I set my nameservers all manually in this file and they do
not every change. I do not run systemd. I'm not sure
of your issue(s) but, historically, resolv.conf should not
be displaying this behavior.

I do not try and force the "eth' names onto an interface
I have these in rc-status:

mtab | boot                          
net.enp5s0 |      default
netmount |      default

I just look at the dmesg output and use the new, default
funky names. You can read up on these evolving interface
names by googling.
