Perl-Bootloader response for kernel post-install bootloader update script. Current target is ensure, that you have in your bootloader actually kernel and also that entries for old kernel is removed. This is problematic for some complex or manually enhanced configuration. In this case perl-Bootloader should somehow break your settings (this mean you still can boot, but your enhancement or extra sections can dismiss). This should change in future as noticed in bugzilla .

If you want maintain your configuration manually, you can simple set your bootloader to none. There is two ways how you can do it. First is set LOADER_TYPE=”none” in /etc/sysconfig/bootloader. Second is set this in yast2 bootloader. Another advantage is that this take almost no-time, so if obtain hardware configuration for update take to much time, this is workaround.

Warning, if you set bootloader type to none you must manually edit your bootloader configuration after kernel update. What can help you, is set image and initrd to symlinks which lead to actual kernel.
