[Gluster-devel] [Gluster-users] User-serviceable snapshots design

I asked if we were dynamically changing the client graph to add new
protocol/client instances.  Here is Varun's answer.

Apparently the addition he mentions wasn't the kind I was asking about,
but something that only occurs at normal volfile-generation time.  Is
that correct?

So we still have dynamically added graphs, but they're wrapped up in
GFAPI objects?  Let's be sure to capture that nuance in v2 of the spec.
