I agree this is an issue. However, usually the PID is generated from the
startup script so that only the PID which is started by it is stopped.
Specifically, think of the use case of starting multiple SM's on different
ports. For example a local user may do this to manage 2 subnets from one
node. Your patch will, by default, overwrite the PID file with each instance.
(yes --pid-file can be specified but this is not very standard.)
I think a better (and more standard) approach is to do the following (untested):
diff --git a/scripts/opensm.init.in b/scripts/opensm.init.in
