Our Linux Kernel is 3.10 running on an embedded mips processor with busybox. The init script has -
echo "/sbin/mdev" > /proc/sys/kernel/hotplug mdev -s
We have a rule to rename a network interface of USB to Ethernet adapter on seeing a ADD action. On hotplugging the adapter, I see that the interface does get renamed but the same does not happen on reboot.
