Are there any cases where having anacron installed by default would mess something up?I would not like to have it on 7/24 servers. There could be problems after longer power outages in combination with weak scripts (which use dates as file names). But this "should be the minority". And such logic will even have problems without anacron.
Anacron provides protection against running cron jobs a second time due to a reboot or power outage. The first task in cron.(daily|weekly|monthly) runs anacron -u cron.(daily|weekly|monthly). This updates anacron's last run timestamp with the current date. When anacron next runs at boot, it will only run the tasks using anacron if a day, week or month have elapsed since the last timestamp was written.
