How To Install driverctl on CentOS 8
Introduction
In this tutorial we learn how to install driverctl on CentOS 8.
What is driverctl
driverctl is a tool for manipulating and inspecting the system device driver choices. Devices are normally assigned to their sole designated kernel driver by default. However in some situations it may be desireable to override that default, for example to try an older driver to work around a regression in a driver or to try an experimental alternative driver. Another common use-case is pass-through drivers and driver stubs to allow userspace to drive the device, such as in case of virtualization. driverctl integrates with udev to support overriding driver selection for both cold- and hotplugged devices from the moment of discovery, but can also change already assigned drivers, assuming they are not in use by the system. The driver overrides created by driverctl are persistent across system reboots by default.
We can use yum or dnf to install driverctl on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install driverctl.
Install driverctl on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
CentOS Linux 8 - AppStream 43 kB/s | 4.3 kB 00:00
CentOS Linux 8 - BaseOS 65 kB/s | 3.9 kB 00:00
CentOS Linux 8 - ContinuousRelease 43 kB/s | 3.0 kB 00:00
CentOS Linux 8 - Extras 23 kB/s | 1.5 kB 00:00
CentOS Linux 8 - FastTrack 40 kB/s | 3.0 kB 00:00
CentOS Linux 8 - HighAvailability 36 kB/s | 3.9 kB 00:00
CentOS Linux 8 - Plus 24 kB/s | 1.5 kB 00:00
CentOS Linux 8 - PowerTools 50 kB/s | 4.3 kB 00:00
Extra Packages for Enterprise Linux Modular 8 - x86_64 13 kB/s | 9.2 kB 00:00
Extra Packages for Enterprise Linux 8 - x86_64 24 kB/s | 8.5 kB 00:00

After updating yum database, We can install driverctl using dnf by running the following command:
sudo dnf -y install driverctl
Install driverctl on CentOS 8 Using yum
Update yum database with yum using the following command.
sudo yum makecache --refresh
The output should look something like this:
CentOS Linux 8 - AppStream 43 kB/s | 4.3 kB 00:00
CentOS Linux 8 - BaseOS 65 kB/s | 3.9 kB 00:00

CentOS Linux 8 - PowerTools 50 kB/s | 4.3 kB 00:00
Extra Packages for Enterprise Linux Modular 8 - x86_64 13 kB/s | 9.2 kB 00:00
Extra Packages for Enterprise Linux 8 - x86_64 24 kB/s | 8.5 kB 00:00
Metadata cache created.
After updating yum database, We can install driverctl using yum by running the following command:
sudo yum -y install driverctl
How To Uninstall driverctl on CentOS 8
To uninstall only the driverctl package we can use the following command:
sudo dnf remove driverctl
