For those who don't know, unetbootin is a tool for making a bootable USB flash drive from an iso.

Is it possible to create a partition, back up your "perfect system" with remastersys, and use unetbootin to create a recovery partition?

The partition would be accessed through Grub, and would offer an easy way to restore the system to "factory" settings, especially on a system without a CD drive, such as a netbook.
