There are special cases for system entries where these can go in files 
with one or more entries under /etc/cron.d, or cron.daily (etc). 
However, these won't ever show up in anyone's 'cron -l' or 'cron -e' 
commands and thus aren't suitable for things that users will manage 
themselves after the install.
