What could possible go wrong?

ubuntu-bleedingedge

#!/usr/bin/env bash
logger -t bleedingedge "### Starting automated upgrade with package update ###"
logger -t bleedingedge "(running 'aptitude update' and 'aptitude upgrade -y')"
aptitude update 2>&1 >/dev/null | logger -t bleedingedge
aptitude upgrade -y|logger -t bleedingedge
logger -t bleedingedge "## Ended automated upgrade to bleeding edge software ###"

I run this from cron.hourly of course.
