I run into the same problem today and tried to figure out
what could be a way also to included fixed interfaces configured
in /etc/network/interfaces.d.

So, I slightly changed at the end of 00-network (from configure_network on)
== snip ==
configure_network()
{
    gen_network_configuration > /etc/network/interfaces
    echo "source /etc/network/interfaces.d/*.cfg" >> /etc/network/interfaces
}

deactivate_network()
{
    . /etc/os-release
    if [ $ID = "ubuntu" ]; then
        IFACES=`/sbin/ifquery -la`

        for i in $IFACES; do
            DEV=`get_dev $i`
            /sbin/ifdown $i
        done
    else
        service networking stop
    fi
}

activate_network()
{
    . /etc/os-release
    if [ $ID = "ubuntu" ]; then
        IFACES=`/sbin/ifquery -la`

        for i in $IFACES; do
            DEV=`get_dev $i`
            /sbin/ifup $i
        done
    else
        service networking stop
        sleep 1
        service networking start
    fi

    sleep 2
}

deactivate_network
configure_network
activate_network
== snip ==

That works fine for me - especially in a mixed setup where I want to
use the context on the one hand, but have the need to configure alias
interfaces on the other hand (which is only handy on a VM with a 
fixed configuration).

What I did not check yet if that influences somehow any other kind of
package (relying on existing interfaces)

Best, Michael

Also a "service networking restart" does not work. The only workaround I found for now is to reboot the VM, then networking works correctly.
