I have tried both developers and porters handbooks
but havent found info what to do to 'commit' this
as a port, should I just submit a PR?

Thanks, at least we have 'something' we can cepend on.

I can create an 'active wait' daemon for that, like the skel below:

while sleep 3
do
  case $( sysctl -n kern.geom.conftxt ) in
    (0 DISK cd0 0 2048 hd 0 sc 0)
      echo "No CD in the drive ..."
      # umount procedure ...
      ;;
    (0 DISK cd0 * * hd 0 sc 0)
      echo "We have CD here!"
      # do something about it lile mount_cd9660
      ;;
  esac
done

But a devd(8) event would be far better, maybe some somple commit to devd(8) would help here? My knowledge does not allow me to add these bits to devd(8).
