[NEW] Anacron: A cron-like periodic command scheduler

Anacron is a sheduler that is useful for system which are not continuously running (ex. laptops).  Add anacrond in the DAEMONS list in rc.conf.  The anacrontab file is set-up to run the crond jobs. Any comments would be appreciated.

Re: [NEW] Anacron: A cron-like periodic command scheduler

There is a "bug" in the anacrontab file.    The delays were really slowing the boot time. No delay would be better for the deamon. 

The new anacrontab:

# /etc/anacrontab
SHELL=/bin/bash
# format: period delay job-identifier command
1        0      cron.daily      run-cron /etc/cron.daily
7       0      cron.weekly     run-cron /etc/cron.weekly
30     0      cron.monthly    run-cron /etc/cron.monthly

Why you not use

    /usr/sbin/anacron -s

in the /etc/rc.d/anacrond file ?
