Yes, and the "ut" tests just via pytest do take longer. And it would be
good to have more testing in CI, and for tests to be as fast as
possible.

Looking at the run I just did on HW:

That could be better, but it's not unreasonable and part of that is
tftp'ing an 83MB kernel image.

I think if I had a point around here before, it was this. C is a
terrible language for processing strings. Python is a reasonable
language for processing strings. Neither of these statements should be
controversial. The controversy is that I'm saying tests that parse
output for results shouldn't be written in C.
