How do I specify the order that Network-Manager populates /etc/resolv.conf

Question

Network Manager is posting the correct name servers and search domains into /etc/resolv.conf when I restart the network. However, it is not in an order I like. How can I tell Network Manager to prioritize the nameservers and search domain information of a certain interface over another?

Example:

What I get:

# cat /etc/resolv.conf 
# Generated by NetworkManager
search silatria.org relinq.org pripylen.org acarime.org
nameserver 120.052.0.2
nameserver 120.052.0.1
nameserver 10.66.66.1 

What I want

# Generated by NetworkManager
search acarime.org silatria.org relinq.org pripylen.org 
nameserver 10.66.66.1  
nameserver 120.052.0.2
nameserver 120.052.0.1

acarime.org & nameserver 10.66.66.1 belongs to my network interface enp3s0 120.052.0.2.1, 120.052.0.1 & silatria.org relinq.org pripylen.org belongs to my network interface enp4s0

Solution

Set ipv4.dns-priority of at least one of the profiles, to specify the relative order.

For example

nmcli connection modify "$PROFILE" ipv4.dns-priority 5

and reactivate the connection.

See the manual nm-settings(5) for details.

It would be nice to have the version of rhel / rpm -q NetworkManager here, e.g. just in case there's a feature for it but it was added later.

Thanks, this worked!
