Description of problem:

Cannot remove /var/lib/docker just after a fresh install even when docker is
stopped. And even though the docker runtime root has been changed to
/home/docker and is no longer /var/lib/docker

# rmdir /var/lib/docker
rmdir: failed to remove `/var/lib/docker': Device or resource busy

lsof does not show anyone using this file/dir

Version-Release number of selected component (if applicable):

RHEL 6
Kernel 2.6.32-431.el6
Docker version 0.11.1, build fb99f99/0.11.1

Steps to Reproduce:

1.  yum -y docker-io
2.  service docker start ; service docker stop 
3.  add -g="/home/docker" to other_args in /etc/sysconfig/docker
4.  service docker start ; service docker stop
5.  checked that the docker runtime env files are now in /home/docker
6.  Try to remove or rename /var/lib/docker and it does not allow

Actual results:
rmdir: failed to remove `/var/lib/docker': Device or resource busy

Expected results:
Should have removed or allowed to rename the directory

Since docker-1.0 is in epel, this should be fixed.
