What does that do for me?" So yeah, I would call that a fail in leadership. Us filesystem people have the highest testing requirements and ought to know how to do this best, and if the poeple with the most experience aren't trying share that knowledge and experience in the form of collaborating on tooling, what the fuck are we even doing here?

This stuff doesn't have to be huge multi engineer-year projects to get anything useful done. ktest has been a tiny side project for me. If I can turn that into a full blown CI that runs arbitrary self contained VM tests with quick turnaround and a nice git log UI, in my spare time, why can't we pitch in together instead of each running in different directions and collaborate and communicate a bit better instead of bitching so much?
