• Suppose you have to start some exotic server at boot time. Up until now, you logged in after booting the system and started this server manually using a script named deliver_pizza in your home directory. What do you have to do in order to have the service start up automatically in run level 4, which you defined for this purpose only?
4.6.3. Scheduling
• Use sleep to create a reminder that your pasta is ready in ten minutes.
• Create an at job that copies all files in your home directory to /var/tmp within half an hour. You may want to create a sub-directory in /var/tmp.
• Make a cronjob that does this task every Monday to Friday during lunch.
• Check that it works.
• Make a mistake in the crontab entry, like issuing the nonexistent command coppy instead of cp. What happens upon execution of the task?
