Hi Folks,
not sure if this is a bug or a feature but had been scratching my head for months now running BIND on Fedora22-24 and all the time I did a reboot BIND didn’t came up and I needed to restart the process to get it running. After some googling around I realized that I am not alone with this but there has never been a clear solution beside some proposals to change the sequence of IPv4/IPv6 entries within ifcfg which didn’t work for me.
Finally I found a dependency but I am still not sure where the root course is related to, as it depends on if empty-zones-enable is set to yes/no?
named -v
