Hey thanks for the response.  I was sending the information but this is
the first email that seems to have hit the list.  Such goes the way of

# may specify:
#
#   "destroy",        meaning that the domain is cleaned up as normal;
#   "restart",        meaning that a new domain is started in place of
the old

domain is

#   "rename-restart", meaning that the old domain is not cleaned up,
but is
#                     renamed and a new domain started in its place.
