the
original fakeroot, fakeroot-ng uses the ptrace
interface, which means that it does not suffer some of the limitations that fakeroot does. In particular, fakeroot-ng supports chroot jails.
