Looks as though all the template-end files have gone, perhaps they were surplus to requirements!
you should really create your own file in
/etc/e-smith/templates-custom/etc/crontab/
(create it if it is not there)
and then the
/sbin/e-smith/expand-template /etc/crontab
will merge the standard ones and the "custom" ones, and they will be preserved across re-boots and upgrades.
