Hi all!

The use case I think about is as follows: 

A configuration node  in a YANG model is effective only after a system-restart 
(i.e. not only a restart of the NETCONF server). Now I would like to see from a 
YANG model if a system-restart actually has to be carried out for that node. 
E.g. as system operator I would like to know from the model only if I have to 
wait and poll for the operational state resulting from the configuration, or if 
I have to actively restart the system. At the end, I would like to publish a 
YANG model such that the model's user is able to derive his or her actions only 
from that model without further studying any documentation.

Modelling how to perform a system-restart is easy, as I have seen in the draft 
"Factory default Setting". Recognising its necessity is the difficulty here.

What would be the best practice here?

I can think about three options:

1) Explicitly modelling the property "system-restart needed", e.g. by a leaf 
next to the configuration node.

2) Providing a YANG module listing all configuration nodes requiring a 
system-restart.

3) Using the startup datastore. However, as the conventional configuration 
datastores have all the same datastore schema, there seems to be no  
possibility to see the property "system-start needed". Otherwise, it could have 
been modelled by a configuration node in the startup datastore, and as status 
node in all other datastores.

I highly appreciate any hints. - Thanks.

Regards,
Wolfgang
