+Subject: [PATCH] 20-resolv.conf: improve the sitation of working with systemd
+
+systemd's resolvconf implementation ignores the protocol part.
+See https://github.com/systemd/systemd/issues/25032.
+
+When using 'dhcp server + dns server + dhcpcd + systemd', we
+get an integration issue, that is dhcpcd runs 'resolvconf -d eth0.ra',
+yet systemd's resolvconf treats it as eth0. This will delete the
+DNS information set by 'resolvconf -a eth0.dhcp'.
+
+Fortunately, 20-resolv.conf has the ability to build the resolv.conf
+file contents itself. We can just pass the generated contents to
+systemd's resolvconf. This way, the DNS information is not incorrectly
+deleted. Also, it does not cause behavior regression for dhcpcd
+in other cases.
+
+Upstream-Status: Inappropriate [OE Specific]
+This patch has been rejected by dhcpcd upstream.
+See details in https://github.com/NetworkConfiguration/dhcpcd/pull/152
