# Listening on individual IPv6 interfaces does not work

This is usually due to "/proc/net/if_inet6" not being available in the chroot file system. Mount another instance of "proc" in the chroot file system. 

This can be be made permanent by adding a second instance to /etc/fstab.


```
proc /proc           proc defaults 0 0
proc /var/named/proc proc defaults 0 0
```
