Networking Issue: Interfaces being renamed after reboot

Did you by chance check to see if there was a bios/firmware update you could apply?

Also, if you really want to take it to the “predictable extreme” you could have your NICs named based on the mac address with something like:

storage:                                                                                                                                                                                                                                     
  files:

      contents:

          [Link]                                                                                                                                                                                                                             
          NamePolicy=mac                                                                                                                                                                                                                     
          MACAddressPolicy=persistent

Gives you a NIC names based on the mac address like enx5254009110fa.

there likely is, but these servers don’t have warranty or support and messing an upgrade for FW or BIOS could be a complete loss.
