Transaction-hook callback during bootup

I have a transaction hook of type subtree defined for a container.
the container has one leaf of type empty. when the command is executed the transaction hook is getting called correctly. But with the same command in cdb during bootup the hook is not getting called, I don’t see any errors in confd either. Am i missing something?

When you boot up with a CDB that is already populated, the transaction hook won’t be called. The transaction hook is meant to be called when you change something under the definition of the hook.

From the user guide:

tailf:transaction-hook Transaction hooks are a means to associate user code to the transaction. Whenever an element gets written, created, or deleted, user code gets invoked and can optionally write more data into the same transaction.

When your application boots up, all you can do is to either read the configuration or to trigger subscription notifications.
