 I couldn't reproduce with the testcase in the above paste; with
 oneiric's apt (0.8.14.1ubuntu5):
>>> import apt
>>> apt.Cache(rootdir='apt-test')
creating:  apt-test/var/lib/dpkg
creating:  apt-test/var/cache/apt/archives/partial
creating:  apt-test/var/lib/apt/lists/partial
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/apt/cache.py", line 93, in __init__
    self.open(progress)
  File "/usr/lib/python2.7/dist-packages/apt/cache.py", line 136, in open
    self._cache = apt_pkg.Cache(progress)
SystemError: E:Could not open file apt-test/var/lib/apt/apt-test/var/lib/dpkg/status - open (2: No such file or directory), E:The package lists or status file could not be parsed or opened.
>>> c=apt.Cache(rootdir='/home/lool/h/apt-test')
>>> c.update()
True

 I do have at least one PPA in my sources.list.  I suppose APT is still
 reading some data from / instead of rootdir (perhaps via apt-key).

 I also couldn't reproduce with
 "linaro-hwpack-create hwpacks/linaro-panda 12" as run from a checkout
 of
 lp:~linaro-maintainers/linaro-images/hwpack.natty.linaro-panda

 Probably the same problem
