nexus-7-2013-arch-scripts

A set of scripts to manage an Arch Linux chroot on the 2013 model Nexus 7

Prerequisites

A rooted Nexus 7 (only 2013 model tested).

Initial install

Clone the repo and get inside:

local $ git clone https://github.com/borh/nexus-7-2013-arch-scripts.git
local $ cd nexus-7-2013-arch-scripts

From here on out, the following naming conventions wil be used:

• local: your local machine
• nexus7: inside the Nexus 7 Android environment
• chroot: inside the chroot (Arch) inside the Nexus 7 Android environment

Copy the install script and get an android shell:

local $ adb push install-arch.sh /sdcard/
local $ adb shell

Install arch:

nexus7 $ su
nexus7 $ sh /sdcard/install-arch.sh

chroot script

local $ adb push chroot.sh /sdcard/

To enter as root:

nexus7 $ su
nexus7 $ sh /sdcard/chroot.sh root

To enter as user XYZ (after you have created a user, as detailed in the next section):

nexus7 $ su
nexus7 $ sh /sdcard/chroot.sh XYZ

Adding users

Add user XYZ:

chroot $ export USER=XYZ
chroot $ useradd -m -g users -s /bin/zsh ${USER} # or /bin/bash...
chroot $ usermod -aG inet ${USER}
chroot $ usermod -aG inetadmin ${USER}
chroot $ usermod -aG aid_inet ${USER}
chroot $ usermod -aG wheel ${USER}
chroot $ visudo # uncomment %wheel ALL=(ALL) ALL

VNC script (Standalone)

chroot $ mkdir ~/.vnc
chroot $ cp /media/sdcard/xstartup ~/.vnc
chroot $ cp /media/sdcard/init-vnc.sh ~/
chroot $ vncpasswd # set password VNC
chroot $ ~/init-vnc.sh

Before starting the VNC server, we want to configure dwm:

chroot $ cd nexus-7-2013-arch-scripts/builds
chroot $ sudo pacman -S yajl && cd cower && makepkg -i && cd ..
chroot $ sudo pacman -S expac && cd pacaur && makepkg -i && cd ..
chroot $ cd dwm && makepkg -i && cd ..

VNC Client

Recommend downloading and installing androidVNC from here: http://dl.dropbox.com/u/13927052/androidVNC-branch_antlersoft_eeePadBuild_004.apk

Settings for software keyboard:

• 'Hacker Keyboard' from Play Store

Settings for hardware keyboard:

• 'Tweaked Keyboard Layout' from Play Store
• With androidVNC, the "Mouse Pointer Control Mode" passes through most of the keys

Most of the hard work on installing Arch (chroot) on android has already been done by others. These are just some of my personal modifications to their work.
