You haven't done what I've done intentionally, flag /etc/resolv.conf
immutable with "chattr +i /etc/resolv.conf" have you?

I do this to keep Network Manager and other busybodies from making unwanted
/ unneeded changes.

Hi,

I had trouble with this some years ago and remember someone posting how to
stop it.

I may have. If so, is there a way to undo it?

Thanks
