| + | ===== Debian in chroot on Android ===== | ||
| + | <note important>This works with Debian Jessie and does not work with Debian Stretch. APT HTTP method says that it cannot create socket, permission denied. Adding user to the inet/net_raw group does not help. It might be caused by the old 3.4 kernel.</note> | ||
| + | |||
| + | Automated tool: [[https://guardianproject.info/code/lildebi/|Lil' Debi]]. | ||
| + | * Uses fixed-size loopback device. | ||
| + | * Requires free loopback device - does not work on CyanogenMod 11 on Nexus 4. | ||
| + | |||
| + | Manual installation: | ||
| + | * Install with --foreign on a non-ARM computer | ||
| + | <code>debootstrap --arch=armhf --foreign jessie armroot/ http://ftp.de.debian.org/debian | ||
| + | cp /usr/bin/qemu-arm-static armroot/usr/bin/ | ||
| + | chroot armroot/ | ||
| + | /debootstrap/debootstrap --second-stage</code> | ||
| + | * Transfer armroot/ to the device /data/armhf | ||
| + | * First-time usage after reboot: | ||
| + | <code>su -c "mount -t tmpfs -o context=u:object_r:fuse:s0 none /storage/emulated/legacy/DCIM/OpenCamera/foo" | ||
| + | su -c "mount -o bind /dev /data/armhf/dev; mkdir /data/armhf/system; mount -o bind /system /data/armhf/system; mkdir /data/armhf/aroot; mount -o bind / /data/armhf/aroot; export LD_PRELOAD=; export HOME=/root; export TERM=xterm; mount -o bind /mnt/shell/emulated/0/ /data/armhf/storage; chroot /data/armhf /bin/bash" | ||
| + | </code> | ||
| + | * Unexporting LD_PRELOAD from the above example is needed on Android 5 and does not work on Android 6. | ||
| + | * Next shell: | ||
| + | <code>su -c "export LD_PRELOAD=; export HOME=/root; export TERM=xterm; chroot /data/armhf /bin/bash"</code> | ||
| + | * Useful .bashrc: | ||
| + | <code>export PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/root/bin" | ||
| + | |||
| + | cd /root | ||
| + | |||
| + | /etc/init.d/ssh start >/dev/null 2>&1 | ||
| + | |||
| + | mount | grep -q proc || mount -t proc none /proc | ||
| + | mount | grep -q devpts || (mount -t devpts none /dev/pts; mount -t sysfs none /sys) | ||
| + | export LANG=cs_cz.UTF-8 | ||
| + | export LANGUAGE=cs_cz.UTF-8 | ||
| + | [ -e /root/vault/pin ] || encfs /root/.vault /root/vault | ||
| + | </code> | ||
| + | * My favorite terminal emulator: https://f-droid.org/repository/browse/?fdid=jackpal.androidterm | ||
