Actually... If you could add

printk(KERN_ALERT "Hibernation image written. If you have any
filesystems mounted read-write and attempt to resume, you'll corrupt
your data. To prevent that, remove the hibernation image.\n")

...I guess that would save someone's filesystem. (Yes, very high
loglevel. If you attempt to do this from anything else then singleuser
or initrd, you are asking for problems, so... lets make sure user sees
it.)

Thanks,
