Comment 2 for bug 1700912

I wouldn't worry about SIGHUPs -- we should just make it so that the package is present on the node before starting any containers. That's doable both for fresh deployment and upgrade.

As for the package though, that might be more difficult. Tripleo-common is currently on undercloud only, we'd probably have to start installing it on overcloud too, which might be ok but would have to be double checked, as i think we had some issues with installing e.g. python-tripleoclient on overcloud, IIRC.
