Early on in the Branched release, it is typically using a pre-release version of the kernel, so each Release Candidate (RC) is built for Branched releases. Once the kernel is released, it receives stable updates just like the stable Fedora releases. From time to time, the Fedora kernel maintainers get asked to build something into the. Kernel-abi-whitelists — Contains information pertaining to the Fedora kernel ABI. (Optional) If your initramfs-kernelversion file does not match the version of the latest kernel in /boot, or, in certain other situations, you might need to generate an initramfs file with the Dracut utility. Fedora Labs is a selection of curated bundles of purpose-driven software and content as curated and maintained by members of the Fedora Community. These may be installed as standalone full versions of Fedora or as add-ons to existing Fedora installations. It can be useful to know the version number of the kernel (i.e., the core of the operating system) on a particular Linux system. Not only is it instructive in itself, but it can also be helpful in diagnosing and upgrading systems because each release of the kernel contains some differences, sometimes minor and sometimes substantial.
In this article and related video, we will be discussing how to check the kernel version in both Ubuntu and CentOS Linux. The following command works with all Linux distributions, such as Red Hat, CentOS, Debian, and Ubuntu. It also works on other UNIX-like operating systems such as HPUX, FreeBSD, OpenBSD, Solaris, etc. Use the following command to check which kernel version your server is currently running:
Here’s the code to run from the command line:
Phone forensics software. uname -r
You should receive a result similar to the following:
2.6.32-431.11.2.el6.x86_64
How to find Linux kernel version. I am using Ubuntu 16.04 while writing this article. But these commands are generic and can be used on Fedora, Debian, CentOS, SUSE Linux or any other Linux distribution. Fedpkg co -a kernel Contributing to the Fedora kernel. If you are sending patches for the first time, there is a guide to help you. For one-off fixes, send them to the Fedora kernel mailing list, or if they are relevant upstream, send them directly to linux-kernel@vger.kernel.org and Fedora will inherit them on the next rebase.
| The kernel version output from above can be interpreted with the following key: | ||
| 2.6.32-431.11.2.el6.x86_64 | ||
| 2 | = | The Main Kernel Version |
| 6 | = | The Major Revision |
| 32 | = | The Minor Revision |
| 431.11.2.el6 | = | The Minor Fix/Revision Detail |
