Great, I'll try and find time to commit it next week.

Thanks!

I'm not sure why, I suspect hysterical raisins. I've also thought this
odd and agree we should use the machine db. I think the best approach
would be to add generic to XB-Subarchitecture and handle it using the
db, leaving the other subarches as the are.

Right.
