Hmmm...  that's an idea, I suppose.
In general, the administration side of the AgentX protocol
is very much driven by the subagent - the master agent just
listens for incoming registrations.

But the master agent *does* explicitly close any AgentX
connections when it shuts down.  I suppose that could
potentially trigger saving the configuration.

But I don't believe that the Net-SNMP agent framework
currently works that way.

Not necessarily.
If you're using the main Net-SNMP agent in a subagent role,
then that will inherit the same behaviour as the master agent,
so *would* include the usual SIGHUP handling.
  I haven't looked at the stripped-down subagent framework,
to see whether that does or not.  But it wouldn't be too
difficult to add if necessary.

And if the subagent is mostly code you've written yourself, then
it'd depend on whether you coded SIGHUP handling or not :-)

Sorry - must be a British expression.

   "There is one sure way to find out {what something tastes like,
                                       whether something works}
    That is to {suck,do} it, and see what happens."

Try it - you'll find out.
Suck it, and see.
