Comment # 2 on bug 1182318 from Takashi Iwai

The installation integrity is a general problem of rpm, but for the kernel
installation, it's more serious because this is the most bast part of the
installation.

The second proposal sounds promising, it also relaxes the blockage by the
package installation.  So this means that we'll have a system service that
(re-)creates the initrds.  It can be set to finish before shutdown /
hibernation, too.

Actually we can do both proposals; those are not exclusive.  The worst case is
to boot a broken kernel installation.  I guess an alternative to the first
proposal is something like: at package installation time, put the kernel as
some invalid file name like /boot/xxxvmlinuz-*, then rename it to a proper name
/boot/vmlinuz-* once after the initrd is created, and run grub2-mkconfig.
