Hey Carter,

I agree that perhaps this is too exotic for a new command line parameter.

However, have you ever considered configuring the daemons and clients
by reading state progressively from a variety of contexts using a
well-defined naming convention. Perhaps as follows, allowing
subsequent contexts to override values set in the former:

compiled in defaults
rarc
environment varliables (e.g. export $ARGUS_GENERATE_MAC_DATA=yes)
existing short command line parmaters (e.g. -m)
new long command line parameters (e.g. -o ARGUS_GENERATE_MAC_DATA=yes)

This would provide a very flexible and consistent framework for
configuration. In my case, wherever possible I run my clients with the
-X option (ignore rarc) and pass the configuration via command line
parameters. (This is my personal preference and since all of this is
meta to the core Argus functionality I can well understand if you
disagree or consider it not worth the effort!).

That's great - thanks!
