Machines booting with inconsistent UUIDs

[majst01]

According to: https://smartdatacenter.topicbox.com/groups/sdc-discuss/T6163493dd08e0603-M3ade214b147fa7d3419e944d/server-uuids we are not the only facing this issue. But the system uuid can be set with sum according to: https://www.supermicro.com/support/faqs/faq.cfm?faq=33551

This means we should probably set the machine uuid to a new random one on the very first boot from the metal-hammer

I remember that we already saw some painful things happening when setting the UUID through sum. Then, sometimes Redfish reports a different UUID than the ipmitool and we did not find a way how to resolve this (persisted even after BMC reboot).

In a discussion we decided that there is not much to do about because this behavior comes from the vendor and there is no good workaround to choose from.

Also we want to document this behavior in the metal-stack docs and write up a small paragraph about how to resolve this.
