  * user-chroot: A setuid program that allows non-root users to safely chroot(2)
  *
+ * "safely": I believe that this program, when deployed as setuid on a
+ * typical "distribution" such as RHEL or Debian, does not, even when
+ * used in combination with typical software installed on that
+ * distribution, allow privilege escalation.
