Public bug reported:
If one updates one's kernel, which causes the default kernel pointed to
by grub to change, a system will not be straightforwardly resumable from
hibernation. This is because when one does power back on, the kernel
that will boot by default will not be the same kernel the on-disk
hibernation image is for. One needs to be careful to boot the kernel
that was booted when the system was hibernated -- if one even knows what
that was.
It seems to me to be entirely useful that when you hibernate a system,
the kernel and initrd that were booted at the time of hibernation are
stashed away and a new, temporary grub menu item is created clearly
indicating that it's for resuming of the hibernated image.
This framework should also be careful to stash the on-disk image of the
running kernel if the package providing that image is removed from disk.
In fact, perhaps it should be not allowed to remove the package
providing the running kernel to prevent this situation.
