Initramfs rebuild not triggered automatically when KMP is installed

This document (000020379) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 15 SP3

Situation

Initramfs rebuild is not triggered automatically when KMP driver modules are installed.
As a result, the initramfs does not include the newly installed drivers.

Resolution

The suse-module-tools update version 15 released July/2021 includes the fix for the problem.

Workaround:
One of the following options could be used to work around the issue:

After installing a KMP:
1. Rebuild initramfs manually using 'dracut -f'

Two ways to resolve it in the KMP itself:
2. Pass the –b option to %suse_kernel_module_package in the KMP spec file:
%suse_kernel_module_package trace -f %{SOURCE1} -b
This enforces an initrd rebuild.
3. Use xz compression in the KMP, for example: find $RPM_BUILD_ROOT/lib/modules -name '*.ko' | xargs xz
