      #. MUST online a swap partition with a well known PARTLABEL: OCPSWAP - PARTLABEL (/dev/disk/by-partlabel/)
      #. MUST online a swap file with a well known path /var/tmp/ocpswap.file
      #. MUST be backwards compatible with the file paths wasp used in the docs in 4.21
      #. MUST set default swap priorities DISK/PART higher than FILE - in order to have faster NVME rioritized over whatever file
      #. Does not have to be configurable at this stage

      PR has been posted, seems to be on track for FF.

      This will be DP or TP. Thus behind a FG in HCO.
      If FG is open, then the MCs should be rolled out on every cluster.

      Goal

      Move the onlineing of swap from wasp (which is manually deployed) into MachineConfigs which are always deployed automatically by HCO. Transparent to the user.
