freebsd-wifibox: Config directories don't mount inside VM

Hello,

I’m trying to configure wifibox as AP. I added passthru device and started wifibox: service wireguard start

wifibox console:

localhost:~# ifconfig 
localhost:~# 

localhost:~# mount
/dev/root on / type squashfs (ro,relatime,errors=continue)
devtmpfs on /dev type devtmpfs (rw,nosuid,noexec,relatime,size=10240k,nr_inodes=13653,mode=755)

localhost:~# cat /etc/fstab 
tmpfs      /tmp       tmpfs    size=128K                                     0 0

app_config /etc/hostapd 9p trans=virtio,rw 0 0

localhost:~# mount app_config
mount: permission denied (are you root?)
localhost:~# id

As you see, VM doesn’t mount config directories. And as a result, doesn’t bringing up network interfaces.

Don’t have any idea where should I dig to solve this problem. Could you please advise me?

Also please add sample configuration about creating AP. man 8 wifibox has nice samples but nothing regarding hostapd config or setup AP in general. It would be great to have hostapd/hostapd.conf with commented sample configuration. Users could just uncomment sample config and edit it according to their needs instead of reading man hostapd.

Thank you!
