Comment 11 for bug 566793

I verified the initial test case (with user data while loop on)
$ dpkg-query --show eucalyptus*
eucalyptus-cc 1.6.2-0ubuntu30.1
eucalyptus-cloud 1.6.2-0ubuntu30.1
eucalyptus-common 1.6.2-0ubuntu30.1
eucalyptus-gl 1.6.2-0ubuntu30.1
eucalyptus-java-common 1.6.2-0ubuntu30.1
eucalyptus-javadeps
eucalyptus-sc 1.6.2-0ubuntu30.1
eucalyptus-walrus 1.6.2-0ubuntu30.1

After several minutes of waiting i went back to get console output. I saw:
=====
hello, number 4997
hello, number 4998
hello, number 4999
run-parts: /var/lib/cloud/data/scripts/part-000 exited with return code 1
Traceback (most recent call last):

    raise Exception(str)

(interestingly, that is correct output. the python trace results from the script being run and returning non-true).
