 > >Description:
 > 
 > 	/usr/sbin/periodic writes it's temporary output files to
 > 	/var/run. Not only does this not match the usage of /var/run
 > 	in hier(9), it means that the periodic program can't be used
 > 	by non-root users!
 > 
 > 	Further, the default output is to send email to root. This
 > 	makes it nearly useless for non-root users.
 > 
 > >How-To-Repeat:
 > 
 > 	Create a periodic directory for some non-root user (in my
 > 	case, the postgresql superuser was doing daily db maintenance
 > 	with it). Then, as the appropriate user, invoke the periodic
 > 	program on that directory. Note that you get no output with
 > 	the default output setup.
 > 
 > 	So change the setting of the _output variables to $USER in
 > 	/etc/periodic.conf. Run periodic again. Notice that it now
 > 	complains about not being able to create
 > 	/var/run/periodic.#### for each file in the directory.
 > 
 > >Fix:
 > 
 > 	Change the value of tmp_output in /usr/sbin/periodic from
 > 	/var/run/periodic.$$ to /tmp/periodic.$$
 $TMPDIR/periodic.$$ if $TMPDIR exists and
 /tmp/periodic.$$ as fallback
 
 > 	Change the value of three _output variables in
 > 	/etc/defaults/periodic.conf to $USER. I have not tested this
 > 	in /etc/defaults, but it does work in /etc/periodic.conf.
