From my point of view, this may be confusing for a user, as it could lead to think that something is wrong. But I think that, even if image post processing during the build is preferable, there are some image post processing that just cannot be done there. Think for example of any HW identifier, like a MAC address that you might want to use.

I agree, I'll change it to a note. The excessive use of bb.warn 
pre-dates my patchset though. I'll resend the patchset tomorrow.

First, let's get it to master. I had a bit of trouble convincing the 
community that this needs to be done last time (about one year ago), so 
I appreciate the support :)
