 * Digest of manual page of chroot system call - No.61
 *
 * chroot - change root directory
 *
 * Synopsis
 *     #include <unistd.h>
 *
 *     int chroot(const char *path);
 *
 * Description
 *     chroot changes the root directory to that specified in
 *     path. This dirctory will be used for path names beginning
 *     with /. The root directory is inherited by all children
 *     of the current process.
 *
 *     Only the super-user may change the root directory.
 *
 *     Note that this call does not change the current working
 *     directory, so that '.' can be outside the tree rooted at
 *     '/'. In particular, the super-user can escape from a
 *     'chroot jail' by doing 'mkdir foo; chroot foo; cd ..'.
