I support this draft as a starting place for this work, but I would like to see some changes in the final solution:

I think that having a datastore report the factory default configuration is good, and it is also right that this should be optional to implement, since some devices might not have default factory configuration, but instead run a first boot sequence to construct an initial configuration.

I don’t really understand the need to be able to perform a factory reset on a per datastore basis, but instead I would prefer to see a single device level factory reset RPC.  Such an RPC may do more than just resetting the configuration and rebooting the device, it might also change the software version, wipe areas of storage such as log files, cached files, etc.  Possibly, some of these options could be controlled via parameters to the RPC if there is enough commonality, of otherwise vendors could augment in their own options to a minimal standard RPC.

Copying from <factory-default> to another datastore is OK with me, although I don’t see any particular need/value in doing this, hence I would rather see <copy-config> fixed more generically to allow copying between two configuration datastores than specifically augmenting specifically for this datastore.  Hence, I think that extending/replacing the <copy-config> RPC could probably be deferred to a NETCONF-bis or NETCONF-NMDA-bis document.

I don’t see a need for this document to reference or refer to the instances-data draft.  I think that using instance-data rather than a factory-default datastore is just an internal implementation detail and shouldn’t be exposed to the user.

However, Balazs, I do see merit in allowing the contents of any configuration datastore to be loaded from an instance-data file, or written to an instance data file (either local or remote).   But, I don’t think that this should go into this draft, and probably it is too late to add this to the instance-data draft.

Thanks,
Rob
