http://bugzilla.opensuse.org/show_bug.cgi?id=1195291 Bug ID: 1195291 Summary: initrd is being rebuilt when kernel is being removed after kernel update Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.3 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: Ulrich.Windl@rz.uni-regensburg.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Despite of the problem that initrds are needlessy rebuilt when installing kernel modules (bug 1100885, bug 1191322), there are also needless rebuilds when removing obsolete kernels: Still on the next boot when older kernels are removed, their initrds are being rebuilt before the kernels are removed (it seems at least).
