I think this is in login - unless I mis-parsed your statement.

If enough login attempts to brute-force (by top-100, or dictionary even)
your root password aren't giving you enough logging feedback to
recognize that the attempt is being made, that's a different problem.

I'd like to see a better method for NetBSD systems to alert the sysadmin
to critical events, like RAID disk failures, or breakin attempts, in
realtime. Syslog alone is insufficient - but this is a different thread
;-)

Please add them to the PR. I was looking at it a few months back, and
started pulling the changes forward - but if you already have them,
they're more likely to go in soon(er) :-)
