I'd like to highlight and echo Chris' (Hofstaedtler) comment:

| As I wrote earlier, I believe this is non-ideal. Each image builder
| will have to learn it, and each image builder will do something
| different. You'll end up with various configurations in the wild
| that you don't know that they exist.

*Please* let's avoid a solution for which every single image
builder tool needs to special case things.

(Speaking with my hat as author of grml-debootstrap (which exists
since 2006) and project lead of the Grml rescue live system, and
being a previous contributor and maintainer of initramfs-tools.
Please don't think about autopkgtest + vmdb2 only, there are *many*
image builder tools around.)
