Does it work properly when single node?

[thegenius]

I carefully read the document of Garage, there is a large amount of words describe the cluster feature and layout.
But in many small project, single node is enough.
So the question bother me now is this:
Does garage work properly in single node environment?
when I modify the garage.toml with:

replication_factor = 1

I got this warning:
WARN garage_rpc::layout::version: Ring not yet ready, read/writes will be lost!
