Thanks for replying. There is only one reference to configadmin in the
cellar docs:
http://karaf.apache.org/manual/cellar/latest/user-guide/index.html
How would I modify the etc/config.properties to be able to sync
etc/a/b/c/foo.properties?
Also, it would be nice if the Cellar docs was in one
Where is the documentation on how the ConfigAdmin works???

A quick google gave me this result [1], and the first entry is for
configuration admin service [2].
As the Fileinstaller does take care of parsing the cfg files and therefore
transfering those to the config admin service, find the documentation for
the FileInstaller at [3]

Don't let's forget http://www.osgi.org/Download/HomePage where you can
download the original service specifications, which are both very clear
about how the service has to behave and completely abstract concerning the
means employed. And as Achim points out, there are a lot of tutorials etc.

Populate from an external repository
If you have a bunch of artifacts to upload, it’s not very efficient to use
the cave:upload-artifact command.
The cave:populate-repository command allows you to upload a set of artifacts

No, it's not what I meant.
Cellar just broadcast the instructions to do.
So, feature:repo-add on one node will be done on the other node.
To do that, the nodes have to share a repository (Cave is not necessary).
So, all nodes have to share the same Maven repository (as defined in

Hi,
You will need Cave 3.0.0 (that will be in vote during the week end).
But Cave is one solution, any Maven repository works (a basic one could
be a Maven directory structure on a shared filesystem, or a Maven
directory structure exposed using Apache httpd).

Hi,
the Win VM and Mac Host are supposed to be in the same cluster ?
If so, the network multicast doesn't work and so Cellar can't discover
the nodes.
To fix that, you can switch to static IP addresses definition.
On each node, you modify etc/hazelcast.xml, and you add the IP addresses

If by install, you mean drop into the deploy folder or install from the
