Modified refractasnapshot to make a snapshot of a system other than the one you're running. The snapshotted system only needs live-boot* and live-config* packages installed. The refractasnapshot deps and the script only need to be installed on the host system.
Works on a mounted filesystem or a directory where you did a debootstrap install. It does not ask any questions - all variables are hard-coded, so it can run automatically.
It assumes that you have refractasnapshot and its dependencies installed, so it can use /usr/lib/refractasnapshot/iso as a source of files for the isolinux directory in the live media. You can change that. Check the variables in the head of the script before you run it.
Here's the script and the excludes list.
