S5R2's "cron" has a log file for "cron"; the stdout and stderr for each
command are sent to a temporary file which is mailed to the user under whose
UID the job was run, if any output is produced.  (Remember, the S5R2 "cron"
has one crontab per user, and that user can change their own crontab.)

Well, the obvious choice would be the user's shell, but this wouldn't work
for accounts like "uucico".
