thanks for the feedbacks.  Were .pyc files used instead of the .py
version in oVirt?  IIUIC, pyc files maintain the same information as the
original source file, while .pyo files are a optimized version that has
not all the original content.  Using the optimized version, I could
strip 55 MB of space from the Fedora Atomic image, if I use .pyc then
the reduction is only 27 MB.

Nick, would .pyc be a safe alternative to .py files or are there still
cases where it doesn't work in the same way?

Thanks,
Giuseppe
