That is EADDRINUSE and is expected if the socket already exists (so
you'd need to rm /tmp/foo in my example, or modify it to unlink the file
first).

The human readable error you get when running in a chroot is 'Cannot
assign requested address' when /tmp/foo does not exists (otherwise
you'll get EADDRINUSE as well), having /tmp/foo in the main root or not
does not matter in this case.


Sorry for being unclear,
