AFAIK, the guarantee provided by all Unix systems is that non-root users can't escape from chroot. I can't find a good reference, but that's always been my understanding of this system call. root's limitations in chroot vary by operating system.

It's safe to trust chroot as long as you drop root before executing untrusted code.
