Some distros, including debian unstable with 2.6.30, still shop
style ide drivers and/or have important filesystems like ext3 as
modules.
This patch ensures that all test cases work on these configurations
by including the necessary modules and adding a simple udev rule
file that provides /dev/sd* symlinks for the case where old style
ide drivers are still in use.
Copy /etc/mdadm.conf to initramfs (even for non-hostonly) if
mdadmconf="yes" is set in dracut.conf or --mdadmconf is specified on the
dracut command line.
This was done, because there seems _no_ sane way to autoassemble md raid
arrays.
also moved rd_NO_MD to an udev ENV
