+
+deprecated alternative: run `make` to use the makefile however that uses docker instead of podman and only builds x86_64
+
+`make.sh` is necessarily(?) overengineered because:
+* podman keeps burning dockerhub pulls by not using the cached images (`--pull=never` does not apply to manifests)
+* podman cannot build from a local manifest, only local images or remote manifests
+
+but I don't really know what i'm doing here 💩
+
+* auth for pushing images to repos;

+  `podman login ghcr.io -u 9001`
