now then...there you go getting all excited again.  please, let's keep
this civil.  :P

okay, but it's better now, with the -D in the defaults.

actually, i'd have to ask around, but it strikes me that ipmon was
*not* written in the "sysv style" but as a tool that admins were
expected to use from the command line that *later* had the "daemon"
functionality added to it.

the user is expected to be happy with the flags as provided, since we
think we're a smart bunch and know how things are supposed to work.
the user is also, imho, expected to find out what the flags do if they
are considering changing them.  that's what i do.

actually, this all seems to stem from a problem with some old
documentation somewhere...
