Would be great to collaborate!  As the SIG is still new we don't have
regular meetings set up yet, but please join #openstack-self-healing
on IRC, and you can mail the openstack-sigs list with [self-healing]
in the subject.

Yes, a spec or other docs nailing down exactly what is meant by
rolling upgrade and FFU upgrade would be a great help.  I was in the
FFU session in Dublin and it felt to me like not everyone was on the
same page yet regarding the precise definitions, making it difficult
for all projects to move forward together in a coherent fashion.
