Hello! When I was building dragora, I unmounted the wrong device. So build process was interrupted. To continue building I ran command (from BOOTSTRAPPING.md) for building all packages again. Qi started ignoring already builded packages but I got an error when qi reached kernel-buildtree-generic package. When qi ignored kernel-generic package, the package couldn't define variables with names: kernel_generic_version and kernel_generic_release so when qi started processing kernel-buildtree-generic package, it couldn't define version and release variables in recipe of kernel-buildtree-generic.
P.S I also want to propose to rename kernel-buildtree-generic to kernel-buildtree
