I fixed this and:

  $ ls -la /mnt/debinst/bin
  ...
  -rwxr-xr-x  1 root   root   941252 Apr 22 06:22 bash

but still:

  # LANG=C.UTF8 chroot /mnt/debinst /mnt/debinst/bin/bash
  chroot: failed to run command `/mnt/debinst/bin/bash':
    No such file or directory

Am I misunderstanding the chroot syntax? It seems the object is to run 
/mnt/debinst/bin/bash with its root being /mnt/debinst/.

I did this:

  # LANG=C.UTF8 chroot /mnt/debinst
  chroot: failed to run command `/bin/bash': No such file or directory

  $ ls /bin | grep bash
  bash
  rbash

  $ ls /mnt/debinst/bin | grep bash
  bash
