Hi,

We started relying on docker for the cache. Are you using docker or
podman? There should be a RUNC variable in config-host.mak that you can
check.

And for the record, which version of either podman or docker?


Alex, 

I think we might need to add DOCKER_BUILDKIT=1 $(RUNC) ... to properly
make use of caching with docker. As for podman, I'm seeing conflicting
information on the web as to whether it even supports caching.
