Everything that could be moved was moved under /var, because it's the last directory (alphabetically) on /.
You will have to invoke the dynamic loader by hand in this case, because it has been moved as well. On Debian GNU/Linux 64-bit, you can find it at /var/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2. You will also have to set LD_LIBRARY_PATH accordingly, otherwise the binary to be executed will not be able to find its required libraries (mainly libc.so, in this case):
# export LD_LIBRARY_PATH=/var/lib/x86_64-linux-gnu # /var/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 /var/bin/ls
You can now invoke 'mv' and move the contents back to /.
Congratulations. You know your dynamic loader. :) This particular system is yocto multilib based, so it was /var/lib64 that had the needed files, and mv happens to be in busybox with a symlink pointing the wrong way so it needed busybox called explicitly with mv as an argument, but that wasn't the important part. -- Len Sorensen
