    initrd/rc: mount initrd ro; set PATH, HOME, NEW_ROOT; cleanups
    
    * The initrd is mounted readonly by default, do not upgrade to be readwrite.
    
      NOTE: This may cause problem with diskless boot (/etc/rc.d/diskless) and
      needs further tests and tunes (Thanks to ftigeot).
    
    * Set PATH=/bin:/sbin to simplify the command invocations.
    
    * Set HOME=/var/home (Suggested-by: ftigeot)
    
    * Set NEW_ROOT=/new_root that will be used in the mount scripts.
    
      Make sure that the NEW_ROOT directory exist, otherwise try to remount the
      initrd / readwrite and create it.
    
    * Various cleanups to make it much simpler and cleaner.
    
    * Also clean up the rc.lvm2 a bit.
