I was able to get the triggers firing from devd. I a= lso noticed that the man page on 'carp' references a "carpcontrol.sh" scrip= t as an action. Has this script been prototyped anywhere yet? Mind posting the devd.conf entries you are using? Maybe submitting a docs PR with them included, to update the HAST page? Thanks. I haven't played with HAST and the new CARP code yet. --=20 Freddie Cash fjwcash@gmail.com
