Captures the workaround applied on k8s-node1 today (kernel rolled back
to 6.8.0-117-generic, apt-mark hold on kernel meta-packages,
/etc/os-release spoofed to 24.04 so NFD reports VERSION_ID=24.04 and
the gpu-operator picks an existing ubuntu24.04 driver image), plus the
trigger that lets us un-mitigate: any ubuntu26.04 tag appearing on
nvcr.io/nvidia/driver.
Linked from the post-mortem and from beads code-8vr0.
