> You can’t hibernate an OS and swap out all the hardware and expect it to actually wake back up. You’re going to have to do a full boot. Have you actually tried? You sound like you're used to Windows where if you change a single piece of hardware the whole OS goes to pieces and needs to be re-installed or go through a painful process of driver searching. Considering I can (and have) literally moved hard drives between vastly different generation machines (granted, they were the same architecture), I don't think it's that far fetched to imagine Linux might actually resume from a hibernate with no issues on different machines. I've got some spare time this weekend, and I might just have to test this theory. Even if it doesn't work out, my experience with swapping hardware in Linux leads me to believe it wouldn't be that hard to add support for resuming from hibernate on different hardware. Sounds like a good college senior CS project to me. |

Haha I didn't come here to be a win fanboy, but have you ever actually done this? I build all my own machines and I have removed a windows boot drive from a system, replaced the motherboard and all major components, put the drive back in and booted successfully without making any changes at all. I've done this on NT, XP and 7. Have not yet done it on 10. Some things will definitely not work right, and you will for sure have to update some drivers, but in all likelihood it will boot. It helps if you uninstall the board-specific drivers (chipset, etc) prior to the teardown, but I have done it both ways.
