I'm using Armbian 21.08.2 Focal with Linux 5.10.60-sunxi and I try to setup a bonding interface for failover between eth and wifi.
It doesn't seem to work after a reboot.
Where are all the interface's files? In RHEL it's under /etc/sysconfig/network, debian it's supposed to be /etc/network/interfaces but this last one contains only
source /etc/network/interfaces.d/*
# Network is managed by Network manager
auto lo
iface lo inet loopback
Thanks!
