I am using RCN debian 8.0 jessie on a beaglebone black.
I am using a usb to wifi adaptor, and my ethernet port is unused.
Yet my syslog is full with these messages:

Why is dhclient running when eth0 is off? shouldn’t this be up only in case eth0 is up?
I intend to close this and use systemd dhclient, this way:
First create this file: nano -w /etc/systemd/network/LAN.network:
[Match]
Name=eth0[Network]
DHCP=v4
Second enable and start the service:
