I would move all the tuxonice specific stuff out of do_hibernate and
into its own function like so:
do_tuxonice_hibernate() {
echo "${TUXONICE_USERUI}" > /sys/power/tuxonice/user_interface/program
if [ -n "${TUXONICE_USERUI}" ] ; then
echo "1" > /sys/power/tuxonice/user_interface/enabled
else
echo "0" > /sys/power/tuxonice/user_interface/enabled
fi
echo "1" > /sys/power/tuxonice/userui_interface/enabled
echo "${TUXONICE_EXTRA_PAGES_ALLOWANCE}" >
/sys/power/tuxonice/extra_pages_allowance
echo "${TUXONICE_USERUI_ENABLE_ESCAPE}" >
/sys/power/tuxonice/user_interface/enable_escape
echo "${TUXONICE_COMPRESSION_ALGORITHM}" >
/sys/power/tuxonice/compression/algorithm
if [ -n "${TUXONICE_COMPRESSION_ALGORITHM}" ] ; then
echo "1" > /sys/power/tuxonice/compression/enabled
else
echo "0" > /sys/power/tuxonice/compression/enabled
fi
# TuxOnIce has a separate entry for rebooting, with rebooting
# trumping powering down. We therefore explicitly disable
# rebooting when the user selects a powerdown method.
case "${HIBERNATE_MODE}" in
"platform")
echo "0" > /sys/power/tuxonice/reboot
echo "4" > /sys/power/tuxonice/powerdown_method
;;
"shutdown")
echo "0" > /sys/power/tuxonice/reboot
echo "5" > /sys/power/tuxonice/powerdown_method
;;
"reboot")
echo "1" > /sys/power/tuxonice/reboot
;;
esac
echo "anything" > /sys/power/tuxonice/do_hibernate
}
do_hibernate()
{
if [ -d /sys/power/tuxonice ]; then
do_tuxonice_hibernate
else
echo -n "${HIBERNATE_MODE}" > /sys/power/disk
echo -n "disk" > /sys/power/state
fi
}
Helps keep mental pollution down, ya know. :)

Understood. :)
