      Context thread.

      Description of problem:

           Monitoring the 4.18 agent-based installer CI job for s390x (https://github.com/openshift/release/pull/50293) I discovered unexpected behavoir onces the installation triggers reboot into disk step for the 2nd and 3rd control plane nodes. (The first control plane node is rebooted last because it's also the bootstrap node). Instead of rebooting successully as expected, it fails to find the OSTree and drops to dracut, stalling the installation.

      Version-Release number of selected component (if applicable):

          OpenShift 4.18 on s390x only; discovered using agent installer

      How reproducible:

          Try to install OpenShift 4.18 using agent-based installer on s390x

      Steps to Reproduce:

          1. Boot nodes with XML (see attached)
    2. Wait for installation to get to reboot phase.

      Actual results:

          Control plane nodes fail to reboot.

      Expected results:

          Control plane nodes reboot and installation progresses.

      Additional info:

          See attached logs.
