Service cron is checked by technique common, in system/common/1.0/cron-setup.st
However, it seems the verification is not totally correct - there's been case of users having malfunctoning cron; and the code to check cron is really smelly (we define the service_name, but simply check for "cron" process name)

We should either check the service using the services generic method (so in 4.1 or more), or have more refined checks on process running and service starting

Not setting the target version, as we need to decide where we need to fix this
