Comment 2 for bug 1839480

I've provided coaching to describe the problem and how to fix it.

The code fixes are to be done in live-build, rather than in casper, given that layered images incorrectly generate layers without executing the right hooks at the right layer...

Didier and jibel had complete description of what is happening with interactive debugging in a hangout.

@WillCooke @PatGaughen => can you please schedule live-build work to fix layers generation?
