Koji content generators

[Ken Dreyer]

Hi Mike,

For the Ceph project, we're very interested in building Debian
packages on Red Hat's build system, so I've been kicking around the
idea of a Koji buildDSCFromSCM task. When I mentioned this to one of
the rel-eng guys in Red Hat, they mentioned that "content generators"
might be able to handle our use-case in Ceph. This was the first time
I'd heard of such a thing.

In your Koji 2.0 planning thread you mentioned "content generators" as
well. Can you provide more details about this?

More details coming soon, but here's the basics.

First off, content generators are not a 2.0-only feature. They will land 
in 1.x before 2.0 ships.

A content generator is a system external to Koji that performs builds 
and imports the results into Koji with robust metadata. Because it is an 
external system, it can evolve separately.

From Koji's perspective, the changes are mostly a matter of building 
that robust import mechanism. There are some schema changes involved, 
but nothing we can't manage in 1.x.

In 2.0, I see content generators becoming more central. Kojid will 
likely use the new import calls and have it's own generator id.

Stopping here for now. More to come. :)

An option may be to add Debian support to mock. Then make a tweak or option to the build commands to use a apt backend for building.
