Once I get remaining commits pushed (not all of them yet are), the image can be installed by typing: sudo npx @puu/install The TUI installer duplicates the bootc image of the live ISO to the target hard drive. It has a checkbox for hibernate as part of the installation flow. I'll report the results later, and at that time my testing harness should be fully available in public. I think this is pretty much the lcd for the required testing machinery. It is neither a feature very popular nor well maintained among popular Linux distributions. Br, Jarkko
