this is a set of logs collected by
https://gist.github.com/smoser/e0cd7fafef8f52c24571
I'm posting them here to show that this seems pretty functional and reliable at the moment. It installed trusty-hwe-u, trusty-hwe-v, vivid, wily in a loop 15 times each. It did fail on runs 16-20, but I believe the ipmi serial died, and since check for success was based on that, it marked them as failed and I did not get logs.

I'm not sure what exactly those block devices are (as in if they're
raided in hardware or they actually represent physical spinning disks).
But I do know that writing data to sda causes that data to be readable
from sdg.
The same is true:
sda -> sdg
sdb -> sdh
That is what causes those UUIDs to be similar. Everything is
functional, you just have to know that if your root device is /dev/sdg
that you should probably not write data to /dev/sda thinking you can use
it as a disk.
