I am trying to resolve an issue about our /etc/resolv.conf getting reset to old values or getting empty. I see a function defined in /etc/sysconfig/network-scripts/network-functions that could be causing this. This behaviour is not consistent which is making it hard to debug. At this point, I would like to know different scenarios this function is being called during the boot time. So, is there a way I can make the boot.log more 'verbose' ? Are their different logging levels for boot.log? If yes, how can I set/change it? At the moment /var/log/boot.log gives only so much details:
