Hi Dean,

If I understood your query correctly, I can't seem to replicate your 
issue, and I need some steps so that I fully understand.

My configuration file is set as:

  dpdk_build:
    dpdk_tree: /home/luca/dpdk
    remote: true
    precompiled_build_dir: build

and running:

   ./main.py --config-file my-conf.yaml

works just as expected. It re-uses my pre-build DPDK repository on my 
SUT node. We tried every setup:

   (tree, tarball)*(local, remote)*(precompiled, build_options)

and we were able to get it to work without issue. In case I 
misunderstood your problem I just attempted to call:

   (cd ../ && git archive --format=tar.gz -o dts/dpdk-HEAD.tar.gz \
     --prefix dpdk-HEAD/ HEAD)
   ./main.py --config-file my-conf.yaml --tarball dpdk.tar.gz

and as expected it failed because my configuration was assuming a 
precompiled build dir in my tarball, but it copied and extracted the 
tarball on the remote correctly. Changing from precompiled to build, 
made it fully work.

Looking forward to hearing back from you.

Best,
Luca
