[yocto] Where do image names come from?

[Paul D. DeRocco]

Where does the base name of the image files in build/tmp/deploy/images come
from? More to the point, if I create my own image recipe in my own layer,
what control do I have over the name of the resulting image files? I'd like
to be able to create more than one variant, and not have to remember which
is which based on the build times appended to the file names.

A related question: section 5.2.1 of the dev-manual says I can create a
custom image based on an existing image by copying that image recipe and
then modifying it. Is there some reason I can't use a .bbappend for this,
e.g., core-image-base.bbappend?
