WELCOME TO YOUR UPDATED SYSTEM THAT SUPPORTS UNIONFS \o/!
=== Create unionfs / chroot overlay filesystem for development ===
Create a 2 GB file on /home/user/MyDocs/sandbox/fs.img
  mkdir /home/user/MyDocs/sandbox/
  cd /home/user/MyDocs/sandbox/
  dd if=/dev/zero of=fs.img bs=1M count=1 seek=2048
  mkfs.ext2 fs.img
Get the shiny overlay/chroot shellscript
  wget http://metalab.at/wiki/images/d/d8/Chroot-unionfs.sh  '''WARNING the link might be different now look here: [[Bild:Chroot-unionfs.sh]]'''
  mv chroot-unionfs.sh /sbin/chroot-unionfs
  chmod +x /sbin/chroot-unionfs
This script doeas some magic including
* loading the dm-loop kernel module (for /dev/loop? devices)
* overlaying the unionfs filesystem
* mounting all needed filesystem folders inside the unionfs
* chroot()'ing inside
It is started like this:
bash /sbin/chroot-unionfs -v -t /home/user/MyDocs/sandbox/fs.img
Read the source to find out about command line parameters like -t for testing and others..
If this script is successful you should find yourself in a chrooted environment inside the unionfs
touch /CHROOTED
ls /CHROOTED    # it should be here!
exit
  ls /CHROOTED  # it should be gone!
