biosdevname is Udev helper for naming devices per BIOS names

Introduction

In this tutorial we learn how to install biosdevname on CentOS 8.

What is biosdevname

biosdevname in its simplest form takes a kernel device name as an argument, and returns the BIOS-given name it “should” be. This is necessary on systems where the BIOS name for a given device (e.g. the label on the chassis is “Gb1”) doesn’t map directly and obviously to the kernel name (e.g. eth0).

We can use yum or dnf to install biosdevname on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install biosdevname.
