I must be since in a few hours I seem to have come up with a few modifications (all new files, no patching of existing files necessary) that achieves the goal. > That said, I'd be willing to review a detailed proposal or patch. I have yet to debianize these additional files into a formal package, but perhaps we can start with a review of the files. Big fat disclaimer though... these are based on a Ubuntu Precise system so perhaps your mileage might vary. The attachments are: /etc/init/save-kernel-for-hibernate.conf /etc/grub.d/08_linux_thaw /etc/pm/sleep.d/20_update-grub Again, maybe there are some glaring holes in this implementation, but it really is the fruit of just a couple of hours of work and testing and it works, quite wonderfully here. It was even tested as working to resume from hibernate after a kernel update was installed and resumed again, after the new kernel was fresh booted and hibernated. Cheers, b.
