FreeBSD-base repository and kernel configuration

[Grzegorz Junka]

Is it possible/feasible to also include the kernel configuration name 
when creating the repository with "make packages"?

I am thinking about a scenario where I have multiple kernel 
configuration (e.g. for testing) and would like to install kernel/world 
from a specific configuration.

Something like /usr/obj/usr/src/repo/FreeBSD:12:amd64:generic/ or 
/usr/obj/usr/src/repo/FreeBSD:12:amd64/generic/

That's assuming that the world might differ when a different kernel 
configuration is used, not sure if that's true, I think it's true with 
regards to some package, e.g. drm-fbsd12.0-kmod.
