I'm not sure what OpenSuse does. But, openresolv does sort entries by
ifname. You can put /etc/resolvconf.conf to modify the default
policy. My /etc/resolvconf.conf is as follows for example:
resolv_conf=/etc/resolv.conf
resolv_conf_options=edns0
# If you run a local name server, you should uncomment the below line and
# configure your subscribers configuration files below.
#name_servers=127.0.0.1
#dynamic_order="tap[0-9]* tun[0-9]* ng[0-9]*:* ng[0-9]* vpn vpn[0-9]* ppp[0-9]* ippp[0-9]*"
interface_order="lo lo[0-9]* [a-z]*[0-9]*:*"
In my environment, dhclient adds the entry as em0, rtsold adds the
entry as em0:slaac, and dhcp6c adds the entry as em0:dhcpv6. So,
above conf prefer IPv6 over IPv4.
The problem is that openresolv distinguish the entries just by an
fname. We need to distinguish them by the source or by the address
family, too. The proposal from hrs-san addresses this issue.
Sincerely,
