OK so I just bought a shiny new test machine, and installed one of the
big name distros on it, hoping they've moved ahead and bought into the kunit
story...

$ grep KUNIT /boot/config-6.8.0-52-generic
# CONFIG_KUNIT is not set

...gagghh! No such luck. One more data point, in support of Yuri's complaint. :)

Yes they should! kunit really does have important advantages for many use
cases, including bitmaps here, and "CONFIG_KUNIT is not set" is the main
obstacle.

Let me add a few people to Cc who might be able to influence some distros.
