That is absolutely true, and does not discount at all my implication
that "copying my own file over the top of /etc/resolv.conf after
dhclient runs and hoping there's no other race conditions that catch
me out", is perhaps a little "abnormal" in terms of a networking

Or the user is not achieving their outcome due to not using the

:D - my condolences for your achievement in "using" some feature of

Indeed, there are many ways to sking this cat - network manager,
chattr, cp -o "with-crossed fingers" my-resolv.conf /etc/resolv.conf,
manual commands added in /e/n/i, /etc/resolvconf/resolv.conf.d/ -
even the Windows IT guys from the other department of the OP might be
able to update their DHCPd settings to deliver the desired DNS
server, when the MAC addresses get configured - do 2 things at the
Really, it would be easy to argue there are too many ways to skin
Good luck all,
