        udevadm: merge all udev tools into a single binary
    
    The oldest supported distributions have these much newer versions of
    udev:
      Distro             EOL        udevadm -V
      Debian 8           2020-Apr   215 (combined systemd and udev)
      RHEL / CentOS 7    2024-Jun   219 (combined systemd and udev)
      Ubuntu 16.04 LTS   2021-Apr   229 (combined systemd and udev)
