      What were you trying to do that didn't work?

      Running the kdump nfs test from the redhat-certification test suite.  The system appears to be unable to mount the nfs device during boot and the nfs directory never mounts causing the test to fail.  kdump local works.

      Please provide the package NVR for which bug is seen:

      kexec-tools-2.0.26-8.el9.aarch64

      How reproducible:

      100%

      Steps to reproduce

      1. run the kdump nfs test from the redhat-certification test suite or just try a kdump over nfs
      2.  
      3.  

      Expected results

      The vmcore file will be written to the nfs mounted directory successfully

      Actual results

      No vmcore is written because the nfs directory is not mounted during the reboot.  We see this in the console log file
