Writing crontab with Cheetah
============================

This example randomizes the time of cron.daily
execution with a stable result. Cron.daily is run at a consistent,
randomized time between midnight and 7am.::

    #import random
    #silent random.seed($self.metadata.hostname)

    # /etc/crontab: system-wide crontab
    # Unlike any other crontab you don't have to run the `crontab`
    # command to install the new version when you edit this file.
    # This file also has a username field, that none of the other crontabs do.

    SHELL=/bin/sh
    PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin://bin

    # m h dom mon dow user  command
    17 *    * * *   root    run-parts --report /etc/cron.hourly
    $random.randrange(0,59) $random.randrange(0,6)    * * *   root    test -x /usr/sbin/anacron || run-parts --report /etc/cron.daily
    47 6    * * 7   root    test -x /usr/sbin/anacron || run-parts --report /etc/cron.weekly
    52 6    1 * *   root    test -x /usr/sbin/anacron || run-parts --report /etc/cron.monthly.
