I just want to point out the fact that for RHEL/Fedora/etc image testing
we have the following tool:

https://github.com/RedHatQE/valid

We were using it to test Fedora images since F18.

To be honest I'm not that familiar with Taskotron but maybe we can
collaborate somehow.

In addition to that current image validation has the following:
- testing different instace types
- empty bash history
- selinux contexts test
- running services
- package set
- EBS test
- Ephemeral test
- available cores/memory test
- userdata handling (cloud-init)
- several bugs test (regressions)
- ... (full test list is here: https://github.com/RedHatQE/valid/tree/master/valid/testing_modules)
