+++ This bug was initially created as a clone of Bug #749722 +++
Description of problem:
The update notice says:
  Hopefully doing this doesn't break existing usage of --chroot and
  --shell but if it does please report it as a BZ so we can fix it.

There you go, the update breaks my existing usage of --shell. :)

**

I often debug failed builds in a mock chroot. However, I can no more go into the chroot, since su asks for the chroot root password:

<mock-chroot>[mockbuild@flxray1 /]$ su - mockbuild
Password: 

$ rpm -q mock
mock-1.1.16-1.fc15.noarch
