The coreos-installer should be growing the root filesystem after installation to fill the disk and the raw image file in the simplified installer is already set to 10 GiB.

I did a local test and experienced the following error.

@yih-redhat Are you seeing anything like that in your testing?

No, I didn't see this before, but I will keep an eye on it as I am going to test the fix in osbuild/images#169
