It would be nice to use a variable name here that was not project-specific.
In Fuego, we automatically check a few different places, but we don't
check a location specified by an environment variable. However, I've wanted to
add one. I'd prefer to use the same one as other projects, if possible.
I'm shooting from the hip here, but how about something like:
Is this something that kernel-producing projects, such as Yocto Project
or Buildroot, (or Debian or Fedora, or the kernel Makefile, for that matter)
already have, or would be willing to support?
To others on the automated-testing list, does anyone else have a
variable used to specify the location of the kernel config file? If so,
what's its name?
