Hi , guys

I am working on a server (no root permision)  , my intention is to create a
root filesystem  for arm board ,and
login as root ,directly to /bin/sh(no login window ).
>From the document , I know that it is not possible to use target/ , then I
create a rootfs.tar in images/  , and
extract it .what  I did  is as following :

(1)  "fakeroot tar -xvf images/rootfs.tar -C work/rootfs " to extract it to
rootfs directory ,
since no root permision , fakeroot does a great job.

(2) Adding  "ttyS0:respawn:~/bin/sh " to avoid requiring login .

After burning the filesystem to development board.
The problem is coming , current login is a ordinary user , what I expected
is root user .

Can someone help to fix this issue , any input would be great appreciated .
