Remastersys is a tool that can be used to do 2 things with an existing Debian, Ubuntu or derivative installation.
* It can make a full system backup including personal data to a live CD or DVD that you can use anywhere and install.
* It can make a distributable copy you can share with friends. This will not have any of your personal user data in it.
The resulting ISO file can be used on any other PC that still meets the original minimum requirements of Ubuntu or Debian. Things like the graphics card and other hardware will be configured and setup automatically and you do not have to use identical hardware. Ubuntu's live boot tool, casper, currently blacklists Nvidia and AMD proprietary drivers so they will not be available on the live system and will need to be reinstalled after installation of your custom system.
Currently there is a size limitation imposed by the genisomage tool in Ubuntu and Debian. This tool is used to create the ISO file. This limits the maximum single file size for the ISO to be set at 4GB which means the entire compressed filesystem.squashfs file (your complete compressed system) must fall under this size. If it does not then the ISO file will not be created.
