Is it possible to run bind inside a nspawn container?
Created a container with pacstrap -k base into /var/lib/machines/Bind/
set root password in container
Using host networking
machinectl start Bind
machinectl login Bind
Login as root
root@Bind named]# pacman -Syy&&pacman -S bind vim
Configured bind as resolver per archlinux wiki BIND
root@Bind named]# systemctl start named&&systemctl status named

Looks like it is running in the container but can not bind to any interfaces
Looks like I am missing something or it just doesn't work.
Anyone have any magic pixie dust?
