I don't think the journal replay would actualy be written to hte FS. As
I understood the changelog item, it would only be used to read the files
grub uses with the advantage of journalized FS. Maybe a special module
could be written to allow actually applying the changes to the FS, to
recover - say - a broken kernel image.

For 3) I don't know enought about hibernation.
