As for existence of /bin/bash in reference to new chroot:
$ ls -la /mnt/debinst/bin | grep bash
-rwxr-xr-x 1 root root 941252 Apr 22 06:22 bash
As for libraries, bash needs these:
$ ldd /bin/bash
linux-gate.so.1 => (0xb773e000)
libtinfo.so.5 => /lib/i386-linux-gnu/libtinfo.so.5 (0xb7702000)
libdl.so.2 => /lib/i386-linux-gnu/i686/cmov/libdl.so.2 (0xb76fe000)
libc.so.6 => /lib/i386-linux-gnu/i686/cmov/libc.so.6 (0xb7599000)
/lib/ld-linux.so.2 (0xb773f000)
So I create directories and copy libraries to them. I didn't understand
the first line and apparently there is no linux-gate.so.1 on my
system. Other than it, I now have:
$ ls /mnt/debinst/lib
i386-linux-gnu ld-linux.so.2
$ ls /mnt/debinst/lib/i386*
i686 libtinfo.so.6
$ ls -la /mnt/debinst/lib/i386*/i686/cmov
...
-rwxr-xr-x 1 root root 1446056 Apr 22 08:47 libc.so.6
-rw-r--r-- 1 root root 9844 Apr 22 08:49 libdl.so.2
Now chroot command has better luck:
# LANG=C.UTF-8 /usr/sbin/chroot /mnt/debinst/
bash-4.2#
I guess copying over the libraries was the answer. However, my chroot
prompt used to appear as: root@hostname:/#, so I'm not sure I'm in
chroot.
