Yeah that's a lotta hassle right there. on some systems I just drop the 
three DNS servers into /etc/resolv.conf and make sure that 
/etc/nsswitch.conf lists

```
files dns nis
```
I typically control at least two of the nameservers specified in 
resolv.conf so I can create any zone I like, but /etc/hosts being placed 
before dns in nsswitch creates a quick and dirty override for hosts. The 
problem is that you're working with MX RRs so your MTA using specific 
DNS servers w/o any AUTH zone data being reported back isn't going to 
help you with respect to mail, like it does for example, with a single A 
RR for a web site, etc.

Anyway, you got it fixed, and yes, I know I didn't cover this from a 
systemd perspective, I covered it from a Slackware perspective, which is 
typically why it's my goto and comfort zone. We're even considering 
which X to support moving forward in the wake of Wayland, presumably for 
those who aren't into that jam, and/or for those who are concerned 
(that's an understatement) that Redhat has been reverting commits, etc.

On that last point, and for those who aren't afraid of checking out and 
playing with things in "testing", it's already there and you can run 
that flavor of X if you wish to try it out (FYI, it's pretty solid 
actually). Here's a couple of resources to check out if you're interested:

https://Slackware.com
https://x11libre.net
https://github.com/x11libre/xserver

Okay... so... I lied, lolz: three sources :)

Anyway, I'm so happy that we're beyond this domain expiry stuff. That's 
not a good look, but I guess it goes without saying?

Enjoy!
