Hi Ken,

Did you consider cutting a new patch-level release with these fixes?
That would help determining the presence of the fixes for bug reports
and questions.  Which is even more important if you don't plan to make
further 1.x releases.

I guess this applies all the same for clusters defined without a
Corosync nodelist.  Right?
