We're having issues with a customer having RedHat 7 PC's shutdown intermittently.
One was just sent in for repair, and I'd like to check the journald output.
However, I've read the rebooting the system overwrites it.
How can I view this journal without rebooting the system? Do I need a bootable RedHat or Centos USB stick? If so, how to I create it? How would I then view the drive/file?
