This is the [syntax] I use:
LANG=C.UTF-8 chroot /mnt/cin /bin/bash
/mnt/cin was my easier to type and remember alternative to /mnt/debinst.
Gets it done for me every time. It was just a twist on what I'd found
on the Net when I first taught myself that part of Debian (for
debootstrap installations). I'd never *thought* about how or why it
was doing what it was doing until reading through this thread...
Are you all saying that it starts looking for /bin/bash AFTER it's
inside the chroot session?
I started to say: "If the answer to that question is yes, then what's
happening with the failed /mnt/debinst/bin/bash is that the
/mnt/debinst path in fact does *not* exist to your target chroot
session once you're inside chroot. That aspect of the process was hard
for my brain to wrap itself around originally after a few years's
worth of experience where anything Linux was able to access anything
else it wanted."
BUT: After thinking yet that much harder on this, maybe there's some
magic command that a fellow user knows that changes that. The
potential for such a command never occurred to me because I had no
driving need for it. I could always complete what was needed by simply
switching between terminals that represented a latest shiny, new
deboostrap install and its old, worn out, "cruft" filled predecessor.
Just now the thought crossed my mind that maybe some chroot sessions
do in fact demand the ability to access the outside World depending on
their purpose along with what's already installed. Since you're
working with /mnt/debinst, I'm a-suming this is potentially a
phenomenally basic deboostrap install attempt because I remember being
instructed to create that same directory for my own original
debootstrap attempts.
Good luck!
