[[3w`Sparky]]

I want to install some packages to a hdd from booting a live cd

eg add something lets say gparted for example to the hdd install of ubuntu

but

while i'm booted from a live cd or if the disk has been put into another linux box

You can chroot into an existing Linux installation:

mount the root ("/") partition:

sudo mkdir /var/chroot
sudo mount /dev/sda1 /var/chroot



mount the virtual filesystems & enable the network:

for i in dev dev/pts proc sys etc/resolv.conf; do sudo mount --bind /$i /var/chroot/$i; done


type:

sudo chroot /var/chroot su - username
to change to a shell inside the chroot.
NOTE: you are logging in as user: username.


inside the chroot install the application(s) or run any other command:

sudo apt-get update
sudo apt-get install gparted

to run a GUI application:

allow your user to connect to the X server & run the GUI app:

outside the chroot type:

xhost +SI:localuser:username
inside the chroot run the app:

sudo synaptic

OR


run the application(s) in a separate window:
outside the chroot type:

Xnest -ac :2
inside the chroot type:

export DISPLAY=127.0.0.1:2.0
start a window manager:

metacity &
run an application, i.e the panels:

gnome-panel &> /dev/null &


exit from the chroot:

exit #or press Ctrl+d
