--- Comment #5 from Devan Goodwin dgoodwin@redhat.com --- I've been going back through old docker-io versions trying to see if this appeared recently, it seems to appear in everything I tested.
I can do this operation fine on a RHEL 7 host, also docker 1.0.0.
This leads me to believe it's (a) not something in Fedora 20 container itself, and (b) some other Fedora component beside docker-io.
