Well, you can call the cluster-glue ones directly too; at least the
"external" scripts, which by now seem to be all of those that really
matter ;-)

Yes, that tends to suck. My life would be much better if better
insulated against reality!
(And a previous obsession with run-time-loadable C plugins with silly
interfaces. Turns out C really sucks for interfacing with text-based
interfaces, surprise. And then they needed memory *anyway* for their
network calls and external programs ...)

Sad, I was hoping it'd help simplify interfaces somewhere.
But there's still the gain of not maintaining certain modules twice,
getting access to those that are in the other, and a reduced admin/user
story. So I hope it's going to be worth it anyway.

Yeah, another thing I like about fence-agents as shown there is how they
are broken out into sub-packages, so one doesn't pull in all those
dependencies in one go.
