A mechanism which already exists is to create /etc/periodic.conf within your
jail, disabling the individual scripts you don't want to run. See
/etc/defaults/periodic.conf for the settings available (or
/usr/share/examples/etc/defaults/periodic.conf)

However it might be a good idea for FreeBSD to provide a sample
periodic.conf for use in a jail environment.
