audit - Enable support for Linux audit subsystem using sys-process/audit
debug - Enable debug code and output. Since version 3.0.5 this will no longer force foreground execution, and fcron will be able to run as a service properly.
mta - Enable mta support for sending emails from fcron
pam - Enable PAM support for fcron. This means that fcron will pass through the "fcron" stack before executing the jobs, and fcrontab will use the "fcrontab" stack to authenticate the user before editing its crontab file.
readline - Enable support for libreadline, a GNU line-editing library that almost everyone wants
selinux - !!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur
system-crontab - Set up fcron to respect /etc/crontab and /etc/cron.d. If this flag is disabled, /etc/cron.d and /etc/crontab will be ignored, but /etc/cron.{hourly,daily,weekly,monthly} will still be respected. Also this creates /usr/bin/crontab symlink.
