Previously, the code prefixes the chroot path to actual file paths to simulate the effect. This, however, will not work for tzset(3) which expects the current system have a working set of timezone data files, and that is not always the case. This changeset simplifies the handling of paths and use an actual chroot(2) call to implement the effect.
