Poor Man's Debian Mirror

I'm not sure if I've posted this before, but if you Debian users drop this in root's crontab, you'll save a whole lot of download time:

# cache latest packages at 5am
1 5 * * * apt-get -q update && apt-get -qfmuy --download-only dist-upgrade

That'll cache the latest packages every morning. This isn't my idea, I stole it from Tom (giblet), and I have no idea who he stole it from.
