I was amazed when my OpenBSD network config worked on the first try using only the man pages as reference.

On the other hand it took me the better part of an hour to figure out how to change the DNS server used by an Ubuntu install.

Might I ask why/how exactly?

Well, I first checked /etc/resolv.conf which told me to change the dns settings in systemd. So I read up on the systemd documentation and tried to change the dns setting using systemd-resolved but got a permissions error. So I did a bunch of reading online and found out that netplan is actually used to configure the dns so I spent some time reading the netplan documentation on how to change the dns server. This process took me about an hour.
