Summary and Scope
Issue Type
Invoke both
mkinitrdandmkdumprd, no need for updating the bootloader.This will ensure that installing or upgrading this package will entail including this module in the existing initrd.
Currently we do this by hand by invoking the
create-kis-artifacts.shscript in our NCN builds, but in general this RPM should do this automatically.Prerequisites
