There might be a future with the VR unlike the K1.
I have never chroot into an arm emulator. I have chroot from a 64bit into a 32bit OS. I have chroot from mips video player with android to mips debian. Here I do a virtual chroot so I don't need to bind mount things except that should be virtually the same anyway.
Here I start from /bin/bash and chroot to /bin/bash, /bin/sh (dash) and /bin/busybox sh (ash). Notice how the prompt changes with the various shells. I don't know if your box has dash. Just try changing the SHELL environment setting as shown here.
Code:
root@delldebian:/tmp#
root@delldebian:/tmp#
root@delldebian:/tmp# echo $SHELL
/bin/bash
root@delldebian:/tmp# chroot /
root@delldebian:/#
root@delldebian:/# exit
exit
root@delldebian:/tmp# SHELL=/bin/sh
root@delldebian:/tmp# chroot /
#
# exit
root@delldebian:/tmp# chroot / /bin/sh
#
# exit
root@delldebian:/tmp# chroot / busybox sh
BusyBox v1.20.2 (Debian 1:1.20.0-7) built-in shell (ash)
