we fetch a given set of kernel RPMs and cache them in github cache
building locally, that's not an option, obviously...
so my thought is, if our Github workflow can mount the cache to a directory local to the akmods build, or even at a tmpdir location we can manage... we could emulate this with just, too
obviously we want fetch-kernel to be a just recipe
so, it should fetch-kernel into the local kernel-rpms/kernel-rpms/ dir
when just fetch-kerneljust fetch-kernel runs in github, that path gets cached/restored to the same path
but in local mode
running just build commonjust build common or just build zfsjust build zfs should depend on just fetch-kerneljust fetch-kernel having already run, and it could auto run if it hasn't, probably with a 5 second countdown similar to how just run-containerjust run-container will auto-build just build-containerjust build-container if needed
