If there is a = solution to the problem I describe in the PR description in the = handbook, please be so kind and point it out to me, because I must be = blind. Also, why do the gettys get stuck and I have to kill them manually (or = reboot because they can't be killed) to reflect changes to /etc/ttys = instead of simple `kill -HUP 1`? I've never ever had to do it manually = in previous FreeBSD installations/versions. Why are they stuck in ttydtd = and not in ttyin as they are supposed to be? Thanks, mayo
