Viewing the networkd and resolved unit files
Before we go, I'd like you to take a quick look at the unit files for networkd and resolved. Here's the list of them:
[donnie@localhost system]$ pwd /lib/systemd/system [donnie@localhost system]$ ls -l *networkd* -rw-r--r--. 1 root root 2023 Jun 6 22:26 systemd-networkd.service -rw-r--r--. 1 root root 640 May 15 12:33 systemd-networkd.socket -rw-r--r--. 1 root root 752 Jun 6 22:26 systemd-networkd-wait-online.service [donnie@localhost system]$ ls -l *resolved* -rw-r--r--. 1 root root 1668 Aug 10 17:19 systemd-resolved.service [donnie@localhost system]$
I'm not going to take the time to trace through them for you because by now, you should be able to do that yourself. I mean, it's mainly a matter of looking everything up in the systemd.directives
man page, as we've done quite a few times before. Once you've done that, we'll wrap this baby up.
