On another note, on the same subject (xServes being disontinued), one feature we use heavily on our os-x server is the ability to load / unload periodic jobs with launchd. With it we're able to schedule jobs let's say every 5 minutes, and so on. One could say I could do something like "*/5 * * * * /path to job" in crontab. True, but the big advendage of launchd in that matter, is that it's 5 minutes between jobs. So if the job takes 6 minutes, we will never have 2 time the same job running at the same time. We even have a job that is scheduled to run every 60 seconds, but can take 2 hours to complete. Is there any scheduler under linux that approch this ? Thanks,
