[oe] why rootfs directory in temp is empty

[Guo Hongruan]

Hi guys,
   Today, I build an base-image using OE. And I want to check the content  
of rootfs, but I found the directory rootfs in building directory is  
empty. I remember there was the ontent of the target root filesystem. Why  
have to remove them? Does it means the rootfs directory is unuseful?

Thanks a lot!
