It doesn't _have_ to be done on boot, either. It's essentially done to make sure the system wasn't just powered down when the disk's were still active. In the case of a successful hibernation, that can't happen - if the disks weren't synced, there won't be a valid hibernation partition, and on power-up you'll end up doing the full cold start. > There's an (experimental) 'kexec-call' option to switch kernel on-the-fly. > I hope this will work well some day, at least in defined environments. > Imagine to compile anything on demand within the running system some > day....
