OpenShift 4.19 os-release ID="rhel" instead of ID="rhcos" install-blobfuse-proxy crash

[jsanchezmartinez]

What happened:
After upgrading to OpenShift 4.19, the CSI node init container crashes due to is not using "install-proxy-rhcos.sh" (instead using install-prox.sh") because the ID of os-release is now rhel instead of rhcos.
Any advice?
