Under linux, *very few* executables are stand-alone. I.e. they will
depend on libraries of different kinds. Some libraries may in turn
depend on other libraries.
$ ldd /bin/ls
librt.so.1 => /lib/librt.so.1 (0x4001d000)
libc.so.6 => /lib/libc.so.6 (0x4002f000)
libpthread.so.0 => /lib/libpthread.so.0 (0x40152000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
So for ls(1) to work, you will need the above libraries available in your
chroot'ed
environment. Other commands may depend on other libraries.
