also something I found in the output of `cat /var/log/syslog | grep -i tun`:
`KERN: loaded driver /boot/system/non-packaged/add-ons/kernel/drivers/dev/net/tun`
`KERN: devfs: reload driver "tun" (4, 10227)`
`KERN: devfs: "tun" api_version missing`
`KERN: devfs: "tun" madatory driver symbol(s) missing!`
