How can I permanetly add the following 'echo "2" > /sys/devices/cpu/rdpmc' to RHCOS ?

I would like to be able to permanently add the following echo value echo "2" > /sys/devices/cpu/rdpmcto RHCOS through a machine-config in OCPv4.12.X on-wards

Hi, I know this is a bit confusing but this forum is for ostree, which is low level OS agnostic tooling to update operating systems. It's independent of OCP for example.

Now, directly writing to /sys via Ignition will likely break with MachineConfig; what you'll need to do instead is write a systemd unit that does e.g. ExecStart=/bin/sh -c 'echo 2 > /sys/devices/cpu/rdpmc' for example.
