In v2, in the config directory, there can be other directories named
<server/cluster>-config. For example, if you have a cluster named
"c1", there could be a "config/c1-config" directory. On Byron's
sample cluster machine, there's a bunch of these directories. They
each seem to have "docroot" and "lib" subdirectories.
Can someone explain when these are created? Does (e.g.) create-cluster
create the corresponding config directory? Does it populate it with
default docroot and lib directories?
When these directories are synchronized to the corresponding instances,
do they end up with the same names?
Or, does (e.g.) config/c1-config/docroot end up as just "docroot" on
all the instances of c1?
