Also a lame excuse for doing 4627| | it here. 4628| | 3) Less important technically, but the net-snmp agent 4629| | doesn't currently handle registrations of different 4630| | engineIDs either and it would have been a lot more work 4631| | to implement there since we'd need to support that 4632| | first. :-/ Supporting multiple context engineIDs should 4633| | be done anyway, so it's not a valid excuse here. 4634| | 4) There is a lot less to do if we trump the agent at this 4635| | point;
