Looks like this flew under my radar, but just thought I'd mention that
it breaks the Linux-HA CTDB resource agent, which makes heavy use of
ctdbd command line parameters:
https://github.com/ClusterLabs/resource-agents/blob/master/heartbeat/CTDB#L624

I guess it should be possible to have the resource agent generate a
runtime ctdb configuration file, but it'll likely cause quite some
headaches WRT multi-version support.
