I have manually edited /etc/resolvconf/base to add openDNS name servers, and then run sudo resolvconf -u to update the /etc/resolv.conffile.

However changes are discarded on each reboot.

How do I preserve those changes?

$ cat /etc/os-release

You are placing the changes you want into the wrong directory. NetManager allows custom configuration of the file by editing the base, head and tail by placing your preferences in this directory:

/etc/resolvconf/resolv.conf.d/head

/etc/resolvconf/resolv.conf.d/base

/etc/resolvconf/resolv.conf.d/tail

You can correct this by moving your /etc/resolvconf/base to /etc/resolvconf/resolv.conf.d/base.

The content you're seeing after reboot is the content of the /etc/resolvconf/resolv.conf.d/head file. It takes precedence over all and as you can see, is preserved.

The priority choices should be placed there.
