Ever morning I wake up and start working around 7:30-8:00am. Every morning I start with a computer that's painfully slow, with disk activity taking forever and programs glitching all over the place. Every morning my disk is grinding hard for an hour.
I tracked it down to the fact that anacron is running cron.daily/ at 7:30 in the morning. This contains things like updatedb, mlocate, apt, mandb, logrotate, and other operations that impose significant load on the system. The *actual* crontab attempts to run these at 2:25 in the morning, which to the best of my recollection has been roughly the same time for the last 15 years. It was chosen because that's when people *aren't* using the machine for actual work.
Please explain to me why it was decided that running processes that take a long time (hours possibly) and impose a radically high system load were supposed to be run at the exact same time most people actually start using their computers in the morning???
I consider the choice of 7:30 to be a fairly severe bug (albeit trivially fixed), as it prevents every system with anacron installed from actually behaving properly.
