Outdated documentation MAC address pine64

[PanderMusubi]

The text in the line https://github.com/armbian/documentation/blame/master/docs/board_details/pine64.md#L6 is outdated. The file /boot/uEnv.txt is no longer used. Setting ethaddr in there, using all the information from https://docs.armbian.com/User-Guide_Basic-Troubleshooting/#mac-address-conflicts or runninng nmtui does not result in setting a MAC address.

Is the MAC address randomly set each time? If not, where is it stored? I cannot find the MAC address anywhere, however, rebooting results always in the same MAC address. Perhaps the random process is random for the board but is persistent in providing the same address?

The link to the script setting the random MAC address should be https://github.com/armbian/build/blob/main/packages/bsp/common/usr/lib/armbian/armbian-firstrun
However, it is still unclear to me where that address is stored for subsequent reboots.
