Does anyone else out there use fcron with SL?  I have had it working on 
various systems, compiled from source, for a long time, and currently 
fcron 3.0.6 on SL6.7 is fine.  However, on SL7, when fcron 3.0.6 is 
supposed to send a message containing the output from a job it has run, 
it sends the message ok, but the body is always empty.  (There is a more 
recent fcron 3.2.0 and I've tried that too, but the same thing happens.) 
The /var/log/cron log is uninformative, just reporting that the job has 
run and the message has been sent.  On both SL6 and SL7 I'm using exim 
as mta and mailx as mail program.

I don't know where to look.  Since fcron itself and the jobs it launches 
are running as they should, it's probably not the fault of systemd.  I 
have mailed the maintainer of fcron and will report here if he can shed 
any light.
