LS,

I have an issue with chroot in the next context:

qemu-aarch64 -cpu cortex-a53 -L /newroot /newroot/usr/sbin/chroot /newroot \
  /usr/bin/env -i \
    HOME=/root \
    TERM="$TERM" \
    PS1='(arm chroot) \u:\w\$ ' \
    PATH=/usr/bin:/usr/sbin \
    /usr/bin/bash --login +h

qemu-aarch64 is running on top of x86_64 linux and chroot, env and bash 
are compiled as aarch64 binaries.
By themselves they all run under qemu-aarch64. But when using the above 
command, it always fails with 'Exec format error'. The same if running:

qemu-aarch64 -L /newroot /newroot/usr/sbin/chroot /newroot

It should run /bin/bash, but ends with the same error message.

Running 'qemu-aarch64 -L /newroot /newroot/usr/bin/bash -c /usr/bin/env 
--help' does show the env help text. So, I guess chroot is to blame?

Regards, Frans.
