I'm not sure where this came from originally, but it is not correct. I'll talk 
to Scott R about fixing this part of the manual.

The hob-image-*, yes. In fact any actual image files in deploy/images are OK to 
delete (excluding *zImage*, *uImage*, etc. - those are kernels). All the 
warnings are trying to prevent is people deleting the entire contents of 
deploy/images and then wondering why the kernel, bootloader etc. that get 
produced as part of the process of building an image but are not part of the 
image itself aren't re-created when they build the image again afterwards.

Cheers,
