Hi all,
sorry for the cross post but I need help and I'm not sure = where it hangs.

I create linux jail (debian bullseye) via cbsd.
the jail is being populated with the debian = userland..
so far so good... services running = (sshd) and I can login to the jail, I also can update packages and = I can install apache httpd and all works fine (apt install or make from = src).
I also manage to install packages even if = their scripts depend on "ip" command that fails:
cbsd@j2> ip
Cannot open netlink socket: = Address family not supported by protocol

ifconfig show empty = interfaces:
cbsd@j2> ifconfig
eth0: = flags=3D4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        ether 00:50:56:0a:b3:a0 =  (Ethernet)
        RX packets = 139798314  bytes 12029597009 (11.2 GiB)
    =     RX errors 0  dropped 0  overruns 0  frame = 0
        TX packets 26879143 =  bytes 34400160833 (32.0 GiB)
      =   TX errors 0  dropped 0 overruns 0  carrier 0 =  collisions 0

lo0: = flags=3D4169<UP,LOOPBACK,RUNNING,MULTICAST>  mtu 16384
        loop  (Local Loopback)
        RX packets 28548  bytes = 160312960 (152.8 MiB)
        RX = errors 0  dropped 0  overruns 0  frame 0
        TX packets 28548  bytes = 160312960 (152.8 MiB)
        TX = errors 0  dropped 0 overruns 0  carrier 0  collisions = 0

I know linux emulation doesn't implement netlink.. so what I = do is fake the response by replacing /bin/ip by a bash script that = prints the correct IP and fakes some other (needed by packages i = Installed):
#!/bin/bash
if [ "$1" =3D "-o" ]; then
echo "1: eth0 inet = 192.168.1.2/24 brd 192.168.1.255 scope global eth0"
elif [ "$1" =3D "route" ]; then
    =     if [ "$2" =3D "get" ]; then
    =             echo "8.8.8.8 via  192.168.1.2   dev eth0  src  192.168.1.2  "
        else
                echo = "default via  192.168.1.2   dev eth0"
    =     fi
else
echo "1: eth0: = <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen = 1000"
echo "  inet  192.168.1.2  /24 brd  192.168.1.255 scope global eth0"


still ifconfig shows no IP... its time to say it a regular = jail and *NOT* VNET.

*however* package that pull ips via libraries = fail..
eg: installed bind916 (name) in the logs I = see these errors (relevant only):
cbsd@j2> = service named start
Starting domain name service...: = namednamed: prctl(PR_SET_DUMPABLE) failed: Invalid argument
cbsd@j2>
