And that would be a non-Qt job. I wasn't worried about Qt on real devices 
because I don't expect it to be run early enough to matter.  On VMs, that's 
another story, and if you don't trust your undercloud-provided /dev/hwrng, why 
are you using that cloud? (Though I'll say there's an Intel team working on 
figuring out how a VM can get trust from the actual hardware, skipping the 
hypervisor trust)

Anyway, I've read the entire Python thread to figure out what their conclusion 
was. Turns out, after spending hours reading everything, the bug ends without 
a conclusion. It must have been concluded, but it's not recorded in the bug 
report!
