Hi Andrea. Was the file system extracted from the archive as root to preserve the ownership and permissions? Is the export of the file system allowing root access (norootsquash).
The error is pretty clear that the init isn't executable and neither is the shell, so I suspect your file system that's being mounted isn't right, or is being mounted in such a way as to revoke root privileges.
