[OE-core] Changes to Image Definitions in 1.7.1

[Walter Giroir]

Hello Gary,

Thanks for the response.  

The problem is that the IMAGE_CMD for the IMAGE_FSTYPE cannot be found in image.py. 
The details are below.


What I have discovered is that the layer’s classes directory is…
  1. No longer required
  2. No longer parsed.

In 1.5.1 if I remove the layer’s classes directory, I received a “Missing classes” error.
In 1.7.1, not even a warning is generated.

Putting this class in the classes directory goes without error or warning
 dd if=/dev/urandom count=10 of=a.bbclass

The IMAGE_CLASSES is defined in the machine configuration



And here is the error

Details?  Otherwise, you'll only get guesses :-(
