Well y2log-1 is showing that mkinitrd/dracut is consuming this time.

The question is why it takes so long.
BUT: mkinitrd will called twice:

1. RpmPostTransCollector.cc(executeScripts):122 EXECUTE posttrans:
   coreutils-8.29-lp151.9.20.x86_64.rpm9k7mkD
2. YaST2-Bootloader module 

So the consuming time will be doubled. As there are two different ways how
mkinitrd will be called here (and in both cases the call is time consuming) I
have doubts that it depends on the installation mode (text/graphical).

So Daniel, why it takes so long ? Perhaps the QA can give you a machine where
you can call mkinitrd in a console ?

Josef, do we really need the mkinitrd call twice ? Perhaps we can distinguish
between an running installation/update and the bootloader call in the running
system ?
