CENTOS with LVM layout

[Antanas Masevicius]

also tried with some older basefile:
http://fai-project.org/download/basefiles/CENTOS7_64.tar.xz

lvm is still not being added:

ainsl: appending to /target/etc/fstab: sysfs    /sys    sysfs   auto
     0 0                                                          [0/1806]
ainsl: create /target/etc/dracut.conf.d/fai.conf
ainsl: appending to /target/etc/dracut.conf.d/fai.conf: filesystems+="ext4"
No '/dev/log' or 'logger' included for syslog logging

CENTOS/30-mkinitrd   OK.


checked for lvm binaries in /target, looks like binaries are in place.
