Public bug reported:

Binary package hint: cron

I have 36 virtual containers and while not all of them have cron
installed, there is a significant load at peak times, caused by the
periodic cron script (e.g. "apt-get check" via /etc/cron.daily/apt).

The idea would be to either randomize this by adding a random amount of
time to a given offset, or use other means like the machine's IP address
to spread it (e.g. by specifying "R" instead of "*" in the crontab
entry).

There is a bug files in Debian already which contains some discussion.

cron should randomize /etc/crontab to be more friendly to virtual servers
