The problem is that the kernel gives the same error "execl: /init: No
such file or directory" for a whole variety of reasons.  These
include:

 - /init missing (obviously not the case here)

 - /bin/sh missing

 - any library that /bin/sh needs is missing

 - ld-linux missing

So you need to make sure /bin/sh is there.  If it's a symlink (eg. to
dash) then the destination file is there.  Then do 'ldd /bin/sh' and
make sure all of the required libraries and ld-linux are there.
