# Remove daily cron optional with above changes to default

# It creates the repository configuration file for package updates, and it
# monitors that config to see if it has been disabled by the overly aggressive
# distro upgrade process (e.g.  intrepid -> jaunty). When this situation is
# detected, the respository will be re-enabled. If the respository is disabled
# for any other reason, this won't re-enable it.
#
# This functionality can be controlled by creating the $DEFAULTS_FILE and
# setting "repo_add_once" and/or "repo_reenable_on_distupgrade" to "true" or
# "false" as desired. An empty $DEFAULTS_FILE is the same as setting both values
# to "false".
