This procedure (for Debian, Ubuntu, and derivatives) is useful when need to create a template, and your host hasn't suite's script (in /usr/share/debootstrap/scripts). This situation can de caused because your host and your next template are from different distributions, or because your host is an older version than the next template you want to create (fo example, creating Ubuntu 10.04 template in an Ubuntu 8.04 host).
To do this you need a computer to install a clean system or a virtual one with Qemu or similar.
Step 1: install a system with the distribution & version you want for template
We will call it the "satellite system". You can do it also with another already installed computer with the same distribution & version you want.
Step 2: debootstrap (in satellite system)
cd /tmp sudo apt-get install debootstrap mkdir newsystem # The parameter --variant=minbase is optional. You may want it to make a minimal template. sudo debootstrap --variant=minbase $(lsb_release -cs) newsystem
Step 3: package for moving
cd newsystem sudo tar czf /tmp/debootstrap_$(lsb_release -is | tr "[:upper:]" "[:lower:]")-$(lsb_release -rs)-$(uname -m)_minbase.tar.gz . cd .. sudo rm -R newsystem
Now you have a package like "debootstrap_ubuntu-10.04-i686.tar.gz" to copy to the OpenVZ host/server.
Unpacking for a new templaye (example for 777 container, in the OpenVZ server)
sudo mkdir -p /vz/private/777 cd /vz/private/777 sudo tar xf /tmp/debootstrap_ubuntu-10.04-i686.tar.gz
Next steps are the usual for creating a template.
