I now have the option to decide between a n[e|o]tbooting dracut-faiclient.

If I do not provide rd_NO_LVM via tftp, then the fai-client does not boot.

If I do provide rd_NO_LVM, then fai starts (finally), but setup-storage
bugs out rather drastically [compare evidence b) ]

If I wipe the disc manually first, then there's no problem. If a
LVM-Volume exist then dracut refuses to proceed.

I tested this with 4.0.1 from Debian repository / fai-project.org and
4.0.1+0~1337780587.49~1.gbpbd6de4 from jenkins.grml.org just to make sure
there isn't already a workaround/fix in setup_storage.

disk_config is:
------------------------------------------------------------
disk_config disk1 disklabel:msdos

#part.type usage    size  filesystem  options
primary    /boot    100M  ext2        rw
primary    swap     8G    swap        sw
primary    -        4G-   -           -

disk_config lvm

vg vg_system disk1.3
vg_system-root      /         4G-12G    xfs  rw
------------------------------------------------------------
(I'm using this config for 3.4.7/3.4.8 too.)
