Stefan Hajnoczi - June 7, 2013, 11:58 a.m.
From: Kevin Wolf <kwolf@redhat.com>

The original intention seems to be something with handling multiple
images at once, but this has never been implemented and the only
function ever registered is implemented to make everything behave like a
"global" command. Just do that unconditionally now.
