Hi , Thomas

We have an internal jffs2 image making process , which requires a pure
target from buildroot ,
and follow the steps as below :

(1) extract rootfs.tar to designated target directory (rootfs) , this is
done by post-script .
(2) Adding functional script and application to rootfs .
(3) make a new jffs2 image
(4)burn this image to arm board

Of course , if extract rootfs.tar as root , everything works pretty well ,
busybox login as root .
But in the server , there is no root permission .

So the issue is how to login as root without "operation of extract
rootfs.tar as root".

Regards ,
