In which case the -L option to limit the maximum log file size makes
sense (as does making sure that the default logging level is warnings
and above, not all sorts of informational stuff unless requested in
order to keep logs more manageable under normal circumstances).

In response to another statement made in another email, for better or
worse, OpenSM *is* a system daemon at this point.  If you don't have (or
elect not to use) a switch embedded SM, then OpenSM is necessary to keep
your fabric operational.

Or to put it another way: if you need to start it during init for your
system to operate properly, and if it needs to keep running all the
time, and if you need elevated permissions to run it, and if it has an
init script...you get the point...the rest of the world is going to tell
you this is a system daemon with console capabilities, not a console
program with daemon capabilities.  As such, always thinking of it from
the perspective of a daemon would be wise in terms of avoiding
surprising users down the road IMO.
