红帽全球峰会1.3. The Linux kernel RPM package overview
The kernel RPM is a meta package that does not contain any files, but rather ensures that the following required sub-packages are properly installed:
kernel-core-
Provides the binary image of the Linux kernel (
vmlinuz). kernel-modules-core- Provides the basic kernel modules to ensure core functionality. This includes the modules essential for the proper functioning of the most commonly used hardware.
kernel-modules-
Provides the remaining kernel modules that are not present in
kernel-modules-core.
The kernel-core and kernel-modules-core sub-packages together can be used in virtualized and cloud environments to provide a RHEL 10 kernel with a quick boot time and a small disk size footprint. kernel-modules sub-package is usually unnecessary for such deployments.
Optional kernel packages are for example:
kernel-modules-extra- Provides kernel modules for uncommonly used kernel modules. Loading of the modules in this package is disabled by default.
kernel-debug- Provides a kernel with many debugging options enabled for kernel diagnosis, at the expense of reduced performance.
kernel-tools- Provides tools for manipulating the Linux kernel and supporting documentation.
kernel-devel-
Provides the kernel headers and makefiles that are enough to build modules against the
kernelpackage. kernel-abi-stablelists-
Provides information pertaining to the RHEL kernel ABI, including a list of kernel symbols required by external Linux kernel modules and a
dnfplug-in to aid enforcement. kernel-headers- Includes the C header files that specify the interface between the Linux kernel and user-space libraries and programs. The header files define structures and constants required for building most standard programs.
kernel-uki-virtContains the Unified Kernel Image (UKI) of the RHEL kernel.
UKI combines the Linux kernel,
initramfs(initial RAM file system), and the kernel command line into a single signed binary which can be booted directly from the UEFI firmware.kernel-uki-virtcontains the required kernel modules to run in virtualized and cloud environments and can be used instead of thekernel-coresub-package.
