[csw-users] NFS shared /opt anyone?

We do not use a configuration management system for opencsw delivered packages. We don't use everything available from opencsw, only about 50 or so applications that are key to us and I don't think they are of a highly configurable nature.

We are in the purely NFS-share /opt camp.

Here's one example.  Suppose that you deliver configuration files to
/etc/opt/csw so that they are zone-local on sparse zones with shared
/opt/csw.  If you do that, they configuration files are not available
on the shared NFS solution, because they aren't under the shared
/opt/csw directory.  If you choose to deliver configuration files to
/opt/csw/etc, they are available, if not modifiable, in the shared NFS
solution.  The downside is that you cannot modify then on sparse
non-global zones.

My position on the topic is that if you're using the shared NFS
solution, you can use a configuration management system such as puppet
or cfengine to deploy your configuration files to /etc/opt/csw.  I
would assume that any larger Solaris installation requires such a
solution, but I heard that there is a deployment that does not use any
configuration management system, and it requires configuration files
under /opt/csw/etc.

There are also issues with alternatives, and generally class action scripts.

How are NFS-based deployments managing the configuration files, do you
guys use a configuration management system, or is it purely NFS-shared
