Code review comment for lp:~chipaca/snappy/pkg-types

I think saying that that will be in the _next_ MP would be ambitious. But soon.

Whether it's pkg/oem or pkg/snap/oem (with common snap-level things in snap) is unclear to me at this point, I'm keeping an open mind until I've finished worrying the code some more.

Interfaces would be in pkg, unless it got too hairy in which case I wouldn't mind pkg/interface or some such.

The fractal nature of the dependencies right now makes it hard for me to give concrete answers. You probably have more of all of this in your head, so we should discuss.
