      my base system has a UUID in dmidecode, but i guess the error below comes from an individual component.

      which DMI fields are being looked at to produce the below message. Thanks again

      php-cgi: rc.bootup: Creating rrd update script
      /etc/rc.d/hostid: WARNING: hostid: unable to figure out a UUID from DMI data, generating a new one
      kernel: done.

      i tried grep on the pfsense source code and get no hits for "unable to figure out a UUID from DMI data" or any shortened form...I want to find the source code generating the message, to see which DMI fields are required to be populated

        @gwaitsi to get rid of this message if you are using a cheap chinese no brand box,
        i set the following DMI values using the codes are for AMI BIOS with AMIDEDOS.EXE

        In AMIBIOS the fields are for System, Baseboard (Planar in freebsd), Chassis.

        /SM "Qotom Technology Limited" write
        /SP "Q1900G4-M" write 
        /SV "v1.1" write
        /SS "QDX08190xxxx" write
        /SK "Q190G4U-S01" write

          @gwaitsi The message is generated in the script mentioned
          /etc/rc.d/hostid

          I've used the command
          kenv -q smbios.system.uuid
          to see what kind of uuid it gets from the smbios
          My uuid was on the blacklist.
          So I changed it with the AMIDEEFIx64.EFI with option /SU AUTO

          I've found the software on this site
          https://download.schenker-tech.de/package/dmi-edit-efi-ami/

            Thanks for your leadin.
            It seems this is a defect that was fixed in opnsense but has not been fixed in pfsense.
            With your information and the
            https://forum.opnsense.org/index.php?topic=7787.0
            https://github.com/opnsense/core/commit/e49a6176
            I was able to workout, running the scripts in this order
            /etc/rc.d/hostid start
            /etc/rc.d/hostid_save start
            causes the generation of the /etc/hostid which contains the retrieved value from
            kenv -q smbios.system.uuid
            checked after reboot and the file sticks.
            Not sure what the consequences are, but i understand this is required for ZFS

              That value is unused as far as I know. It's an ugly message but it does nothing. That said it looks like a simple enough fix. Open a bug report. Or a pull request.
