>Description:
devd(8) writes its pid into /var/run/devd.pid, but the pid there is 1
lower than the actual pid of devd. This is because devd is started by
default without the -n switch, so it writes the pidfile before calling
daemon(8).
>How-To-Repeat:
# devd
# cat /var/run/devd.pid
720
# ps auxww | grep devd
root 721 0,0 0,2 772 532 ?? Is 10:22pm 0:00,00 devd
>Fix:
Simply write the pidfile again after calling daemon(3).
