Hi Andrew,
Thanks for the details.
The Puppet config should never have let it be setup with
allow_mult=false, but as this is a test cluster, it's possible
something went awry there at some point.
If it's not really a bug that needs reporting then I can let it go.
Thanks,,
Toby

Turning and turning in the widening gyre
The falcon cannot hear the falconer
Things fall apart; the center cannot hold
Mere anarchy is loosed upon the world
