Comment # 31 on bug 1226122 from Josef Reidinger

well, I would say it is not installer fault that it stop working. We do not
directly require those packages, especially if no bootloader is selected. What
installer did in that case is basically nothing, just install other packages.
If it is needed to have tools-scriptlets installed in that case it should be
manually selected as installer cannot know what is needed in case no bootloader
is required.

Lets just reassign to Martin Wilck to double check that the change caused by
adding sdbootutil-rpm-scriptlets are intentional.
