AndersW had floated a patch for this -
http://list.opensaf.org/pipermail/devel/2013-January/028573.html .
However this topic needs a little more consideration. This ticket/patch by
itself isnot having any problems, however it opens up a lot of other things
that were not possible without this patch like performing admin op on
middleware SU.
One of them is, for AMF to allow the below commands only if they are initiated
by SMF, i.e. during upgrade. For instance AMF could achieve this by seeing if a
campaign is in progress(sumaintenance campaign attribute?)
amf-adm lock safSu=SC-2\,safSg=2N\,safApp=OpenSAF
amf-adm lock-in safSu=SC-2\,safSg=2N\,safApp=OpenSAF
amf-adm unlock-in safSu=SC-2\,safSg=2N\,safApp=OpenSAF
Also, additional considerations discussed in the below links have to be
accounted for:

Migrating this ticket for reference:
With the exception of immnd, the services started by NID cannot be restarted by
AMF. This is because they always assume that they were started by NID, and
therefore do not register with AMF.
The logic in immnd for handling start from either NID or AMF should be reused
also in the other NID started services.

Actually, the IMMD is also monitored by the AMF, but that monitorign can only
start
after the AMF is up, which has to be after IMMNDs have loaded.
The problem should only exist for early starting services.

And "early starting services" I suppose equals NID started services.

Except IMMND, other services are not restartable services. Once any one of
those services are down, node reboots.

milestone changed from 4.2.2 to future_releases
I removed the milestone for this ticket since we haven't concluded what this is
about yet. As Nags say, an active NID started service cannot just be restarted
if it crash. But there are other problems. NID does not supervise its started
services more than one by one. It forget each one after it has responded. This
is not good since when AMF starts any NID started service could be down and it
is not really designed for that.
Another use case is that unlock-instantiation of the 2N opensaf SU does not
work because of this. This use case could be useful to change the actual AMF
model of opensaf itself.
