For now I figured I'd just wing it. I want to at least every 2 weeks look over
master commits for suitable backports, and then just judge from there. Not
sure it's worth the effort to cut regular releases if no compelling bug fixes
are accumulating.

I figured for now I could just scrape the commits manually. If I'm missing
things or being overly patch happy maybe we can figure out some process, but
at this point it seems overkill.

But if there's a bug fix that people think it's worth accelerating a stable
release for, just CC me and comment to that effect.

Yeah one of my main goals at the start is making the process as simple as
possible and have near zero impact on current libvirt git and release
processes. Agreed that seeing how it turns out might necessitate more process
but we'll just have to see.
