I'm building a docker image in a build, and about 7 out of every 10 builds hangs while trying to interact with the docker daemon.

Here is my image buiding task:

  - build-image: |
      cd voidshrieker
      sudo nohup dockerd &
      sleep 10
      sudo docker build -t void/nginx .
      sudo docker save void/nginx:latest > webimage.tar
      sudo chmod 644 webimage.tar

and here is the output I get in the log:

+ cd voidshrieker
+ sleep 10
+ sudo nohup dockerd
nohup: appending output to 'nohup.out'

and after that nothing more.

I added a comment about this to #298 and ~sircmpwn asked me to open a new ticket and shout out to ~eschwarz due to this happening on an archlinux build image.

My build is using the archlinux image, I should have mentioned that, sorry.

Adding a +1 to this - my build hangs right after staring docker - here's the hanging task:

  - build-image: |
      cd voidshrieker
      sudo nohup dockerd &
      sleep 10
      sudo docker build -t void/nginx .
      sudo docker save void/nginx:latest > webimage.tar
      sudo chmod 644 webimage.tar

I see the following logs:

+ cd voidshrieker
+ sleep 10
+ sudo nohup dockerd
nohup: appending output to 'nohup.out'

and then nothing else. Similarly, sometimes it works fine when I cancel and resubmit, but not always.

It would be super helpful if you could ssh into a canceled build as you can a failed build, otherwise you have to wait a very long time to investigate.
