Debian used to assign network devices based on MAC address.
If you want to continue doing something like that, use the
kernel boot parameter

   net.ifnames=0

and create your own udev rule.  For example:

   /etc/udev/rules.d/76-netnames.rules:

   # Create custom network interface names based on MAC address.
   SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:11:25:86:61:87", NAME="net0"

This rule will assign the Ethernet adapter with MAC address 00:11:25:86:61:87
the interface name net0.  Reference the interface by this name in
/etc/network/interfaces.

I hope this helps.
