Kernel Package Compatibility

Unlike the ABI upward compatibility policy on Windows, on Linux, certain versions of Linux kernel packages are generally not compatible with higher kernel versions. Because new features and improvements are added as kernel versions go up, installing an older version of a kernel package can cause compatibility issues. Of course, in some cases, kernel packages are compatible with higher kernel versions. For example, if a kernel package for kernel version 5.15.0 works with kernel version 5.16.0, this is because kernel version 5.16.0 includes all the features and improvements of kernel version 5.15.0.

However, BSR does not support backward compatibility for higher kernels unless otherwise specified, which means that you must install a dedicated BSR package for a specific kernel version.
