In GhostBSD (MATE), visit the Startup Applications Preferences to modify your system according to your preferences.
In GhostBSD-XFCE, Session and Startup, Application Autostart tab will enable the same startup customization.
This modification may or may not persist across future updates. This modification will also enable forgetting about updating and leave your system in a potentially vulnerable state.
It would be nice to have deferred timing, weekly, monthly, quarterly, etc... please consider adding an enhancement to the project.
