  Compare the following two.

  1.16.3 (Ubuntu/Jammy) output:

  # nvme list

  2.8.2 (Ubuntu/Noble) output:

  The difference is this: 1.92  TB vs 15.36  TB, and 960.20  GB vs 7.68  TB.

  The drives did not suddenly get bigger, but the problem is described here:
  https://github.com/linux-nvme/nvme-cli/issues/2260
  And fixed here:
  https://github.com/linux-nvme/libnvme/pull/803/commits/00efe8364b0a

  This fix is included in:
  https://github.com/linux-nvme/libnvme/releases/tag/v1.9

  That is not available in the 2.8 version:

    # nvme --version
    nvme version 2.8 (git 2.8)
    libnvme version 1.8 (git 1.8)

  But it should be in the Oracular 2.10 one:

    nvme-cli (2.10-1) sid; urgency=medium
    [...]
      * Bumping libnvme build-depends to 1.10.

  Suggested patch fixes things, as can be seen here:

    # nvme list -o json | grep -vE 'ModelNumber|SerialNumber' >old
    (switch to 0osso0 patched build)
    # nvme list -o json | grep -vE 'ModelNumber|SerialNumber' >new

    # apt-cache policy libnvme1t64
