      As Roger said, Ubuntu likes /etc/resolvconf/resolv.conf.d/. I
myself have used that in conjunction with network manager and it
worked. With that said, if you use systemd you can also configure it
that way

      And that is why ansible/chef/puppet exist. ;) With that said,
just have them use a local something for dns/ntp; it can then worry
about the ever-changing dns info from your ISP while providing the
local static and dhcp stuff.

      Now if I can do my Microsoft sucks comment of the day, it suc..
er is annoying that windows will not get ntp info from dhcp. I think
it will also cheerfully ignore dns, but I hope I am wrong...
