From 6170c46b477d4953f91b99e805a276de444913cf Mon Sep 17 00:00:00 2001 From: Rosy Song Date: Mon, 4 Nov 2019 20:44:41 +0100 Subject: base-files: rename hostname with EUI of mac address If a label MAC address is provided for device, system will rename the hostname with OpenWrt_{eui mac address}. This helps to distinguish between different devices. Since it's no good idea to nest json_* functions, this code does not use get_mac_label directly, but only get_mac_label_dt as external resource.
