coreos-assembler: `coreos-assembler build` failing for RHCOS during `anaconda` phase

Edit: The original error below is just a symptom of an error earlier in the build phase - https://github.com/coreos/coreos-assembler/issues/325#issuecomment-461174135

Using the latest build from quay.io[1], myself and @yuqi-zhang are observing the following error when trying to build RHCOS from the internal repo:

libguestfs: error: download: /boot/loader/grub.cfg: No such file or directory

The new instructions for setting up the working directory were followed and builds were done in the context of coreos-assembler shell.
