 automatically skips files with certain suffixes that are generally associated
 with backup or extra files.  Any file that ends in one of these will be silently
 ignored:  ~ ^ , .bak .new .rpmsave .rpmorig .rpmnew .swp
+
+The execution of files can be allowed or denied by creating file
+.B jobs.allow
+or
+.B jobs.deny
+which work similarly to other allow/deny config files. The file must be
+created in the specified directory.
+
+Randomization of jobs can be configured in the
+.IR /etc/default/run-parts
+file. To enable randomization of jobs, set the RANDOMIZE parameter to 1
+and set the RANDOM parameter to an integer which determines a random
+seed. Additionally, you may configure the RANDOMTIME parameter (again,
+by specifying an integer) to provide an additional level of
+randomization. Jobs are not randomized when the RANDOM and RANDOMTIME
+parameters are set to 0. Values in these two parameters must be set to
+1 or larger to provide a good enough randomization.
+
+Randomization of cron jobs can be useful for shared networks, where
+multiple cron jobs executed at once can cause spikes in traffic,
+especially during daily jobs. With randomized jobs, the workload is
+evenly distributed throughout the day.
