Omni: duplicate machine UUID problem

[smira]

Talos: use by default SMBIOS UUID, but it there's a META key with UUID override, use that value.

Omni: if the machine joins with known bad UUID, Omni established "temporary" SideroLink connection, updates META value via Talos API with random generated UUID, and the machine re-joins with new random UUID.

@smira I am facing this problem with Zimaboard and Omni. Is there a workaround/fix? I tried setting talos.config kernel parameter (https://www.talos.dev/v1.9/reference/kernel/#talosconfig) , but either I got it wrong or it is ignored.

This is not implemented in Omni (yet), but you could try to build a Talos installation media from Omni providing a META value 0xe=<other UUID> which should override the UUID provided by SMBIOS.

Sometimes hardware vendors have firmware updates fixing the issue.
