As a result of the distribution crontab, /usr/libexec/atrun was being run only once an hour instead of every five minutes. This was due to a minute specification of 0/5 -- which should have been */5. This has been fixed. Expect your /var/cron/log to grow much faster now. 1994-04-15 16:57:38 +00:00			`# /etc/crontab - root's crontab for FreeBSD`

This is Vixie cron 3.0. This version fixes all known security bugs. Further it implements crontab -e. I moved cron from /usr/libexec to /usr/sbin where most daemons are that are run from rc. That also gets rid of the ugly path crond used to have in ps(1) outputs. Further I renamed it to cron, as Paul Vixie likes it and is done by NetBSD. NOTE VERY WELL THE FOLLOWING: 1) Systems crontab changed. Every users crontab resides in /var/cron EXCEPT root's. This is a special crontab as it resides in /etc. Further it is the ONLY crontab file in which you specify usernames. See /usr/src/etc/crontab. This is also done by BSDI's BSD/386 as far as I know (they provided the patches for it anyway) 2) So you must delete root's crontab and reinstall the copy in /etc from /usr/src/etc. 'Must' is to much: the old installed crontab will work but cron will also try to 'run' /etc/crontab. 3) Last but not least: cron's logging is now done via syslog. Note that logging by cron is done lowercase when it logs about itsself and uppercase when it logs user events, like installing a new crontab. The default logfile file is the same as before: syslog.conf:cron.* /var/cron/log -Guido 1994-01-22 20:44:14 +00:00			`#minute hour mday month wday who command`

Add a system to save entropy from /dev/random periodically so that it can be used to reseed at boot time. This will greatly increase the chances that there will be sufficient entropy available at boot time to prevent long delays. For /etc/rc, remove the vmstat and iostat runs from the attempt to provide some cheesy randomness if the files fail, since those programs are dynamically linked, and ldd seems to want some randomness to do its magic. Guidance and parameters for this project were provided by Mark Murray, based on the requirements of the Yarrow algorithm. Some helpful suggestions for implementation (including the tip about iostat and vmstat) were provided by Sheldon Hearn. All blame for problems or mistakes is mine of course. 2001-01-11 13:01:20 +00:00			`# save some entropy so that /dev/random can reseed on boot`

Revert back to rev 1.24 as we have not come to a consensus if is is OK for a hung `daily' run to keep a `weekly' run from happening. Same for `monthly'. We have always run `weekly' and `monthly' reguardless of the execution status of `daily'. Until there is some consensus we should not change the behavior. 2000-12-11 18:38:49 +00:00			`# do daily/weekly/monthly maintenance`
