Contents

Prepare chroot directory

Create directory for chroot and unpack Meego image there 

export MEEGO_ROOT="FIXME"
mkdir $MEEGO_ROOT
tar xzf <meego-image> -C $MEEGO_ROOT

Mount system directories

Mounts for chroot environment 

mount -o bind /proc $MEEGO_ROOT/proc
mount -o bind /sys  $MEEGO_ROOT/sys
mount -o bind /dev  $MEEGO_ROOT/dev
mount -o bind /dev/pts $MEEGO_ROOT/dev/pts

mount -o bind /var/lib/dbus/ $MEEGO_ROOT/var/lib/dbus/
mount -o bind /usr/share/fonts $MEEGO_ROOT/usr/share/fonts

mount -t tmpfs tmpfs  $MEEGO_ROOT/tmp
mount -t tmpfs tmpfs  $MEEGO_ROOT/var/run

Setup

Copy resolv.conf for networking 

cp /etc/resolv.conf $MEEGO_ROOT/etc/resolv.conf

Start your engines

Starting chroot 

cd $MEEGO_ROOT
chroot $MEEGO_ROOT /bin/bash

Cleanup

Don't forget to unmount all the system directories that were mounted inside chroot. You might have to setup MEEGO_ROOT again after leaving chroot. 

umount $MEEGO_ROOT/proc
umount $MEEGO_ROOT/sys
umount $MEEGO_ROOT/dev
umount $MEEGO_ROOT/dev/pts

umount $MEEGO_ROOT/var/lib/dbus/
umount $MEEGO_ROOT/usr/share/fonts

umount $MEEGO_ROOT/tmp
umount $MEEGO_ROOT/var/run
