From acb01526bedfb0aa96aa59cad5dec092769bd676 Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Mon, 1 Apr 2024 14:04:50 +0200 Subject: dhcpv6-client: T2590: fix vyos-hostsd update for nameserver and search domains After migrating from ISC DHCLIENT for IPv6 to wide-dhcp-client the logic which was present to update /etc/resolv.conf with the DHCP specified nameservers and also the search domain list was no longer present. This commit adds a per interface rendered script to inform vyos-hostsd about the received IPv6 nameservers and search domains.
