results->blackout_recovery_time,
I looked at the code and gave up before even trying to understand it. the
function call or macro was covering 43 lines. That is it's not a function that
is implemented in 43 lines it's the actual call that is 43 lines of code.

Closing, as this is pretty old, and only Ubuntu LTS is supported (e.g. 16.04,
18.04).
