Haven't tried it, but it looks too simple to me. What about if in the chroot
you have say /opt/lib -> /foo/lib symlink? Basically, if you want to avoid
using chroot (a good thing), you should do pathname lookups yourself (like
use everywhere chroot_namei routine which would give you a pathname for its
argument you can then feed to system calls (when -r is not used, it would
give you the argument, otherwise it would lstat one pathname entry after
another and if encountering a symlink, it would canonicalize it, prepend
opt_chroot if it starts with a slash and make sure you don't go out of the
chroot with ../.
