This is an extension of my initial question, for I'm not sure my initial conclusion that it is impossible to chroot a 64bit system from a 32bit system is correct.
Can it done by installing qemu-user-static and loading a 64-bit live ISO and then from it chroot the 64-bit target mounted on /mnt/64bit/? Or can chroot be run on a 64 bit system mounted on /mnt/64bit/: # dpkg --add-architecture amd64 # apt-get update # apt-get install libc6-amd64 # LANG=C.UTF-8 chroot /mnt/64bit /bin/bash Haines Brown
