--- Comment #1 from Lokesh Mandvekar <lsm5(a)switzerlandmail.ch> ---
Hmm, don't have a fix yet, but it seems:
Case 1: change DNS from reachable to unreachable address, DNS settings take
effect right away
Case 2: change DNS from unreachable to reachable address, the very first docker
operation fails, but subsequent ones work without a restart.
Sample run follows (on a rawhide instance):

Btw, the epel7 branch has been removed as docker is available by default on
RHEL7. Though not sure if docker 1.0.0 (and later) have made it into RHEL7
proper yet.
Changing bug Product and Version to Fedora and rawhide.
