Don't be hard on yourself. I don't think this task is easy.
Unfortunately for you (and me) I have the horrible ability to look at
koji build stuff and know pretty closely whether it looks sane or not.
This isn't your help, I just need to go and do something else :-P

At times as a programmer it's hard to see the forrest for the trees.
We'll get there.

Interesting, that's currently probably about right with the current
set of builders. When we go to just yosemite/rainer builders I think
this will close out quite a bit which is why I'd be interested to see
in particular the guru/smarttop devices removed (and even the
cdot-panda* due to the nfs loopback because they're slow compared to
the hsv-panda* with the local usb disk).

Looking good. It's interesting as it brings up some statistical
wierdness even on mainline [1] so it just goes to show it's not just
arm that has random builds :-)

Good work!
