Caused by too much security checks at the wrong place ('mock-helper
chroot ...' gives full control over the system, so these path-checks
(which can be workarounded with symlinks) are senseless). Best thing for
functionality would be:

* execute mock in an own namespace; so you do not have to care about
  unmounting
* do the mounting nativly (call 'mount(2)' instead of exec(2) the 'mount'
  command)
* for all other commands, do just an 'execv(argv[1], argv+1)' in
  mock-helpers main() routine

Patches for the first two points are existing already.
