- suppress cpio blocks message to stderr
- use global variable kernel_cmdline to store paramters
  passed to the linuxrc/init script and don't hand them
  over via sub-functions
- fixed corrupted fbiterm fonts for openSUSE 12.3 (bnc #803276)
- fixed start/stop of udev in pre-init. while using sysV init
  it was possible to run a startup script without a running
  init process. With systemd you cannot really run a service
  when systemd does not run
- don't rely on boot.device-mapper init script, load
  device mapper module manually when needed
