Subject: [PATCH 1/6] feat(sysconfig): Add DNS from interface config to
resolv.conf (#5401)
RH-Author: Ani Sinha <anisinha@redhat.com>
RH-MergeRequest: 88: feat(sysconfig): Add DNS from interface config to resolv.conf (#5401)
RH-Jira: RHEL-17961
RH-Acked-by: Emanuele Giuseppe Esposito <eesposit@redhat.com>
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
RH-Commit: [1/1] f353b73cc0f4bb9e1aee037708a1d3cb23b83cc3 (anisinha/cloud-init)
sysconfig renderer currently only uses global dns and search domain
configuration in order to populate /etc/resolv.conf. This means it ignores
interface specific dns configuration completely. This means, when global dns
information is absent and only interface specific dns configuration is present,
/etc/resolv.conf will not have complete dns information. Fix this so that
per interface dns information is also taken into account along with global dns
configuration in order to populate /etc/resolv.conf.
Fixes: GH-5400
Signed-off-by: Ani Sinha <anisinha@redhat.com>
(cherry picked from commit 1b8030e0c7fd6fbff7e38ad1e3e6266ae50c83a5)
