Summary
This wiki page is the step-by-step document for build the environment of chroot for build kernel image
Install necessary package on host
host# sudo apt-get install schroot debootstrap
Where the root of chroot is
host# sudo mkdir /var/chroot
Modify the schroot config file
host# sudo vi /etc/schroot/schroot.conf
Append the following context
[hardy-lpia] description=Ubuntu hardy lpia 32 bit location=/var/chroot/hardy-lpia priority=3 users=<your_userid_on_your_host> groups=sbuild root-groups=root personality=linux32
Install basic package into chroot environment
host# sudo debootstrap --variant=buildd --arch lpia hardy /var/chroot/hardy-lpia http://ports.ubuntu.com/
host# sudo cp /etc/resolv.conf /var/chroot/hardy-lpia/etc/resolv.conf
host# sudo vi /var/chroot/hardy-lpia/etc/apt/sources.list
Remove everything and add following line
deb http://ports.ubuntu.com hardy main restricted multiverse universe deb-src http://ports.ubuntu.com hardy main restricted multiverse universe
Now you can chroot in and install more package
host# sudo chroot /var/chroot/hardy-lpia
root@chroot# apt-get install gnupg; apt-get update
root@chroot# apt-get install wget debconf devscripts dialog nano vim debhelper locales sudo kernel-wedge
root@chroot# locale-gen en_US.UTF-8
root@chroot# tzselect
root@chroot# exit
Bind several directory with chroot and host
host# sudo vi /etc/fstab
Append the following lines
Take care it will bind /home between your host and chroot environment
If you want to remove chroot environment, *umount them first*
# # Hardy-lpia # /home /var/chroot/hardy-lpia/home none bind 0 0 /tmp /var/chroot/hardy-lpia/tmp none bind 0 0 /dev /var/chroot/hardy-lpia/dev none bind 0 0 proc-chroot /var/chroot/hardy-lpia/proc proc defaults 0 0 devpts-chroot /var/chroot/hardy-lpia/dev/pts devpts defaults 0 0
host# sudo mount -a
Setup userid/password in chroot
host# sudo cp /etc/passwd /var/chroot/hardy-lpia/etc/
host# sudo sed 's/\([^:]*\):[^:]*:/\1:*:/' /etc/shadow | sudo tee /var/chroot/hardy-lpia/etc/shadow
host# sudo cp /etc/group /var/chroot/hardy-lpia/etc/
host# sudo cp /etc/hosts /var/chroot/hardy-lpia/etc/
host# sudo cp /etc/sudoers /var/chroot/hardy-lpia/etc/
host# sudo chroot /var/chroot/hardy-lpia/
chroot# dpkg-reconfigure passwd
chroot# passwd <your_userid_on_your_host>
chroot# echo hardy-lpia > /etc/debian_chroot
chroot# exit
Setup final information for dchroot.conf
host# sudo vi /etc/dchroot.conf
Append with the following content
hardy-lpia /var/chroot/hardy-lpia/
Congratulations, everything is done
host# dchroot -c hardy-lpia -d
your shall prompt shall be something like this
