    The article won't help, however... It is not nearly detailed enough for learning anything. For the recent immigrants from Windows, it is a great roadmap.
  2. Ubuntu's fast resume patch for grub by schwaang · · Score: 3, Interesting
    By way of making lemonade, here's a post by an Intel engineer to ubuntu-kernel-devel about a proposed grub patch that would make resuming from hibernation much faster:

    Below is the work theory of our "grub fast resume" patch
    The normal swsusp2 resume process is:
    "grub" -> "kernel" -> "initrd" -> "resume from the hibernate"
    Our "grub fast resume patch" can work as below:
    "grub" -> "resume from hibernate"

    Our "grub fast resume" patch can resume the saved hibernation image from
    grub directly that will save much time to load and run kernel and
    initrd. The patch does not change any kernel code.


    [I use hibernate on Fedora all the time, so I'd love to see a patch like this go in to Fedora's grub. Thing is, the patch is apparently based on swsusp2, and I'm not sure Fedora's kernel uses the swsusp2 version of hibernation.]

    In a reply to the post, a debian guy points out that grub is legacy at this point, and that they are looking to move to grub2.
