chroot-problem

[Gil Elad <gilelad@bezeqint.net>]

Hello,

I'm running woody with 2.4.17

for some reason I can't get chroot(8) to work. i.e. executing the 
following command (almost word for word from the info page):

$ mkdir /tmp/empty
$ cp /bin/ls /tmp/empty
$ cd /tmp/empty
$ chroot /tmp/empty /ls /

yields:

chroot: cannot execute /ls: No such file or directory


What am I doing wrong? is there a kernel config I should know about?
Any help will be greatly appreciated
