Not really. It adds another "locking" method to the lvm binary, that's all -
which will never be called in a single-host environment. Or it can be added as
a shared library. There's a daemon too that needs to be running if the nodes
are clustered.
One of the neat things about having it in a seperate package is that the
installation can modify the lvm config file to switch on the cluster add-ons,
rather than relying on the user doing it. Though I don't have any string
opinions one way or ther other.
