Cannot save DNS addresses

From Granular Linux Documentation

Problem

Due to an unordered list of startup services, the DNS service is not able to startup properly in some cases (not all). Due to this, the DNS (nameserver) addresses, set up by the user during the Internet connection setup, don't seem to get saved permanently, that is, the DNS addresses are erased each time the user reboots the system, and eventually the user ends up adding the DNS entries again.
