Boot the system target system from some sort of Linux live CD 2. Build the on disk file system layout 3. rsync the files from the source system to the target system 4. customize configuration files on target machine to account for any hardware differences 5. install the boot loader 6. Profit! Approach 2: 1. Start with a fresh install of your favorite distro on the target machine 2. Install the application 3. Copy over the application configuration and data 4. Profit! If you were doing it with virtual machines you would just need to copy over the virtual disk and virtual machine configuration files. - Bill
