Reason for chroot failure: tmp-mksh: chroot: not found

Introduction:

I formatted a SDCard in ext4 and copied an ArchVersion on it to run it from Android like in this guide (step 6). Of course my device is rooted and am running the following scripts and commands in the Terminal Emulator as superuser.

Device-info:

• Phone: Sony Xperia Z1


• Model number: C6903


• Android version: 5.1.1


• Build Number: 14.6.A.1.236

Issue:

When I execute sh chroot_bashonly.sh the error tmp-mksh: chroot: not found appears. Of course I looked in the script to figure it out myself:

chroot_bashonly.sh:

#!/bin/sh



export LINUXROOT=/data/local/mnt

export TMPDIR=/tmp

export HOME=/root

export USER=root

export PATH=/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:$PATH

export TERM=vt100





sh ./mount.sh



echo "******* Your chroot-environment is starting now ********"

chroot $LINUXROOT /bin/bash # tmp-mksh: chroot: not found

echo "******* You exited the chroot-environment, unmounting... ********"



sh ./umount.sh



echo " ## DONE"

mount.sh:

#!/bin/sh



export LINUXROOT=/data/local/mnt

export TMPDIR=/tmp

export HOME=/root

export USER=root

export PATH=/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:$PATH

export TERM=vt100



# mount /

mkdir $LINUXROOT #works

mount -t ext4 -o noatime,rw /dev/block/mmcblk1p2 $LINUXROOT #works



# mount other stuff

mkdir -p $LINUXROOT/proc 

mkdir -p $LINUXROOT/sys 

mkdir -p $LINUXROOT/dev 

mkdir -p $LINUXROOT/dev/pts 

mkdir -p $LINUXROOT/var/lib/dbus

mkdir -p $LINUXROOT/android_storage/sdcard0

mkdir -p $LINUXROOT/android_storage/sdcard1

mkdir -p $LINUXROOT/system

mount -t proc proc $LINUXROOT/proc

mount -t sysfs sysfs $LINUXROOT/sys

mount -o bind /dev $LINUXROOT/dev 

mount -t devpts devpts $LINUXROOT/dev/pts

mount -o bind /system $LINUXROOT/system

mount -o bind /storage/sdcard0 $LINUXROOT/android_storage/sdcard0

mount -o bind /storage/sdcard1 $LINUXROOT/android_storage/sdcard1



echo "******* everything mounted ********"

I think the mount.sh part works, at least I get no error and the mkdir-created folders existing. So the next thing I tried was to run chroot outside the script in many forms with the same error.

1. chroot /data/local/mnt /bin/bash




2. chroot /data/local/mnt /system/bin/sh




3. chroot /data/local/mnt /bin/sh

All having the same issue: tmp-mksh: chroot: not found.

So what is wrong?

Is chroot even available on Android?
