Here is a basic script that warns the user that the system is
about to a do normal boot while a resume partition is present,
giving a chance for a "manual recovery resume" for experienced
users. (The script will not work for swap files or for tuxonice.)
#!/bin/sh

# Initramfs-tools boot script:
#
# Warn the user if partition(s) with swsusp signature remains even after the
# resume/uswsusp boot scripts have run. This script is only for kernel swsusp
# and userland uswsusp (not for tuxonice, sorry).
#
# Put this script where the resume/uswsusp boot scripts are kept.
# USE AT YOUR OWN RISK.
