Github user jeking3 commented on the issue:
The presence of "--domain-socket" to the client or server implies uds.
This needs to be fixed, and domain needs to be moved from haskell to nodejs,
and the cross tests that are failing (many) in the ubuntu-artful docker image
need to be investigated. For example it is likely expected for the
"http-domain" subset of tests to fail given the http-ip ones fail already,
however in one test I found that the call to fs.unlinkSync(path) [server.js]
failed because the domain socket doesn't exist before the test begins, and this
call throws an exception, causing it to fail.
