Well, you'll need to unpack the tarball as root in order to create the
device nodes and get the permissions right on stuff like /etc/passwd -
If you do that, you shouldn't need to do any additional chown.

Ok.

Ahh, so probably date gets to run just fine, but you just don't see
any output.

Do you have a /dev/ttyUL0 device node (c 204 187)? Are you running a
getty on it? (A ttyUL0::respawn:/sbin/getty -L ttyUL0 115200 vt100
line in /etc/inittab)
