dracut error

["Hannu T. Pysäys"]

Hi again, 

I’m trying to install CentOS 7 (with md software raid1). 
So far I always get following error:

fai.log:/sbin/dracut: line 600: cd: /lib/modules: No such file or directory

It looks for me that in my config/scripts/CENTOS/30-mkinitrd tries to do
both CentOS 7 and CentOS 6 ails-commands (at least I get two rows to /etc/dracut.conf.d/fai.conf)

Any clues of this?

br, Hannu
