The checksums would change everytime the upstream code changes. As it is
right now, I might have to remove the "clone" feature because, as some
of the files get sed-edited, the changes conflict and git complains.

There were two problems: one, DECnet wants to the set lladdr of the
interface it attaches to and two, getting PyDECnet to play along as it
also needs to attach to an interface which cannot be the same as the
Linux DECnet one. Having Linux DECnet attach to a bridge solves the
first one, and hanging a macvlan off the external interface solves the
second one as you can change the macvlan's MAC all you want without
affecting the real inteface. Changing the real interface might have
caused issues with IP networking, especially ip6. IPX, DECnet, Chaos,
and ip4/6 all run on the LAN.
This is how they end up:
≻ ip -c link show br0
4: br0: mtu 1500 qdisc noqueue state UP mode
DEFAULT group default qlen 1000
link/ether aa:00:04:00:01:04 brd ff:ff:ff:ff:ff:ff
≻ ip -c link show macvlan0
16: macvlan0@eth0: mtu 1500 qdisc noqueue
state UP mode DEFAULT group default qlen 1000
link/ether aa:00:04:00:02:04 brd ff:ff:ff:ff:ff:ff
I have another RC script that sets up the bridge, although I found you
can do that in the basic Slackware scripts. Had I to do this again, I'd
have used Dnsmasq instead.

Anyone that runs (Slackware) Linux and wants to speak to DECnet nodes
might find use for it. I have a number of virtual machines; being able
to use them seemlessly is a benefit.

Of course, you can have Linux talk to another Linux if you want.
