systemd defines a default set of fallback DNS servers in https://github.com/systemd/systemd/blob/v251/meson_options.txt#L328-L330
By adding a PACKAGECONFIG knob providing a convenient way to opt out, and then adding that value to systemd's PACKAGECONFIG, the output from runtime 'resolvectl status' command no longer contains the following line: Fallback DNS Servers: 1.1.1.1#cloudflare-dns.com 8.8.8.8#dns.google 1.0.0.1#cloudflare-dns.com 8.8.4.4#dns.google 2606:4700:4700::1111#cloudflare-dns.com 2001:4860:4860::8888#dns.google 2606:4700:4700::1001#cloudflare-dns.com 2001:4860:4860::8844#dns.google Signed-off-by: Niko Mauno <niko.ma...@vaisala.com> --- meta/recipes-core/systemd/systemd_251.4.bb | 1 + 1 file changed, 1 insertion(+) diff --git a/meta/recipes-core/systemd/systemd_251.4.bb b/meta/recipes-core/systemd/systemd_251.4.bb index 8497e24af9..910ea71bf6 100644 --- a/meta/recipes-core/systemd/systemd_251.4.bb +++ b/meta/recipes-core/systemd/systemd_251.4.bb @@ -163,6 +163,7 @@ PACKAGECONFIG[manpages] = "-Dman=true,-Dman=false,libxslt-native xmlto-native do PACKAGECONFIG[microhttpd] = "-Dmicrohttpd=true,-Dmicrohttpd=false,libmicrohttpd" PACKAGECONFIG[myhostname] = "-Dnss-myhostname=true,-Dnss-myhostname=false,,libnss-myhostname" PACKAGECONFIG[networkd] = "-Dnetworkd=true,-Dnetworkd=false" +PACKAGECONFIG[no-dns-fallback] = "-Ddns-servers=" PACKAGECONFIG[nss] = "-Dnss-systemd=true,-Dnss-systemd=false" PACKAGECONFIG[nss-mymachines] = "-Dnss-mymachines=true,-Dnss-mymachines=false" PACKAGECONFIG[nss-resolve] = "-Dnss-resolve=true,-Dnss-resolve=false" -- 2.35.1
