- Using public DNS servers leads to user's domain queries being known to the
servers, violating privacy. However, it is necessary to address many corner
cases when DNS servers are not known to systemd-resolved but internet
connectivity is working. Allow users to disable fallback DNS servers.
Tests:
- After upgrade to latest version of FreedomBox, the setting is on by default.
- Disabling removes the /etc configuration file and resolvectl shows no fallback
DNS entries.
- Enabling add the /etc configuration file and resolvectl shows fallback
entries. After removing existing DNS servers using resolvectl, one can still
query using fallback servers.
