LVM not working.

[Thomas Lange]

OK, I've solved this problem. I seems that the old CENTOS7_64.tar.xz
basefile in http://fai-project.org/download/basefiles/ caused all the
problems. I've created a new one, which now works.

Using this patch, you can now add the FAI class LVM to your CentOS
install client and use a LVM partitioning with CentOS 7.
