I think a bunch of the problems you are having are with the build of
the `swarmd` binary. That's not something I would expect Debian users
to want to use (it's more of a development aid) and hence something
which I think doesn't need to be packaged. The real purpose for
packaging swarmkit is to satisfy the dependencies of the moby/Docker
engine build i.e. to provide the library parts.

If you disable the build of the output binaries in swarmkit and treat
it as a pure "library" package I reckon a lot of your troubles will go
away.

The current set of binaries appear to be "swarmd swarmctl swarm-bench
swarm-rafttool protoc-gen-gogoswarm". I think you should drop "swarmd
swarmctl" and I think "swarm-bench" too.

I pressume you'll have to keep protoc-gen-gogoswarm for the build to
work, but that shouldn't have any problematic depenencies.

That leaves "swarm-rafttool" which I'm not sure about, it looks like it
would be useful for debugging Docker in swarm mode issues in the field.
I'd say if it doesn't cause problems keep it, but at the first sign of
complexity dump it.
