People would like to be able to override or append these variables from the AB interface. This is in flight now, but marking it for tracking purposes.
http://git.yoctoproject.org/cgit/cgit.cgi/yocto-autobuilder/log/?h=eflanagan/kernel-override Currently reviewing if this meets the basic needs right now. May need another iteration through for corner cases/additional requirements.
Marking as resolved.
