No problem, now netplan, but i cant tell you much about netplan out of experiance, i've never used it.
But what is it exact you want to know??
The how and why i configure like this is already a bit explained.
about this part:
> So, I'm curious about the contrast between modifying netplan vs simply disabling systemd.resolved
But I did a bit reading. (https://netplan.io/) and that looks ok, so the contrast here imo, there isnt.
once you configured with netplan, networkmanager and systemd-networkd/resolved use the netplan config.
So, now its a new one on my todo list to figure a setup with netplan. Thanks guys ;-/
Now a nice example of why to configure network/dns and stay in scope of the systems viewpoint.
I was also a victum of such upgrade problems multiple times yes. to configure outside the systems viewpoint. ( long ago ubuntu 8.x/10.x Debian 4-5-6 )
Understanding "my way" of installing.. I'll try to keep it a short message.. and remember its "my way" not a preffered way, its my preffered way of installing.
I install minimal, as minimal as possible at least for servers.
Ubuntu does not like my way of installing thats also why i higly preffer Debian.
( Things like /vmlinux not found, grub problems due to usb install, i installed to little, and due to that unable to boot of other program errors. )
then i setup the needed tools i want to use. just things like an editor and basic tools.
- i start with the basic network settings, ip and resolving and i make sure this is 100% correct.
what i use, well, i dont care about this, i use thats offered in the minimal install so in ubuntu 14.04 it was primary networkmanager now its systemd-networkd.
Just take some time to read into a new thing and do that when the server is still at a minimal install, and most important, use minimal changes.
If you change a default system file, ALWAYS backup it before changing it.
- (if used optional) configure DNS server.
- setup a time server, or configure it to get a good time source ( any domain member points always to the primary NTP in the LAN )
These to are the most important things to configure. a good network setup and time server setup.
After these i test my resolving. And as of this point i setup based on the use of the server.
I install in the same order, always, because the keeps e steps easy to repeat and if something goes wrong its more easy to track down.
This is why i created this.
This order is also how i always install my servers and anyone can adopt this for any os.
Just follow the install order, try it and see if you encounter problems. I'll bet you get problem but less then before.
So in my opinion, its not about whats prefered or how its configured, it about what/how you install and use it, then you can think about howto configure it and whats preffered.
Did i make sence here?

Sorry to bother you more, Louis...
Can you take a quick whack at this?

I'd honestly prefer disabling systemd.resolved - but would like to understand your way of doing it better, so I can make an informed choice.
Thanks [and sorry all for the thread drifting from strictly Samba stuff...]
LPHvBvs> And yes, i can confirm that Rowland is correct about my point of view.
LPHvBvs> I'll also explain a bit why so people can understand my thoughts.
LPHvBvs> I install a server as minimal as possible, yes, you might
LPHvBvs> miss some packages, but you can install these after the base setup.
LPHvBvs> The Why is, This saves a lot of space, unneeded
LPHvBvs> updates/upgrade of packages you dont use and it results in a more stable server.
LPHvBvs> I setup with, at least i try to, as less as possible of
LPHvBvs> adjustment of the default config files and try to stay in
LPHvBvs> line with the thoughts of the developers.
LPHvBvs> The Why is, and you upgrade packages or the OS upgrade,
LPHvBvs> lesser problems and lesser you need to upgrade to quicker and
LPHvBvs> more save for unattended upgrade.
LPHvBvs> Because if this all my servers run with unattended upgrades.
LPHvBvs> Daily all packages, kernel reboot needed, in the weekends.
LPHvBvs> This is why i dont care about sysv services systemd
LPHvBvs> whatever, use it how to os is designed.
LPHvBvs> And if you dont like it, .. ( sorry for the example ) like
LPHvBvs> Rowland and systemd, he switched to Devuan.
LPHvBvs> A Debian version but without systemd.
LPHvBvs> I dont like Ubuntu, but i do like Debian.
LPHvBvs> You think, but its the same, no, totaly not, yes, same
LPHvBvs> packages, but not the same in how the system runs.
LPHvBvs> A good example is how the resolving is done, the "unneeded"
LPHvBvs> packages ubuntu installs which only slows down your system.
LPHvBvs> My vision.
LPHvBvs> Servers, Debian stable, no gui as minimal as possible.
LPHvBvs> * A note, companies might need, ubuntu or RedHat due to
LPHvBvs> hardware/software support and regulations.
LPHvBvs> Desktop, Debian stable/Ubuntu Desktop/Ubuntu Mate/Mint
LPHvBvs> Regular user, keep the desktop defaults.
LPHvBvs> user like me, install the minimal desktop.
LPHvBvs> Media server, kodi/plex etc, Ubuntu server.
LPHvBvs> Debian is getting better here, but i have not tested that.
