Description Kevin Pouget 2021-09-27 09:13:36 UTC 
RHCOS version is not exposed by the Node Feature Discovery labels.

This value, available through the host /etc/os-release `OSTREE_VERSION`, would allow scheduling OS (and kernel) specific Pods on all the nodes running with the same OS version.

This is necessary for proper upgrade support of kernel-specific workloads, such as Pods handling kernel drivers.
