Case Study Files
The i.cron and r.cron scripts described below are executed by superuser. Editing another user's crontab file as superuser may have unpredictable results. If necessary, change the following entry in each script:
crontab $user < /tmp/$$crontab ||
to
su $user -c "crontab /tmp/$$crontab" ||

Note - If editing of a group of files will increase total file size by more than 10K, supply a space file so the pkgadd command can allow for this increase. For more information on the space file, see "Reserving Additional Space on a Target System".
