[CentOS] Yum-updatesd

Finsihing my server set up..
Yum-updatesd

This is on, via the chkconfig and seems to run a lot.

TO DO: auto update YUM for the computer once a day.
Files: /etc/yum/yum-updatesd.conf
Extra: send a mail or add to log file

This is the centos original file and my suggested changes.
If anyone uses this, do you have something similar?

[main]
# how often to check for new updates (in seconds)
run_interval = 3600 (gonna change to 86400 for 24 hours)

# how often to allow checking on request (in seconds)
updaterefresh = 600 (leave as is)

# how to send notifications (valid: dbus, email, syslog)
emit_via = dbus (change to email, defaults to root I believe)

# should we listen via dbus to give out update information/check for
# new updates 
dbus_listener = yes (assume no?)

# automatically install updates
do_update = no (change to yes)

# automatically download updates
do_download = no (change to yes)

# automatically download deps of updates
do_download_deps = no (change to yes)


I am not sure about the dbus listener. The documentation, yum wiki, or the
man pages were not telling me anything.

Thanks
