rsyslog incorrectly logging to /etc/messages


I have a Debian Wheezy system (3.2.0-4-kirkwood) which is logging cron messages incorrectly. The messages are appearing in /var/log/cron but also appearing in /var/log/messages.

If I understand rsyslog.conf correctly, the earlier rules specific to cron, e.g., "if $programname contains 'cron' then ..." should override default logging, and the tilde action should stop rsyslog evaluation at that point so that no default logging occurs.

I'd be glad if anyone can offer insight into this issue.

-------------------------------

tail /var/log/messages:

Jul 28 12:43:01 /USR/SBIN/CRON[18940]: (root) CMD ( ntpdate -s 0.us.pool.ntp.org)
Jul 28 20:43:01 /USR/SBIN/CRON[18951]: (root) CMD ( ntpdate -s 0.us.pool.ntp.org)

This works for me:

Code:
# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none                /var/log/messages

# Log cron stuff
cron.*                                                  /var/log/cron
I think cron is a built-in facility, not just a program name, so it may be handled specially.

Works perfectly. Thank you; this one had me scratching my head for the last week.
