I think the = sign is optional. Although I would prefer it in the form of
LABEL INSTALL="/usr/bin/docker run -ti --rm --privileged -v /:/host IMAGE /container/atomic-install"
And with the latest atomic we now support
LABEL INSTALL="/usr/bin/docker run -ti --rm --privileged -v /:/host \${IMAGE} /container/atomic-install"
