Guys,

we usually put custom cron's into individual users' profile via 'crontab -e'

There are also some system crons in /etc/cron.daily etc...

do you guys put it there? I've learnt from a redhat course that its 'best practice' to put in the indivdual profile. One major difference is putting there, I can control the exact time I want to happen, whereas those in /etc/cron.* are fixed to a time specified in /etc/crontab

other than that... just good habits.

Just wondering: If this is true and that many of you are following suit?

Correct. For cronjobs, you should place them in the user's profile.

For system-level cronjobs, I generally use /etc/cron.{hourly,daily,weekly,monthly} etc. Things I want to stagger go in /etc/crontab and user cron jobs in the individual crontabs.

hmm so what defines a 'system level' cronjob?

Well, cronjobs that backup my entire system (or large parts) to a remote server, cronjobs that update the locatedb, a periodic emerge sync (gentoo), and similar tasks.

At least, that's how I see it: if it's not specific to a user, it's a system job.
