To have the ethernet devices called enp3s0 and enp5s0 (on my machine), rather than eth0 and eth1, is annoying.
Appending biosdevname=0 net.ifnames=0 to the kernel command line improves quality of life.

Some solutions I feel are out of proportion to the problem they supposedly solve; often they introduce new ones.
Imagine a help page, telling a beginner to dhcpcd <insert_your_device_name> rather than simply dhcpcd eth0
