No, it's obviously very clearly NOT better with '-D' in ipmon_flags!
This is not the first time someone has "lost" the '-D' when configuring
It's a _REQUIRED_ option for this usage of the program -- it should be
given explicitly in the rc script just as other scripts give all
required options to the daemons they invoke without leaving their
specification up to the administrator who may not even know the full
requirements of the environment created by /etc/rc.

What's the point of doing temporary monitoring of filter actions?
Yes you might want to ignore them most times, but surely you'd simply
drop the "log" keyword from the rules if that were the case, no?
I'm sure Darren can confirm his original idea of how "ipmon" would be
invoked and used.... I know I've suggested the SysV idea before and
he's not denied it, but neither did he reply to the messages in which I
made the suggestion.

'-D' was added to ipmon somewhere between 3.2.3 and 3.2.4, and thus
first in NetBSD-1.4 (and in NetBSD-1.3.3) -- confusion surrounding its
use has been long standing.
