Description Karl Hastings 2014-07-11 14:18:17 UTC 
Description of problem:
docker's systemd unit file should have allow users to pass options to the docker daemon through a "$DOCKER_OPTS=" line in /etc/sysconfig/docker

Version-Release number of selected component (if applicable):
docker-0.11.1-19.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Try to pass options to the docker daemon via '/etc/sysconfig/docker'
2. 
3.

Actual results:
Not able to

Expected results:
setting a variable like 'DOCKER_OPTS="-D=true -g=/mnt/docker" ' in /etc/sysconfig/docker should pass those items to docker on daemon startup.
