The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare git@github.com:usi-systems/easytrace.git

#!/bin/bash

set -xe
# This script takes as a parameter the name of the VM
# and creates a linked clone
# Ref: https://unix.stackexchange.com/a/33584
# The scripts assumes that it runs from the same folder 
# where the vm image is located and it coincides with the 
# image name
