Upgrades and updates often require fetching across the network, which
can induce network delays. For other reasons entirely, I prefetch my
upgrades so they are on the computer before I start the upgrades. I put
the following into a file in /etc/cron.d:

# cron replaces the percent sign with a new line, so we escape it with a back slash.
   5      3      *                *	*	root	sleep $( echo $((1 + RANDOM \% 1200)) ) ; /usr/bin/apt-get update > /dev/null && /usr/bin/apt-get -dy dist-upgrade > /dev/null

(Pasted with long lines; your mail client may mangle it.)

You might do something similar before the automatic upgrades occur.

Does anybody read signatures any more?
