Yes. All the cron scripts do is to execute yum-cron with an optional config script as an argument; if no config file is given, it uses the default (/etc/yum/yum-cron.conf). 'man yum-cron' tells you this. > > I only really need yum-cron to run once a day, which would be > sufficient.

The scripts in /etc/cron.daily are run via anacron with a configuration file of /etc/anacrontab. The exact time the jobs are run are not specified and are variable depending on what the machine is doing (and a random delay). But you can impose time limits on when the jobs can be executed. cron.hourly is different and executed via the normal cron system (config is in /etc/cron.d/0hourly) P. _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
