Package: ifupdown Version: 0.8.35+b1 Severity: normal Dear Maintainer,
The ifenslave package does not provides ifenslave command anymore (starting from 2.10), bonding interface needs to be done with iproute2 : # ip link set enp6s0 master bond0 I think ifupdown uses ifenslave command, because my system does not bring my bond anymore. -- Package-specific info: --- /etc/network/interfaces: # This file describes the network interfaces available on your system # and how to activate them.
