As Baruch suggested, using "cp" for this purpose is no good.  Refer to the buildroot manual and the warning file installed to the
target dir:

http://buildroot.uclibc.org/downloads/manual/manual.html#_nfs_boot
http://git.buildroot.net/buildroot/tree/support/misc/target-dir-warning.txt

Hi all

Right, until now I always used a post script that extracted the rootfs.tar.
So I tought I could integrate this into br.

And yes, I run linux in a vm and am to lazy to create a user and use sudo,
so on my virtual linux machine, I am always logged in as root.
